Muriatic Acid is a strong, corrosive, inorganic acid (HCl), manufactured by absorbing hydrogen chloride in water. It is one of the most corrosive of acids, and is particularly destructive to cellulose, breaking the cellulose chain into even smaller units, resulting ultimately in its complete hydrolysis. It is the same chemical as Hydrochloric Acid.
Uses include cleaning brick, etching concrete, cleaning metal and for swimming pool maintenance. Will attack varnish, fabrics, metals, plastics, most paints and many other materials. Can be diluted with water.
