Koch Chemie Vorreiniger B

Before you start washing, Vorreiniger B does the heavy lifting. This alkaline pre-cleaner from Koch Chemie dissolves baked-on insects, bird droppings and road grime before you even pick up a wash mitt. The strong-foaming formula penetrates organic dirt and lifts it off the paint, so you need less friction during the actual wash, which lowers the risk of swirl marks. Vorreiniger B is a concentrated product from the professional Koch Chemie range: diluted according to the dosage, 1 liter lasts for dozens of washes, keeping the cost per wash low. Spray it onto a cool, dry or pre-wetted body, let it dwell for 3 to 5 minutes so the foam can do its work, then rinse thoroughly with a pressure washer before moving on to shampoo. Safe on paint, plastic, rubber and glass, and just as useful on trucks and commercial vehicles that face road grime every day.
