Hohenstein tests hard surface cleaners and hand dishwashing liquids under controlled conditions. Our objective, reproducible results help you evaluate formulas, support product claims and provide performance evidence for applicable eco-label programs.
We evaluate all-purpose cleaners and heavy-duty degreasers using IKW quality assessment recommendations.
We test dish soap using IKW Part A, “Mileage Through Plate Test.” Soiled plates are washed by hand, and we record the number washed before the foam layer collapses.
The method specifies the sponge or brush and detergent doses. Internal controls ensure consistent, reproducible results.
Hohenstein provides performance testing to support EU Ecolabel applications for all-purpose cleaners, sanitary cleaners and hand dishwashing detergents. Discuss your product with our team to identify the relevant test protocol.
