Amusingly, my Zyliss kitchen grater's official owner's manual suggests occasionally washing it with gasoline to strip oils and fats. Guess the Swiss have different consumer product safety standards. They didn't even caution to do this outdoors or away from open flame.

I very rarely use gasoline for cleaning -- if I need something that clean, I usually don't want the other contaminants in gasoline, either. Safer to use benzene and give it the respect it deserves.
