Go to an auto parts store and get brake cleaner, Berry mans B-12 carb cleaner, acetone, all work well. Watch it around plastic though. It will melt them in a hurry. I have sprayed with carb cleaner then poured corn starch in there. After it dries I use compressed air to blow in out.


may have to repaet a couple of times but the oil will come out.
