Karcher KD-460 Super-Strength Aluminum Brightener- 5 GAL

KD-460 is an extra-strength, acid-based, aluminum brightener designed to tackle the toughest cleaning of truck trailers, aluminum wheels and for preparing aluminum for painting. Do NOT use on glass, polished aluminum or anodized aluminum. It uses ammonium bifluoride, not hydrofluoric acid, and is non-fuming, yet effective in removing grease, oils, baked-on carbon and diesel smoke.
