Graham, I don't know if it will work but we use a product called Citrex, a citrus based material, for a lot of different stripping applications. One application is removing dried UR conformal coating from things like spray guns. I recently soaked some fittings that had teflon tape left on them and it disolved the teflon tape. May be worth a shot but I would keep it away from the board material. Ken Bloomquist Sr. Principal Process Engineer PRIMEX Aerospace Company P.O.
