KOCH-CHEMIE VORREINIGER B
What is so special about the Vorreiniger B?
Koch-Chemie Vorreiniger B (Vb) is a highly concentrated, alkaline, phosphate-free pre-cleaner with an extremely high dirt-dissolving power. This product has been specifically developed for the intensive cleaning of vehicles, motorcycles, and commercial vehicles. Thanks to its powerful formula, it effortlessly removes stubborn dirt such as insect residue, bird droppings, environmental pollution, and grease.
The addition of special corrosion inhibitors ensures high material compatibility with sensitive parts, such as anodized aluminum, provided the correct mixing ratio is used. It is an ideal product for use in both foam lances and manual pressure sprayers for thorough pre-washing.
MANUAL
How do you use the Vorreiniger B?
Depending on the degree of soiling, the product must be applied diluted. For regular pre-washing of the exterior, a mixing ratio of 1:30 to 1:50 is recommended, while for intensive engine cleaning, a stronger mixing ratio of 1:5 to 1:10 can be used. Apply the solution evenly to the dry surface from bottom to top. Allow the product to act for approximately 3 to 5 minutes, but under no circumstances allow it to dry on the paintwork. Then rinse the vehicle thoroughly with a pressure washer.
Tip: Do not use Vorreiniger B in direct sunlight or on hot surfaces. Before use, check the suitability of the material in an inconspicuous area, especially with sensitive metals.
