This question already has an answer here:
My 1.5 year old son decided to test if my keyboard was compatible with the remains of a can of Red Bull, which obviously wasn't empty enough.
It only affected a few keys, so it was somewhat easy to clean up, using isopropyl alcohol under them, and made sure they were nice and clean.
Now that I've sorted out the sticky keys, I've noticed that they don't behave the same way they used to - There seems to be a lot more friction in them than before, and I'm thinking that I cleaned out some lubricant in the process or that the plastic isn't as smooth as it should be. Either way, I think lubrication should be an easy fix.
Which lubricant should I use on what seems to me as some PVC-like type of plastic? Preferably something dielectric, as I'm likely to use it other places too.
I tried white lithium grease, and while it helped some, it doesn't seem to be fit for the purpose, as it's not viscous enough.
