KnightClean Aquakleen AQ302 is a water-based cleaning solution designed to remove oil, grease, grime, coolant, carbon, dirt, wax, tapping fluid, drawing fluid, and water-based inks. It works using two types of molecules—one that attaches to water-based residues and another that targets oil-based contaminants. With a neutral pH, it is safe for cleaning both ferrous and non-ferrous materials.
