Spectrum AR

Spectrum AR is a safe, non-hazardous, low pH salt that acts as a highly efficient acid replacement. It displays the same properties as hydrocholoric acid, phosphoric acid, sulfamic acid, citruc acid, and many other acids and acid blends. Spectrum AR boasts excellent dissolving power over calcium salts, cement residue, and rust stains. It is over 70% as effective as hydrochloric acid with none of the extreme hazards. Spectrum AR is non-corrosive and mild to both skin and steel, making it an effective rust and hard water scale remover for metal surfaces.
