Calgon Power Gel 4in1 water softener

Calgon is a well-known brand of water softener and washing machine cleaner, originally developed in the United States. The brand name is a portmanteau derived from the phrase "calcium gone." While it started in the 1930s, the brand's ownership has evolved through various corporate mergers and acquisitions. In the European market, Calgon is produced and distributed under the Reckitt Benckiser (Reckitt) umbrella.

Today, Calgon is owned by Reckitt, a British multinational consumer goods company headquartered in Slough, England. The manufacturing for the European market, as indicated on the packaging, takes place within the European Union to serve its extensive customer base. Reckitt continues to manage the brand globally, focusing on household cleaning and hygiene solutions, ensuring its position as a market leader in washing machine protection.
