I am wondering what is a good product to use to "polish" or brighten up the outside of a black pellet stove. In particular, the cast Harman Accentra. But this could apply to a steel stove as well. I have been using Old English Lemon liquid furniture polish. It seems to work Ok and smells good. I thought the stove polish that Rutland sells in a tube was only for unpainted cast iron? Has a person ever used armorall, WD-40 or turtle wax?
