Are Keyboards Dishwasher Safe?

i_like_spam writes "Computer keyboards are a breeding ground for bacteria. Studies have shown that keyboards often contain more bacteria than toilet seats. Common cleaning methods, such as pressurized-air canisters and damp rags, help remove some of the dirt, but they also leave behind plenty of grime. National Public Radio describes a recent experiment by a reporter who used a dishwasher to clean her keyboard. Following the advice on Plastic Bugs, she placed her keyboard in the top rack, didn't use the heated dry cycle, and air dried the keyboard for a week afterwards. Her keyboard is now squeaky clean and functions perfectly. Has anyone else tried this or any other alternate keyboards cleaning methods? For those not willing to air dry for a week, dishwasher-safe keyboards are now available. Would you ever do this to your peripheral? "

    Contrary to popular belief, water isn't the real danger to the keyboard here, it's soap. The soap is conductive, and if it isn't fully rinsed, could short out contacts and render the keyboard unusable.

    1. Keyboard you can afford to lose.
    2. No soap
    3. Shake empty of water, then air dry.

      I work in electronics manufacturing.

      Every printed circuit board we make gets washed in a sink with tap water then dried with compressed air. In over 20 years, it's never been a problem.

      It could be more of an issue in places with harder water, but in that case ordinary distilled water would be a poor choice too. You really want deionized water as the ordinary distilled stuff is ridiculously reactive.

      That's because they boards aren't powered when they're washed.

      Keyboards are dishwasher safe in the same way that flash drives or these printed circuit board are dishwasher safe.

      If they can physically survive being immersed in water (I.E. they don't contain stuff that will dissolve) then the water won't destroy them.

      The problem occurs when the keyboard is powered. The water will short every connection in the board and that will cause a very large problem. Someone will probably mention that you could use distilled water to clean it because distilled water won't conduct electricity. However, one website tried running a computer while it was immersed in distilled water. It worked for about 5 minutes and then the water started to dissociate and it shorted the machine out.

      Bottom line, if you want to wash your keyboard then just make sure it's dry before you try to use it.

    About 10 years ago, my friend's mom complained that her computer was acting strangely. It would keep typing the same letters over and over again after a single initial keypress. My dad did some investigation and noticed that this happened on every program, not just the DOS prompt where she noticed it.

    He pressed her on the subject of her keyboard, asking if anyone had spilled anything on it - to which she fervently replied "No". Being the problem solver he is, my dad had brought along his own keyboard to use in testing and lo and behold, everything worked just fine.

    It was about that time (faced with evidence that it was a peripheral problem) that she admitted that there may have been some iced tea spilt on the keyboard a few days prior - but that she didn't think it was any big deal.

    Since my dad had a spare keyboard anyway, he gave it to them in exchange for the tacky one. Once home, he did the very experiment described in the article. He ran the keyboard through the dishwasher (bottom rack) on low heat so as not to melt the keys. Then he propped the keyboard up in front of a floor vent to let the dry, air-conditioned air work on it overnight.

    The next day, he plugged in the keyboard to discover that it was fixed! Back then keyboards had less gadgetry (no numeric side-pad or soft "media" buttons up top), but hey - a win's a win.

    hot water will dissolve the protective layer of grease on the contacts (it's gets runny when hot). You severely degrade your keyboard's life by washing it in a dish washer.

    I've washed keyboards before in the shower by hand (usually in response to spilling beer on them). this is preferable in my opinion. But some keyboard designs do not tolerate washing very well. For example my fairly pricey Sun keyboard was damaged with water because the watered corroded all the contacts (there were wide black streaks, making many of the keys unreliable). it took a good two hours with a pencil eraser to rub the corrosion off the contacts. although the stress or rubbing the corrosion off cracked one of the traces on the very fragile design, forcing me to buy a $15 conductive pen to repair it.

    if you are going to washer it i would also recommend rinsing it with distilled water before letting it dry, a jug of that stuff is like a dollar. and possibly accelerate the drying process with a hair dryer on cold. not hot, unless you want to melt your keys, hair dryers usually get too hot too quickly.

    This is largely true. I'm a retired US Navy Electronic Technician and we used to have a dishwasher in the shop solely for washing electronic circuit boards taken from electronic test equipment. Most equipment is not harmed by exposure to water IF there's no electricity applied. That being said, take care and use common sense, especially if you're dealing with an entire piece of gear and not just a circuit board that's been removed from the equipment. In addition to batteries (and that includes small one's like computer CMOS batteries, which are sometimes soldered to the circuit board), be aware of speakers and other components which can be damaged by water. Some equipment may contain ferrous materials, which will rust or corrode. If you're comfortable with disassembling the equipment, it'll sometimes help both the cleaning and the drying. Even if you don't want to disassemble it completely, it might be advantageous to take the outer casing or shell off the gear after washing to aide in drying. (Be careful not to partially disassemble before washing if there are small or loosely installed parts that can be dislodged by the spraying water.) A heat lamp or bright sunshine will also speed drying, as will a fan. You can even place some boards in an oven at low temperatures. Again, use common sense! A strong heat lamp placed too close to the item or a hot oven can melt or deform some plastics. A couple of hours in the sun doesn't guarantee that all the water is evaporated from all the little nooks and crannies.
