RE: Who has the best homemade cleaning solvent recipe?
Another product recommended to me by someone on this board that I just had a chance to try is Goof Off. I paid $3.75 for a 4.5 oz can at Builders Square. I comes in a metal can and is great for removing plastic sabot crud out of barrels. Just use it outside in the backyard or garage because it's a real stinker.
Like Cayugad's warnings, be careful when using Goog Off near plastic stocks or fiber optics or you'll be eatin' away the good stuff!!
