Soaked overnight with Dawn then 2 wash cycles with added borax just to get the Dawn out but the smell is significantly decreased. It's still there so I'm airing it out. It's only about 60F here so it's not going to dry any time soon. It's an old sweatshirt but I didn't want to toss it. I haven't seen Lestoil in years! I'd completely forgotten about that. Thanks for all the tips! I'm sure others will appreciate it, too.
