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?
Alcohol is a fantastic solvent for some things, but it’s a really bad solvent for sugar, which is likely what’s causing stickiness.
70% alcohol will work a bit better than 90 or 99, but only because of the water content. Distilled water will work better though, and is a bit safer than tap water.
The best approach is to strip it down and clean and dry each part. Dumping anything in has a high chance to cause more harm than good.
If it’s a membrane keyboard then there’s a good chance that it’ll die at some point in the future as the (fairly delicate) contacts will be slowly eroded by the liquid.
