I have found a safe, nontoxic substance for cleaning release agents from resin parts to prepare them for gluing and painting. I soak the parts for 24 hours in Polident denture cleaner. You can buy it at any drugstore, it’s cheap, and it goes a long way. After soaking the parts I rinse them off with a little dish soap and warm water, let them air-dry, and they’re clean as a whistle. Primer and paint adhere well with no fisheyes, and you can pour the cleaner down the drain with no worries.
