Just to add a bit here as I too am a confirmed Easy Off user.
I've found that it works better if the surface you're treating is warm but not hot mind you. I usually do this type of work outdors and being located in the SW means getting parts warm isn't a problem. This is a little OT but Easy Off is the best product I've found for getting oil out of soaked gunstocks. It will even work on the most miserable old military stocks.
