Koch Chemie Vorreiniger B (VB)

Best Alkaline Pre-Wash for Bugs and Road Film

1. Does Koch Chemie Vorreiniger B remove wax?

Yes Koch Chemie Vorreiniger B is a highly alkaline cleaner designed to strip stubborn dirt and grease. Because of its high pH level it will degrade or strip clear carnauba waxes and polymer sealants during the cleaning process. This makes it an excellent choice for a decontamination wash but you should avoid it if you want to preserve a delicate wax layer.

2. Can I use Koch Chemie Vorreiniger B for insects?

Koch Chemie Vorreiniger B is exceptionally effective at removing dried insects and bird droppings. The alkaline formula breaks down the acidic compounds in bug splatter and softens the chitin shell so it can be rinsed away without scrubbing. For heavy insect contamination we recommend spraying a stronger dilution directly onto the affected area before foaming.

3. Is Koch Chemie Vorreiniger B safe for ceramic coatings?

You can safely use Koch Chemie Vorreiniger B on fully cured ceramic coatings to unclog them. Over time coatings can get clogged with traffic film that neutral shampoos cannot remove which reduces water beading. A periodic wash with this alkaline cleaner removes that film and restores the hydrophobic properties of your coating without damaging it.

4. How do I dilute Koch Chemie Vorreiniger B?

Diluting Koch Chemie Vorreiniger B depends on whether you are using it as a pump spray or a snow foam. For a pump sprayer use a ratio of 1:30 to 1:50 for general dirt or 1:10 for heavy grime. If you are using it in a foam cannon you typically need a higher concentration to account for the water mix so adjust until you get a stable clinging foam.
