Duck Aktiv-Gel toilet cleaner

Duck, also known as Toilet Duck in many markets, is a well-known brand of toilet cleaner easily recognized by its unique 'swan-neck' bottle design. This specific shape was engineered to allow the user to easily apply cleaning fluid under the rim of the toilet bowl.

The brand was originally invented in Switzerland by Walter Düring in 1980. Its innovative packaging and effective formula led to rapid international success. The brand was eventually acquired by S. C. Johnson & Son, a major American multinational company known for household cleaning supplies.

Today, Duck products are manufactured in multiple locations worldwide to serve regional markets. As a flagship brand under the S. C. Johnson portfolio, it remains a leader in the global sanitary cleaning category, focusing on convenience and hygiene through its gel-based formulas.
