I recently bought several pairs of Dickies relaxed fit denim painters pants. I guess you could call them stone washed. They had a funny smell thats a cross between a petroleum and Lestoil smell. Prob the chemical used to distress them. They're nice and comfortable but the problem is I've washed them 4 times already and the smell wont come out. I had this same trouble with some Carharrts several years ago. Any suggestions?
