Warning... Silicone grease is persistant stuff and one on what ever
it's very hard to remove. So a board that requires soldering need
that done FIRST then wipe the fingers with a thin film. If you get
Silicone grease on something you dont want it on a it takes a lot
of P11 (tetraflurocloroethane) solvent to get it off and trying to
cook it off with the iron will not win due to very high temperature
resistance of the stuff. Stuff like ethanol and Isopropanol (alchohols)
will not touch it. Most quality contact cleaners that have a lubricant
have some silicone in them.
