Clean your fleet of ready-mix trucks quickly and safely with Momar's Bright-Crete Green. It's an acid-alternative, molecular cement dissolver. Safer and better than muriatic acid, phosphoric acid, and hydrofluoric acid. Non-fuming, low odor, non-flammable, and non-corrosive. Safe on glass, paint, diamond plate, aluminum, and chrome. Just apply it in the evening, then rinse it off in the morning. For faster results, use a soft bristle brush 5 minutes after application and then rinse it off.
