I remember the old safety kleen solvent "20years ago" would clean anything and if you had a cut on your hand it would sting like hell! Your hands would turn white cause it would strip the oils. We didn't use no stinking gloves like we do today and we needed them more back then. Heck, I think Italian salad dressing would work better to clean parts than the New "improved safe" diluted mineral spirits you can buy now They are engineering common sense out of society and trying to save us from ourselves sorry rant over
