[R-390] Cleaning sealed pots?

[Larry Saletzki]

Hi all,
I maybe coming into the middle of this thread but I thought I was reading
from the start. The discussion of all the cleaning/lubing agents has been
great. My question is on a sealed pot.  How do you get the stuff in there?
Especially if it is buried in a chassis?
Thanks 73 Larry WA9VRH
