Duck Aktiv-Gel Marine

Duck, famously known for its unique 'duck-neck' bottle design, is a prominent brand of toilet cleaners. The brand originated in Switzerland in the 1980s under the name WC-Ente (Toilet Duck), created by the company Düring AG. Its innovative angled neck was designed to reach under the rim of the toilet bowl more effectively than traditional bottles.

In the early 1990s, the brand was acquired by S.C. Johnson & Son, a major American multinational consumer chemicals company. Today, S.C. Johnson manages the brand globally, adapting the name to 'Duck' or 'Toilet Duck' in different markets. While manufacturing occurs in multiple countries to serve regional markets, the brand remains a flagship product in S.C. Johnson’s home cleaning portfolio.
