I recently noticed how dirty one of our computer keyboards had become. I tried a baby wipe and it didn't work. I wasn't sure how to clean the keys until my mom suggested trying a damp microfiber. It worked like magic and it was quick too!
Unplug the keyboard. Then slightly dampen a microfiber cloth and gently rub each key until it is clean. Make sure the keyboard is completely dry before you plug it back in and use it.
Microfiber is definitely good for cleaning. I use isopropyl alcohol instead of water for any electronics because it will evaporate entirely. It is also a great glass cleaner.
MF cloth is OK for the top surface, but proper cleaning takes a totally different approach. There are different methods for laptops and regular keyboards.
Laptops: Turn the laptop off. Turn it upside down and rub your flat hand over all the keys to see if any are loose and ready to fall off. If none are loose, vacuum the keyboard thoroughly.
While still upside down, wash it while wearing one of those deep pile fuzzy car washing mitts dipped in warm, soapy dishwater. Use a good dish soap that drips clear on glasses. Let it drip dry while you do the next keyboard.
Finally, vacuum them again and they are clean. If the laptops are in a hospital or sick room environment, do exactly the same, but add a shot of Lysol to the dish water.
Regular Keyboards Slam it upside down onto a sturdy table covered with tarp. No need to be gentle. Today's keyboards are incredibly tough. Slam it again until all the bread crumbs, french fries, onion rings, donut fragments and fossilized jam have been dropped out.
Support the keyboard ends with the keyboard upside down. Shelf brackets are ideal, but anything two hands high will work. Vacuum the upside down keyboard. Get your wet and soapy fuzzy glove, and rub the keyboard.
Again, no need to be gentle! Rub it hard so that the fuzz goes in deep between the keys. Let it drip dry, and vacuum it a bit. Most of today's keyboards are spill proof and a bit of dish soap does not bother them.
For hospital or sick room environments, add a shot of Lysol to the soapy dishwater.
If there were no breadcrumbs, hair, dandruff and dirt involved, you could skip the vacuuming, and just hold the keyboard upside down and rub it with the mitt.
I have cleaned keyboards since the mid-80's and I would highly recommend to vacuum the keyboards as a very important part of the cleaning.
Just wiping the nose with microfiber is not enough.
The best way to clean your laptop or tower keyboard is to turn it over and shake the dust out of it then run the vacuum brush over it. If you have sticky keyboards, you can simply clean them with a damp cloth and small toothbrush.
Unplug and put in dishwasher!
To clean a sticking keyboard, grab a bunch of Q-tips and a bottle of isopropyl alcohol. Gently pop off one sticky key at a time. Clean underneath and press back on.
Even cigarette ashes are bad for the keyboard, also cat hair, dander, and dust. I used to turn the keyboard upside down and gently tap it on the garbage can. A lot of stuff fell out.
I clean my keyboard using the alcohol wipes that are used to clean an area before sticking a needle in you. I have so many of them, the supply company keeps sending me a whole box, and I only use two or three each time I need them.
I use an old blush brush that has been washed and dried to swish away dust and things off my laptop
