I’m going to do some parts for my neighbor (motorcycle hubs and triple trees). I went over to his house, and he’s gotten the parts completely clean of dirt/oil/etc. Beautiful work he did there! However, he’s spent a lot of time masking, and is using bare hands. This, I know, will leave body oil all over the parts. Is there a way to clean this off without ruining his masking job? Can I squirt down with Simple Green, hose off, blow off, and heat in the oven without re-masking everything?
