Recovering Moldy Electronics?

cookiej writes "We just completed having our basement gutted and our house decontaminated from mold. The finished basement is gone, my office floor has been removed as well as 24' of drywall around the base of the room. So, we had a full home theater downstairs along with a couple of computers in the electronics closet that were completely immersed (rainwater, not sewage). We moved them to a sheltered area outside and covered them with a plastic tarp. Since the electronics were off when the water hit them, 1) do I have a chance of recovering them? 2) If so, is there a way to clean them with some sort of liquid bath that would not damage the electronics? and 3) I don't want to bring moldy pieces back in the clean house. How could I decontaminate the electronics themselves, pre-bath? Not looking to save the speakers, just the amp, DirecTV box, video switch, etc. Thanks for any help, here, Slashdot." Read on for more details of this reader's plight.
Early last month, we had about 10" of rain in the course of two hours. Many houses in our neighborhood were damaged. We had rainwater coming in our back door and cascading down the basement steps. We have two sump pumps that weren't keeping up (and of course, no battery backup) and as the water rose in the basement, it was getting dangerously close to the breaker panel. So I made the hard decision to shut down the main power and we got the hell out.

The water reached about 6' in the basement before it drained out. Once we got back, we could not move fast enough to get all the debris out before mold set in and boy did it.

Since we are not in a flood plain, our insurance for this is woefully inadequate. While I would love to just go out and buy replacements, there are far more pressing things to re-buy (washer/dryer, furnace, water heater, etc.) and if there is a chance I can salvage some of this it might be a nice change of luck.

      No! Bleach BAD. Bleach will oxidize all the metals, including the ones you thought couldn't rust!

      I have washed boards in the dishwasher before (no soap!) but that was for spilled liquids. With the presence of mold, you have a different problem.

      First, remove any batteries on the board (coin batteries are common,) as they create a sparking hazard. Use pure isopropyl alcohol (not the 66% stuff) which will mix with remaining water and should help you both clean up and kill the mold. I'd start working over an empty pan, and pour alcohol over it as I cleaned it. Brush everything possible with a natural fiber brush (not a plastic bristled brush that may dissolve.) Get under components with a pipe cleaner. And no smoking around the alcohol, of course! When it's done, drain it. If you have access to it, thoroughly blow it dry with dried compressed air (air from an ordinary shop compressor will contain water and/or oil.)

      Once the visible alcohol is gone, you'll still need to dry the board. It will take time, warmth, and air movement. An oven at the "keep warm" setting (no more than 170 degrees) shouldn't damage the plastics, but not while it's still evaporating alcohol fumes. A fan and some incandescent light bulbs (desk lamps up close) would probably do just as good. Warm sunshine is very good, too (and helps kill mold) but the humidity outside is usually pretty variable, so you wouldn't want it to remain outside in the evening to collect dew.

      However, be prepared for disappointment. If there are electrolytic capacitors on your board, there's a good chance they were already destroyed by the water. They are not typically sealed to ward off immersion in liquids.

The coroner's office couldn't give us any advice. When people die, they leave behind a smell pretty quick. For them, they change clothes on the way out of work and don't take them home.

It helped to get rid of some of the smell, but on most of the metals it touched, it corroded them almost immediately. Things like sink fixtures, outlet screws, door knobs. Think, anything metal that may be in an otherwise emptied bathroom (towels, floor mats, and even the shower curtain had already been removed).

I just left it to sit in the sun for the rest of the day and it worked fine after that. The same quality water, and the toilet was probably worse exposure, and just removing power from it saved it.

      Cleaning With Water:
      1. Disassemble all of the components until you have bare PCB's.

      2. Put them in a dish washer, without any soup.

      Cleaning with IPA:
      1. You can optionally clean the PCB with IPA. I would recommend going with industrial grade IPA, SMT grade is over kill, especially for what you are doing.

      2. Fill a small pan with IPA, and put the circuit board into the pan. Move the pan back and forth, creating a wave with the IPA bath, so that it flows over the circuit board.

      3. Once done, empty the IPA in the container, and fill it up with some clean IPA. Than drop the circuit board in and repeat. This will be your rinse step.

      4. To dry simply use a compressed air gun, or let it evaporate. IPA will evaporate faster than water and will leave fewer residues behind. Further clean IPA has a higher resistance rating than water, or MG Chemicals Super Wash Cat#406B-425G and is tons cheaper.

      *Solvents are commonly used in de-fluxing a PCB after manufacturing. Ionics are your enemy since they can cause corrosion on the leads, and create dendrites which could possibly cause shorts. Therefore sticking to IPA might be easier, unless you have access to DI Water.

      1) While most electronics damage from water is in the form of short circuits destroying components on the boards, it isn't the only form of damage. Being fully submersed for an extended period tends to separate the layers of multi-layered PCBs. It can also cause warping of the boards creating open or intermittent connections. Such damage is often easy to determine visually, but I've seen cases where flexing the board a little or pointing a hairdryer at a particular spot in the board would temporarily alleviate abnormal behavior.

Alcohol with evaporate a room temperature so you won't need much heat. Also, even application of heat is important as heating one part while another is cold can make solder joints pop (So hair driers are out in this case).

      Until 6 months ago, I was managing the production floor at an electronics manufacturing company, so I know a bit about this. (I left for a better job.)
      What to do:
      1. Open the case of the electronic device, and asses the condition of the PCA's. If the traces are corroded, you are probably too late, but you can still give it a whirl.
      2. Use a natural hair scrub brush (Hog hair works really well) and scrub the surface of the board while holding the board under a stream of warm water. Tap water is OK so long as you don't have hard water. If you do, then still use warm water, but finish with distilled water. Unplug any connections, either board to board, or wire to board, and scrub and rinse those as well.
      3. If there is corrosion on the board, scrub it all off, and check the integrity of the circuit traces with a DMM set to ohms or continuity. Repair with appropriatly sized wire. (appx 24 awg for signal, 18 awg for power is a good starting point.)
      4. Use compressed air (make sure it is dessicated, and oil free if it is from a compressor) to blow off as much of the water as you can.
      5. Place the components underneath a heat lamp, or blow the output from a space heater over the device. Let it set for a few hours.
      6. Shake the device out, to make sure all of the water is gone. You should then place a sheet of ESD plastic on top to see if you get any condensation. If you do, keep the heat on. DO NOT LET IT GET ABOVE 150F!!!!! Anything above that is very bad for the solder joints and components.
      7. Put the device back together. Check any moving parts for proper movement (Fans for instance). Replace if bad. Check potentiometers for function: Measure the resistance between the two outer pins. This is the max range of the pot. Now measure from one of the outside pins to the center pin. Turn the knob from one side to the other. At the extreme positions, you will see zero ohms, and the reading you got from measuring the two outside pins. Measure from the center pin to the other outside pin, your results will be exactly opposite if the pot is working properly. Replace with a pot with the same specifications if you don't get the proper results.
      8. Power on the device, and check for functionality. If done properly, and if the electronics weren't wet for too long, then you should have fairly good luck with this. I have cleanded literally tens of thousands of boards this way, and it works perfectly.

      I highly recommend against use of a hair dryer to dry out electronics, and in most cases, anything else, hair excepted. You are very likely to damage the device with concentrated heat.

      The first thing you need to know is the normal level of relative humidity in you area. If it's reasonably low (ie not monsoon season) then all you need is air circulation, not heat.

      I have recovered many water damaged items. A typical example would be full immersion of a digital camera, a rather challenging project due to it's high density, use of cements in lens elements, motor drives, etc.

      Number one, no question whatsoever, is to remove the battery immediately after removal from the wet environment.

      So, as for this particular problem, any device that has a battery and has sat for a day or more after immersion is probably toast and not worth the effort. These days, some rather surprising electronics contain batteries (to retain memory in power outages, for example); open them up and check thoroughly.

      If there is a battery in it, it's probably "done for" right now. Only worth the recovery effort if you need data off the device; it won't live long even if you do get it up and running.

      Corrosion begins the moment you remove an item from the wet environment and place it in an oxygen rich environment, like open air. In fact, broadly speaking, as long as the item is submerged it's fine.

      Nikon, for example, if you call them about a camera that has been submerged accidentally, (besides the advice about batteries above) will recommend any camera that has been immersed remain in water until the moment it's technician examines it ... this means shipping the unit in water if necessary. The service department can then immediately apply the appropriate anti-corrosion solvent before any serious corrosion has a chance to start.

      I normally don't send stuff to Nikon or anyone else for that matter; if you do expect a hefty bill (at least 3 figures, could be more) with no guarantees. Not worth it for most stuff.

      But, I do remove the battery and then set the device in front of a good fan for 3 days or so. If it's raining, leave it there until it's 3 days after the rain stops, or if you live in Seattle and it's winter, at least a very long time.

      For electronics, there are safe cleaning compounds that can be used almost anywhere on the device, and can be used for immersion if necessary. You will need large amounts, and the stuff is not cheap, but depending on your gear may be worthwhile. A quick-and-dirty substitute is automotive Brake Cleaner. These chemicals attack corrosion, displace moisture, and evaporate leaving zero residue.

      For cosmetic cleaning, like faceplates, knobs, etc, I use Bon Ami Foaming Cleanser but that product is not available outside Canada. Try a foaming glass cleanser, but be sure it's safe for chrome, aluminum, and painted surfaces before you use your substitute.

Basically filling up the drop floor, 2' under the floor tiles and 2' on top of the tiles, 4' total of mud (silt) and water. All of our servers, except for the battery units, were not wet, but we had about 2 desktop units fully submersed and 4 submersed to the 2' level. All but 2 of the larger units were plugged in and ON.

      This happened on a Friday morning. They sat over the weekend and on Monday we started the recovery process.

      One by one we pulled the machines completely apart, I mean EVERYTHING that could be removed was removed. Then each part was individually cleaned. First spraying them off with distilled water then by spraying them with an ELECTRONICS cleaner similar to 98% alcohol (you can get the alcohol from WalMart) then they were rinsed again with the distilled water and dried with CANNED / Compressed air. They were then left to dry. We put the units back together a few hours later and fired them right up. We only lost one desktop and that was the last one cleaned. The MOBO battery had corroded in it's slot and ruined the board. Considering each unit was purchased for about $6000 each this was a great savings.

      I also had a situation at home where we had what was essentially a flash flood storm and the window in my daughters room was open.

Rainwater is good in that it is pure. The fact that it contained minerals washed out of the soil is not so good.

Ideally use deionised water, but if that's too expensive (keep in mind the cost of the equipment you are saving), use distilled water or water as pure as your budget allows. If you have the budget use pure water for all the washing, though if you need to save money use clean water for washing and once it is clean finish off with an immediate good flush with the purest water you can afford. A burst of ultrasonic cleaning may help but it is not essential and don't go too mad with it in case you cause damage.

    Leave things heated for at least 2-4 hours.

    Now go back over things with 90% + isopropyl alcohol (it might be hard to find - do NOT use the 70% stuff).

    Why this might not work : the "dissolved" materials which have stuck to the PCB and components do not get washed off completely. They are still present and when you hit the power something shorts - bright lights and probably a decent badda-boom.

    The exposure which the electronics have already experienced have more than likely started corroding the potentiometers, i.e. volume, bass, etc.. controls. So even if things power up they may not work correctly.

    Finally, if you can't take things apart and expose the PCBs and a good portion of the components, then your chances of success are very low. However if you can really get at the compenents this method will work.

This removed ANY moisture under the caps of the 2879s (part number 2SC2879). This netted us about 2 to 3 more volts on the collectors. After talking to engineers, we found that even a LITTLE bit of moisture in there, will turn to steam after the devices reach their internal operating temp. Higher voltage on the collector = higher temperatures (more dissipation). Baking them got us 2 to 3 more volts and that equalled a few hundred more watts (for every 50 percent increase in supply voltage, your Pout doubles) (think, 24 to 64 transistors being combined).

    First factor is how much electrolyte content the water had. I.e. Distilled water is a perfect insulator, no electrolytic content also known as chemically inert. Salt water is at the other end of the spectrum. The reason I know this is from years working on Military electronics in the Navy. The first thing that should have happened would be to immerse the items in as clean of water as possible. This would have reduced the electrolytic properties of the contaminated water by distilling it with the fresh water in a container. Not having that available, then the next step would have been to attempt to clean with any water displacing compount. I.e. WD 40 would work, however that would still need to be removed before operation. The goal would be to break the galvanic corrosion cycle by reducing the electrolyte that provides the return path from the anode to cathode caused by the dissimilar metals. The electronics could still be salvaged if care is taken to thouroughly clean and then "THOUROUGHLY" dry them. I currently work in an industry where we have to repair electronics that are used in Poultry processing, and the rendering process leaves deposits on the electronics that can destroy them if not tended to in a timely manner. Isopropyl alcohol or denatured alcohol will work in cutting oils or other chemicals on a board, however they can also mar the surface of the PCB coatings and leave it prone to corrosive damage unless re-coated with a suitable humidity barrier. Having stated all that, Soap and water to clean is perfectly acceptable, but thourough rinsing to remove the soap and thourough drying is a must. Good luck in the salvage process.

    Most PCs now have bios batteries. Some are very hard to get to too. (macbook for example, UNDER the logic board) We get people that bring in things like that which got a drink spilled in them and told us they instantly removed the battery. It probably helped, but didn't save it. Water + electricity =. electrolysis, and that's a great way to grow shorts.

    Water can be very hard to get out of modern electronics. Surface mount chip packages can hold water for weeks or months underneath them, and the closely spaced pins wick water like you would not believe. If you place a drop of water on the edge of a surface chip like that, the drop will just shrink and disappear, as it's sucked down under the chip. Getting that back out is just as hard as you can imagine.

    You can try to bake the electronics, but you really have to watch the temperature. Lots of plastics in there. I've tossed around ideas like taking a big can of desiccant (like in the "do not eat" packets) and an airtight bag and let it sit that way under a sun lamp for a few days. The idea is the heat doesn't actually remove the water, it just helps keep the humidity mobile. The desiccant WILL pull the humidity out of the air which the warmth has helped free up, and lock it away. Moving air inside the bag would probably speed the process. Remember, more heat isn't necessarily better. Dryer IS pretty much always better. (hope your caps are sealed well...) It's not the heat that dries it out, it's the difference in humidity. (a process accelerated by heat and movement of air)

    Certain things just plain can't be saved. LCD panels wick water into the panel, and there's no easy getting that out without actually disassembling the panel (LCD / polarizers / light spreader / etc) But that's more of a cosmetic thing than functional, so if you don't mind the weird effect it has on the panel, ok for you.

    Home electronics don't often have a bios battery, but many have "supercaps" - high farad count capacitors that keep your settings alive for a few days if power is removed. Those work just like batteries, creating electrolysis in the presence of water. They're soldered down and usually tucked away, so not easy to unplug either.

    Anything with a motor in it is going to be trouble to get water out of. Copper windings can trap water for a very long time. Wire wound and thin film pots can be greatly affected by corrosion and are usually sealed just well enough to hold in water but discourage drying out.

    Even water that appears to be clean can bring in other problems. Grit and light film can form in places it does not belong, interfering with optical gates, clouding lenses in your optical disk players, etc. Optical pots can get their optics clouded or blocked.

    Good luck. I doubt much you do will make a difference at this point - most of your gear was doomed from day 1. Most of what you manage to save probably didn't need your help to survive. (you didn't make a difference) But you can try - just don't blow too much time or expense in vain.

But the electrolytic capacitors are probably in very bad shape. If the electronics have mold on them that means the water wasn't as clean as you might have thought and organic matter got caught up in there. The electrolytics might be unrecoverable meaning the board would be unrecoverable or only work for a short period of time. Similar HDs might work for a short while but don't count on them staying working.

    You can try washing the circuit boards carefully in fresh water (someone mentioned distilled water but a Brita filter will work just fine, disolved minerals don't really hurt anything), but then you have to dry it completely and the only way to do that is in a very low humidity environment... for example, place the board in an oven at its lowest setting (~120 degrees F) for at least four hours. Air conditioning also helps on the humidity front but you also need the heat. e.g. using an oven in an air-conditioned room. You would have to be very careful to protect the board from the oven's heating coils since they tend to turn full on and then full off. And even being careful you might still destroy it.

    If the circuit board is powered on while still wet any metalic surfaces the water touches will corrode over time and destroy the board. The board might work for a short period of time but then it would just die.

Bleach and ozone can kill spores and prevent active spread of the mold, but mycotoxins are nonpolar molecules that tend to dissolve into plastics, making them impossible to decontaminate. The odor may disappear briefly after cleaning, but will return in a few days once the mycotoxins start to diffuse out again. Electronics were the most difficult items to clean, since they are highly porous, filled with plastics, and cannot be subjected to extreme cleaning methods (like boiling in bleach solution, or baking at 400 degrees). If I were you, I would give up. It isn't worth the effort. Despite all our work, we lost everything except smooth metal and glassware.

    Second rule. Take stuff apart. You've got to get that water out and you have got to do it quickly. You aren't going to get water out of the inside of a device quickly through the vent holes or the spaces around the knobs in the chasis. You need to take them apart and expose the boards.

    If the inside is muddy you may consider putting the circuit boards in a dishwasher. I know people whom have done this with computer motherboards and expansion cards. I have not tried it myself though. If you do, skip the soap. You aren't going to eat off the thing anyway, listen to the people whom say chlorine is corrosive. That's what's in dishwasher detergent. Electronics rely on some very narrow copper channels. It doesn't take much to eat through one.

I have used this method to make old items from garage sales or EBay look like new. For this you can use the soap. Again, taking things apart is good. Wherever two parts come together is a crack where water can hide and take a long time to dry. If you do this make sure to remove any wood, paper or cloth parts. You mentioned a home theatre, I imagine there might be grill cloth over speakers. If you had some old style equipment there might be wood trim to remove.

    Make sure everything is completely dry before putting it back together. And of course, remember how it goes together when you take it apart! If it looks real difficult, do it in front of a video camera. Or, stop and take pictures at different steps of disassembly. If there are many different size/type of screw to keep track of, empty egg cartons can be good for that.

    Electronics are pretty hardy and sturdy, helped by the fact that most boards nowadays are covered with a skin that protects from a great many contaminants. When I worked repairing electronics, we used a simple procedure:

    1) Replace all electrolytic capacitors which were older than 7 years or had been exposed to continue high heat. In your case it was submerged, so it's likely that water got inside of them (they're vented) and they should be replaced regardless.
    2) Remove any old style power transformers before cleaning. Modern switching power supplies are ok, much more sturdy.
    3) We scrubbed boards with a toothbrush or small paintbrush using a mixture of water and simple green, though orange based cleaners work well too. We used about a 3:1 (water:cleaner) ratio. Then rinse with water and let air dry. The worst caveat is buttons or other things with tiny space which can hold water. We typically unsoldered those before we cleaned the boards, but if that's not your strong point, just make sure to dry everything before applying power again. A hairdryer and a few days of airdrying works really well in this capacity. Plus it also gives you time to see if mold returns, indicating a spot you should focus on. (I also never came across anything that the cleaner actually damaged, but be watchful for foam or other potentially dissolvable items. We were working on industrial electronics, so the manufacturing process may be a little different.)

If the components are relatively new, and you purchased them from a large retail chain, you may be able to exchange them there. Same goes for DirecTV and the DTV box. Don't forget to check your credit card buyer protection programs as well. Alternatively, you can disassemble your electronics as best you can, and use a high capacity air compressor to blow off all the dust, etc. from the parts. Remember of course to wear a suitable protective mask and face shield while doing this. The internally generated heat from use of the components will probably kill off any remaining mold spores. Check them again in a month and three months, and again a few weeks after your next big rain. The life expectancy of your components will in all likelihood be shortened, but electronics typically work or don't work. When they don't work, you upgrade.

  190. bleach and mold - a summary of suggestions by arete · · Score: 4, Informative

    I've done this too, but not as much as the parent, I'm sure!

    I personally think mold is insidious and terrible, so I'd prioritize getting rid of mold over saving the electronics - but that doesn't mean I wouldn't try. (I rather imagine that most of the boater's stuff has to ALREADY be mold resistant, which does help stop the spread of mold.)

    So I definitely recommend the mild bleach solution. This is increasing the death rate of the mold, but at the cost of reducing the life of your electronics. Since these things were submerged in water, ideally I'd recommend submerging them in a mild bleach solution for perhaps 20 min - ideally rotate/shake them a couple times during this bath.

    If something has a ton of mold on it, you may want to actually WASH this - perhaps with mild soap or mild bleach, and scrubbing until there isn't a big pile of mold. Or it might be enough to let it soak longer (but with more corrosion) and shake it more.

    Then to get RID of the bleach, I'd rinse them with two baths. (Because the first bath becomes bleachy just by the presence of the bleachy item you're rinsing.) In each case I'd give it some time to soak (~20 min) but esp in the first rinse, to make sure it gets all the bleach into solution.

    Tap water is probably fine for the first one, but use distilled water for the second. After a couple items you should replace the second bath - and you might as well replace the first-bath with the water you just stopped using for the second bath.

    Then I'd make sure they were quite dry as fast as possible, so any mold spores the bleach missed doesn't regrow on the damp you just created. The easiest way to do this is baking. 120 is pretty safe - most electronics can handle 140+ without a problem... the sensitive interior components get really hot while running, so the ones you're worried about damaging are usually the outside plastics.

    40 min on one side (including getting it up to temp) and 20 min upside down is probably enough to stop further mold growth. I'd give them hours in the oven or days sitting before I turned them on, though.

    Assuming you have a big pile of stuff to do this to, and 3 large buckets, and an oven as big as all 3 buckets combined, I've just described a 5 step assembly line process, where every 20 minutes you can move something ahead one step.

    For smaller items, or ones you're not taking apart, the last bath could be rubbing alcohol, which would make it dry much faster. But in volume it's considerably more expensive; even distilled H20 is only a dollar a gallon.

    You can do all the above things as a wash instead of a bath, IF you can effectively get to all the surfaces...

    Spraying on a nonconductive corrosion resistor (like the above mentioned products seem to be) sounds like it would tend to extend the life of the device; it might also seal in any remaining mold spores, which I'd consider to be a good thing - but I'd still do a bleach-bath first to kill as much as you can.

    It's a lot of work.

That entailed: 1) removing the side panels 2) hosing it down with a soap spray virtually identical to the one used at your local self-serve car wash 3) rinsing with water 4) Placing the device in the drying ovens for about 3 days. I'm not sure the temp, but it was relatively low, like 150 degrees I think. Care was needed to make sure the transformer devices, which were sometimes in cans, were positioned so they would drain, as they otherwise could pool water that wouldn't dry in 3 days.

    We never had a failure due to water issues, and the devices included old vacuum tube gear with paper caps (waxed, so there's no problem), up to the latest integrated circuit equipment. Almost all of the devices had a CRT & associated high voltage supply as well.

    The moral of the story is, water will generally not hurt electronics if they're powered off at the time. Making sure it's really DRY is critical though, as it may take longer than you think, and if you're not using a drying oven even longer. But soap and water is what we used everyday and it always did the trick.

And what I'm reading here and what my experience tells is you've got a 50/50 shot with every component. My wife dropped her cell phone in a pitcher of grape juice, and without pulling out the battery immediately proceeded to soak it in tap water and then just turned it off... The phone functioned for over a year afterwards (then eventually failed in a most-definitely related way). On the other hand, we had PC's accumulate a little dew over night (while powered off and unplugged, in my office with the windows open...) and just refused to boot the next day. I had a customer who came to me with a PC he'd left on his porch for 2+ years (outside in the rainy northwest) and it worked perfectly.

    The recommendations I've been reading on this post seem to mostly focus on very specific situations. Some people who work with marine electroncis, they may have some really good ideas, but keep in mind the equipment they work with is probably designed to be slightly more water tolerant (not to mention the response/treatment is faster), and the people who work for manufacturers, probably work with specialized hardware (and probably) build to more robust specifications. You have a wide variety of hardware to recover, and you have to treat it as such.

    YMMV, and if I were you, I'd choose the procedures I felt both monetarily and philosophically confident in and spend as little time as is reasonable on each individual component. Dis-assemble everything, clean, do whatever you feel comfortable for drying. I'd invest in some testing hardware power supply testers etc... (may just be me) and systematically eliminate the components that are beyond salvage. EG You don't want to end up frying an entire motherboard/processor/memory because a power supply is dead and beyond rescue. To be safe I might even recommend just biting the bullet and replacing some of the ultra sensitive components... I can't tell you how many MoBo's I've killed in my shop because of a faulty power supply. Even then you will probably find that everything has a dramatically reduced lifespan and I'd start budgeting to replace it. But hopefully you don't have to replace it all at once!
