W5 Geschirr-Reiniger-Tabs Multi-Active All in 1

W5 is a private label brand primarily associated with Lidl, the German international discount retailer. These dishwasher tablets are a staple of their household cleaning line, designed to provide comprehensive cleaning performance including salt and rinse aid functions. Because Lidl sources its private labels from various chemical manufacturing partners depending on the region and logistics, production typically happens in multiple European countries like Germany, Italy, or Poland.

Originally developed for the German market as an affordable alternative to name-brand detergents, W5 has grown into a globally recognized discount brand within the Lidl ecosystem. The ultimate owner is the Schwarz Group, which is one of the largest retail groups in the world. This ownership structure allows the brand to maintain high quality standards, often winning consumer tests (as indicated by the 'Testsieger' logo on the packaging), while keeping prices low through internal supply chain efficiencies.
