My daughters each worked at a movie theater for a while and their uniforms would always have popcorn oil stains.
NOTHING took it out like Dawn. And I tried everything, ammonia, Fes Naphtha, laundry detergents, you name it. And I soaked them well, too.
However using concentrated Dawn and letting it sit overnight worked EVERY. SINGLE. TIME.
Dawn is also fantastic for removing pasta sauce stains out of clothes. Nothing else gets the tomato stains out like it.
Do I need to buy a special kind of dawn, one of the more powerful degreaser versions?
