Fels Napa bar seems to get everything out. It might be difficult to find but it should be in the detergent section. I used it for white baseball pants for many, many years. My DH slipped at the golf course a few days ago (didn't hurt himself) but he was wearing his 100 anniversary Disney golf shirt. The back was mud and grass stained and I didn't think it would ever come clean. He used Zout before I saw it. It hardly touched the stain. I remembered the Fels bar and we used that with some Dawn dishwashing liquid and it came out looking almost like new.
