Recently, I have drenched myself a bit with diesel oil, i.e. a sweatshirt and pants. The clothes went straight to a bowl of water and powder, and then went to the washing machine. Today it is dry, but the stains are left, they are greasy and stink with diesel fuel, so water and powder could not dissolve it. Now I'm wondering how to get rid of it, I think to wash it with denatured alcohol, or some solvent, but I'm afraid that it will discolor the fabric. Anyone have a proven way to get rid of these stains?
