Today I was cleaning some lightly rusted rims. I ran out of WD40 and I wasnt finshed cleaning ,so I picked up the closest thing at hand which turned out to be Windex. I sprayed some on the 000 steel wool and got the same results as using WD40 other than my hands smelled better when I finished. It looks like anything works that will lubricate the steel wool. Guess If your a diehard WD40 fan you could always spray some on your hands when your through. :roll: :lol: :lol:
