I was given a FW and it had a terrible smell. I changed the felt pad inside that absorbs any oil drips. That helped the machine smell alot. I set the box out in 100 degree sunshine for a few days, but it was still bad. I put some deodorant soap in it recently and sealed it in a big garbage bag, that seams to have worked. I haven't brought it into the house yet, so I'm not sure, it is definately better.
