Love, love, love this product! It cuts through the nastiest, blackest, grittiest messes my husband can grind into his clothes while working on equipment that comes straight off the oilfield into our shop. I just apply it every nasty spot, throw it in the washer, and set my washer on its heavy duty cycle. Everything comes out on the first wash (no second treatment required), and it doesn't smell like a chemical laboratory.
