Highly concentrated, phosphate-free, alkaline, high foaming precleaner for car and truck prewashing. The combination of high-quality complexing agents and special surfactants dissolves even stubburn incrustations such as insects, bird droppings, environmental and rim dirt extremely quickly and is therefore ideally suited in particular for heavily frequented carwashes and for non-contact high-pressure washing. Special corrosion inhibitors ensure high material compatibility with regard to sensitive components such as, eg, anodised aluminium. Also suited for copolymer dewaxing. Optimally suited as well for biological service water treatment plants. Quick-separating and tested in accordance with ÖNORM 5106 (test concentration 0.05% mass). VDA conform to class A: reaction time max. 5 min, max. application concentration 1:300. Class B: reaction time max. 1 min, max. application concentration 1:30.
Depending on the dirt accumulation: precleaning: 1:30 to 1:50. Rim cleaning: 1:3 to 1:10. Copolymer dewaxing: 1:5 to 1:10. Self-service high-pressure washing: 1:300. Apply over whole surface, allow to react for a short time and use a high-pressure cleaner to rinse off thoroughly. VDA conform to class A: reaction time max. 5 min, max. application concentration 1:300. Class B: reaction time max. 1 min, max. application concentration 1:30
