WC Eend Active Clean Marine Wave

WC Eend, known globally as Toilet Duck or Duck, is a prominent brand of toilet cleaners famous for its unique bottle neck design and its duck mascot. The brand originated in Switzerland in 1980, created by Walter Düring, who designed the 'duck neck' bottle to help the cleaner reach under the toilet rim more effectively.

The brand was acquired by S.C. Johnson & Son, an American multinational privately held manufacturer of household cleaning supplies and other consumer chemicals, in 1991. The product shown in the image is the Dutch market version ('WC Eend'), which highlights the local naming conventions used in Benelux countries.

Manufacturing takes place in multiple locations across Europe and North America to serve global markets. As of 2026, S.C. Johnson remains the ultimate parent company, operating from its headquarters in Racine, Wisconsin. The brand continues to focus on hygiene and ease of use in the household cleaning sector.
