My sister brought her FW to me and it stunk! I got a large ziplock and crushed some charcoal briquettes (sp?) into it. Took the case with the machine inside, smushed the opened ziplock into the case and shut the lid as best as I could and let it sit on the patio for 48 hrs. Took care of about 90% of the stink. I think once it's cleaned of the old oil the smell will be gone.
