I'm interested in the freezer method. I would spray them with Febreze and put them in a zip lock bag for awhile. I used to smoke and didn't realize how bad it smells. Glad I quit almost 2 years ago. I had to wash my entire stash with Oxyclean, detergent, and an enzyme additive. Got rid of the smell but took me about 10 days and I had to iron everything. Electric bill was over $10.00 higher for that month.
