re: Best stain remover for clothes.

Zoat works well for most stuff. For set in stains, saturate the stain with ammonia, squirt it with oxy clean stain remover, let it set for a few hours and wash with warm water. I recently got some 30% ammonia and using the method above cleaned oil stains that had been set in for years in some old blue jeans, shorts and shirts. One shirt was a really nice, expensive dress shirt had a big oil blotch on the front and I didn't have the heart to throw away. Tried all kinds of stuff over the past year that lightened it by about 60% but it was still unwearable. The ammonia + oxyclean spray got it out 100%, you can't even tell it was ever there looking at it up close.
