Highly concentrated, phosphate- and NTA-free, alkaline, high foaming pre-cleaner for car and truck pre-washing. The combination of high-quality complexing agents and special surfactants dissolves even stubborn incrustations such as insects, bird droppings, environmental and rim dirt exceptionally 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 e.g., anodised aluminium. Also eminently suited for copolymer dewaxing. Optimally suited as well for biological service water treatment plants. Quick-separating in accordance with ÖNORM 5106. 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.

Areas of use
Cars, commercial vehicles, construction machines, steel rims and alkali-resistant painted aluminium rims.

Recommendations for use
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 the 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.

Warnings
Do not use it on hot surfaces. Do not let dry. Before using, check suitability and compatibility.
