My parents were both heavy smokers. I washed Mom's fabrics 3 times with oxyclean but couldn't get all the odor out. It was Really bad when I tried to iron some that seemed to smell OK. Old poly lace and cotton/poly blend fabrics were the worst and I had to just toss them finally. Didn't think about vinegar! No amount of sunshine or perfumed detergents helped. Thanks for all the tips- will remember them for next time. Used car shopping today- NO smokey cars for me!
