Yes, I forgot to warn people. The oils in silicone grease
do evaporate slowly over time but there is almost nothing
that will fully remove it. I have had reasonable results
using Brake Clean but you have to be careful
with this also. It dissolves many plastics and most paints.
It is highly toxic and should be used in ventilated
areas only.
 Don't get the grease on anything you don't want it on.
A little of the stuff goes a long way.
