The only time I use Citrasolv is when cleaning out a tin with dried paint in it! I spray the inside of the tin and the lid, cap it, shake it, and let it sit for a few days. Then, I open it and wipe the tin can clean with a paper towel. I dispose of the paper towel in a galvanized garbage can. Citrasolv may be made of natural orange oil, but it is considered much more caustic than Gamblin's gamsol.
