Breech Plug

buckhunter, I would try less dangerous methods first. (Dangerous if I had to tell my wife what I ran through the dishwasher). Try a good penetrating oil and it will really loosen all of the crud. Acetone won't do any good because it evaporates too fast. After a penetrating oil gets the crud loosened up the acetone will take it right off.
