Frosch WC-Reiniger Zitrone

Frosch is an eco-friendly cleaning brand that was introduced in 1986 by the German company Werner & Mertz GmbH. Based in Mainz, the brand was established as a pioneer in the ecological cleaning market, launching the first phosphate-free household cleaner. The product shown, Frosch WC-Reiniger Zitrone (Lemon Toilet Cleaner), is designed to combat limescale and urine stone using plant-based surfactants and natural citric acid.

The brand is owned and operated by the family-owned Werner & Mertz Group, which is currently led by the fifth generation of the founding family. Manufacturing primarily takes place at the company's main production facilities in Mainz, Germany, and Hallein, Austria. Both sites are recognized for high environmental standards, including EMAS certification. Frosch is well-known for its 'Recyclat Initiative,' ensuring that its packaging is made from 100% recycled plastic, often sourced from domestic recycling systems like the 'Yellow Sack' in Germany.
