I know that sounds like a stupid ass question. I have the Logitech wireless mx keys. I wiped the keyboard down so the surface of the keys aren’t sticky, just hard to press down and some have a spasm.
Since a whole ass thing of coffee did not short it, it gives some credibility that it is water resistant. Can I just dump water on it to help it?
I just rescued a keyboard from a ramen spill over the weekend. There are a few things you can do to make it a bit safer and more reliable than “just dump water on it.”
Power off immediately (incl battery).
Disassemble as much as you’re comfortable – removing the keycaps is a must, opening the case is optional – and use DISTILLED water on any part that may have been coffee’d. Don’t apply pressure or scrub - pour directly onto the components (gravity is your washing pressure) with a tub underneath, then swish the components around in the tub.
Let dry for a day or so, then come back with isopropyl alcohol (at least 95%), cotton swabs, and compressed air. Put your keycaps back in and test each one – any that are still sticky get taken back off, then get a good swab full of alcohol down in the switch or membrane. Use the compressed air to help blow it down in there + assist the drying process.
Let dry for another day or two (until completely dry) before attempting to power back on.
70% isopropyl alcohol is better for cleaning than 95%, water is a key factor in the reaction.
The whole point in using 95% or 99% isopropyl for cleaning electronics is that less water and other potentially conductive impurities get left behind when it dries. Yes 70% is better for general purpose cleaning and it will work on electronics in a pinch but when working with electronics you ideally want the highest concentration isopropyl alcohol that you can get.
I work for a company that manufactures electronics and all of our general product cleaning is done with 99% isopropyl. We will also clean some product with water but that uses highly filtered deionized water and what basically amounts to a fancy dishwasher with a conveyor running through it. That’s also only really done when water soluble fluxes are used, otherwise it’s just the alcohol for cleaning.
