About Calgon
Calgon is the UK's leading water softener brand, protecting washing machines from limescale, rust, dirt residue, and odours for over 65 years. The brand name, derived from 'calcium gone', reflects its core purpose since Ralph E. Hall invented the phosphate-based compound in Pittsburgh, Pennsylvania, launching it commercially in 1933 before bringing it to British homes in 1956. Calgon entered the UK as the first dedicated water softener for washing machines, pioneering a product category that has since become essential for households in hard water areas. The brand began its iconic TV advertising in the UK in March 1985, and these memorable campaigns have made Calgon a household name synonymous with washing machine care and protection. Now owned by Reckitt (formerly Reckitt Benckiser) following a complex ownership history through Merck, Beecham Group, and Benckiser, Calgon has evolved into a comprehensive 4in1 range. Modern Calgon products protect washing machines from limescale buildup, rust, dirt residue, and unpleasant odours, boosting machine efficiency and helping appliances live longer. The brand holds a leading position in European water softener sales. UK shoppers can find Calgon tablets, gel, and powder at Tesco, Asda, Sainsburys, Morrisons, Boots, Wilko, and other major retailers.
