Ajax Bad Spray

Ajax Bad Spray (also known as Ajax Bathroom Spray) is a specialized cleaning product designed for limescale and soap residue removal. The brand, Ajax, was originally introduced by the American multinational Colgate-Palmolive in 1947 as a powdered cleanser. Its famous slogan, "Stronger than dirt!", helped establish it as a household staple across the globe.

While the brand was founded in the United States, its ownership and manufacturing have diversified over the decades. Today, Colgate-Palmolive remains the ultimate owner and manufacturer for the household cleaning line in most international markets, including Europe and Scandinavia. Manufacturing is conducted in various locations globally to serve regional markets; for the European market, products are often produced in countries like Greece, France, or Poland.

In the United States and Canada, the rights to the Ajax laundry detergent line were licensed or sold to third parties (such as Phoenix Brands and later Awesome Products Inc.), but Colgate-Palmolive continues to manage the household cleaners and dishwashing liquids that are most commonly found in retail stores like those in Sweden.
