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 help ensure the test produces consistent, reproducible results.
Testing supports the performance requirements for applicable all-purpose cleaners, sanitary cleaners and hand dishwashing detergents. Our team can discuss the relevant EU Ecolabel protocol for your product.
