I was in my garage and spilled gasoline on my slippers and sweat pants. I have washed them twice in the washing machine and they still smell of gasoline.
Any tips on how to get the smell out of the cloths and the washing machine?
If BC's advice doesn't work, I'd put the clothing outside and let it air out. Maybe run the washer thru a few cycles? Vinegar might also work on the washer. Just add some to the wash cycle.
