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?
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.
