WC Duck Toilet Cleaner

WC Duck, known in many regions as Toilet Duck, is a famous brand of toilet cleaner easily identified by its unique swan-neck bottle design. Invented in the late 1970s, the bottle was engineered to help users reach under the rim of the toilet bowl more effectively. The brand became a household name due to its innovative packaging and effective liquid descaling formulas.

While the brand originated in Switzerland under the Düring AG company, it was later acquired by the American multinational SC Johnson. Today, it is marketed globally under various names such as Duck, Canard-WC, and WC Duck. Manufacturing occurs in multiple locations across Europe, North America, and Asia to serve regional markets, maintaining SC Johnson's presence as a leader in the home cleaning category.
