Der Waschkönig C.G. Dark & Black liquid detergent

Der Waschkönig C.G. is a brand of laundry detergents and cleaning agents that markets itself as high-quality German-style household chemistry. Although the branding and descriptors are in German (e.g., 'Waschmittel Flüssig'), the brand was developed and is owned by a Polish company targeting the European market, particularly Central and Eastern Europe.

The product range focuses on efficiency and affordable pricing, imitating the aesthetics and perceived quality of traditional German cleaning brands. Most of the manufacturing for this brand takes place in Poland, where the parent company maintains its primary production facilities and distribution center. The brand belongs to the Clovin Group, which has expanded its presence to many international markets.
