Duck Aktiv-Gel Fresh

Duck, known as Toilet Duck in some regions, is a well-established brand of toilet cleaners famous for its unique 'duck-neck' bottle design. Invented in the late 1970s by Walter Düring in Switzerland, the curved neck was a revolutionary functional upgrade that allowed users to reach and apply detergent under the toilet rim more effectively.

The brand was later acquired by S. C. Johnson & Son, a global American manufacturer of household cleaning supplies and consumer chemicals. Today, Duck products are produced in various facilities worldwide to serve international markets. The ultimate ownership remains with S. C. Johnson, a family-owned company based in Racine, Wisconsin, USA. The brand continues to lead the category through its iconic mascot and innovations in fragrance and effective limescale removal.
