Hydrochloric Acid 33%
HYDROCHLORIC ACID - also known as muriatic acid or spirits of salts - is a concentrated, fuming acid suitable for all technical grade applications. It is most commonly used for brick cleaning or concrete etching because of it's ability to dissolve hardened cement quickly without attacking hard stones or brick. HYDROCHLORIC ACID is also used for removing heavy rust and scale from ferrous metals and in many pH adjustment applications such as those required for water treatment and swimming pool maintenance. The concentrated 33.3% w/w Hydrochloric Acid solution is a colourless to yellow fuming liquid which is strongly corrosive and attacks all common metals. The fuming vapours are also corrosive and caution must be taken if using in confined or poorly ventilated areas.
