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.

Another warning. Be very careful using chlorinated solvents near
electrolytic caps. One of the labs I used to service did some studies on
why one of their customers was having a high failure rate with the ends
popping. They found the solvent they were using for flux removal was the
cause. It broke down the seal at the vent hole. The caps were never in
direct contact with the solvent - just the vapors were enough.

Interesting. I hadden thought of that as a potential
problem. Most electrolitic caps now days use that
same bubber seal. I would think that petrolium
oils and ozone from chrona disharge would also
degrade them. Surpisingly, silicone grease is often
used to protect rubber. I would guess, one should
put a light coat of the grease on the rubber
parts before using the brake clean ( found another
use ).
