An anti-scaling agent, also known as descaling agent, anti-limestone, anti-limescale, anti-lime or anti-scale are preparations to prevent the buildup or to remove limescale and fouling. Anti-scaling agent agents usually contain acids such as acetic acid, lactic acid, citric acid, phosphoric acid, hydrochloric acid, sulfamic acid to remove limescale buildup, chelators such as EDTA and phosphonates prevent limescale buildup, and biocides such as sorbic acid to prevent microbial and algal growth.
