Tips for cleaning old grease Hello, I'm in need of some help. I'm trying to clean an old power drill but the grease inside is very old and gritty. I have tired with soap and water to clean it off and using paper towels to clean out as much as I can. However its in little nooks and cranny that I can reach with my brush to clean. I don't have a parts cleaner and break cleaner via the can't seem to blast it off. I'm wondering what works well for soaking the parts in for the grease to loosen it up so I could blast it away with my air compressor. Thanks!
