00 Null Null Power WC Aktiv Pulver

00 Null Null is a well-established brand in the German-speaking hygiene market, specializing in toilet cleaning solutions. Originally a German heritage brand, it gained fame for its powerful formulas designed to tackle heavy limescale and persistent stains. The product shown, 'Power WC Aktiv Pulver', is a specialized powder that foams upon contact with water to reach difficult areas under the rim.

Today, the brand is owned by S.C. Johnson & Son, a global American manufacturer of household cleaning supplies. While the brand has deep European roots, its production is now distributed across various international facilities within the S.C. Johnson supply chain to serve the DACH region (Germany, Austria, Switzerland). The brand is often marketed under the name 'Duck' or 'Toilet Duck' in other international markets, sharing the same parent company ownership and formulation technology.
