Koch Chemie Vorreiniger B – powerful pre-wash

Vorreiniger B is a powerful cleaner with active foam that dissolves dirt without the need for scrubbing. It tackles insects, road grime and grease, and its corrosion inhibitors make it safe for sensitive surfaces such as wheels, plastics and PPF film.

• Alkaline formula (pH 13) for powerful cleaning.
• Free from phosphates and solvents.
• Suitable for paintwork, wheels, plastics and PPF protective film.

How to use – Vorreiniger B

1. Apply the diluted product using a foam sprayer or pressure washer.
2. Leave to work for no more than 1 minute – do not let it dry.
3. Rinse thoroughly with water.

Koch Chemie Protector Wax – shine and protection

Protector Wax enhances the appearance of your paintwork with a brilliant shine and forms a protective layer for a long-lasting effect. It improves water runoff from the surface, making drying easier and helping prevent water spots, while improving visibility through the windscreen in the rain. It also cares for rubber and plastic parts, as well as convertible roof materials.

How to use – Protector Wax

1. Dilute the product at a ratio of approximately 30 ml per litre of water.
2. Apply the diluted product to the washed, still-wet car using a spray bottle, pressure spray gun or foam injector.
3. Leave it to work briefly (approx. 30 seconds).
4. Rinse the car with a pressure washer or tap water.
5. Wipe off any remaining water with a drying towel.

Useful extras

If you don’t have a foam lance for your pressure washer, a hand foamer will come in handy for applying Vorreiniger B, such as the iK FOAM PRO 2 or Nuke Guys Super Foamer V2. For applying Protector Wax, a standard spray bottle will do, or you can use the more convenient iK MULTI PRO 2.
