Yeah, been there, done that, got the T-shirt, also got the bill from the psycho ward. Let a good smith do it (if he will). Otherwise, flush, blow dry, and light oil. Polishing the mating surfaces on the sear will help with trigger pull, but wont remove the heavy pull, just makes it smoother so that it feels like it has been lightened. Be careful even when polishing.
No such thing as a stupid question. What is stupid is not asking it.
