From Koch-Chemie's technical data sheet for Vorreiniger B (Vb) (a PDF on this page), in our words: Depending on soiling, dilute 1:30 to 1:50 for precleaning, 1:3 to 1:10 for rims, 1:5 to 1:10 for copolymer dewaxing and 1:300 for self-service high-pressure washing, then cover the whole surface, allow a short reaction time and rinse off thoroughly using a high-pressure cleaner. For VDA conformity, class A limits the reaction time to a maximum of 5 min at a maximum application concentration of 1:300, and class B to a maximum of 1 min at a maximum of 1:30. Check the sheet's warnings before first use, and where this differs from the sheet, follow the sheet.
