vinegar is my magic smell remover. Soak it in it, then hang it out in the sun. I had some towels with a terrible odor from storage and it worked like a charm. Some say lemon juice, but I have had better luck with vinegar. My daughter rented an apartment, where someone had a cat and didn't keep it clean, you know the smell is hard to get rid of. She hates the smell of vinegar, but I talked her into trying it. Sprayed the whole place down, came back later and ohhhhhh so much better. it doesn't stay vinegar smelling, that smell goes away. :-o
