Toilet Duck

Toilet Duck, commonly known in many markets as Duck, is a famous brand of toilet cleaner easily recognized by its unique duck-neck shaped bottle. This innovative design was originally patented in the 1980s by Walter Düring in Switzerland to allow for easier application of the cleaning fluid under the rim of toilet bowls. The brand's distinctive shape and effective disinfecting formula quickly made it a household name across Europe and eventually globally.

The brand was later acquired by S.C. Johnson & Son, a major American multinational consumer chemicals company. Today, production of Toilet Duck and its various iterations (such as Fresh Discs and liquid cleaners) occurs in multiple countries, including the United Kingdom, Germany, and the United States, to serve regional markets. It remains one of the flagship brands in the S.C. Johnson home cleaning portfolio, maintaining its market position through continuous innovation in toilet hygiene technology.

While the original inventor was Swiss, the brand is now firmly established as an American-owned global property. In different regions, it is marketed simply as 'Duck' or 'Canard-WC,' but it consistently features the iconic mascot and the signature curved bottle design that defines the brand's identity.
