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 of phosphates and solvents.
• Suitable for bodywork, wheels, plastics, and PPF protection film.

How to Use – Vorreiniger B

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

Koch Chemie Hydro Foam Sealant S0.03 – Protection and Gloss

After the pre-wash, apply Hydro Foam Sealant to create a protective layer that repels water and dirt. It leaves the surface smooth, making it harder for dirt to stick and speeding up your next wash.

• Creates a high-gloss, smooth finish.
• Protects against UV rays, road salt, and dirt.
• Suitable for paintwork, glass, plastics, and convertible tops.

How to Use – Hydro Foam Sealant

1. Apply the diluted product evenly to the wet car.
2. Leave it to work briefly – do not let it dry.
3. Rinse with pressurized water.
4. Dry with a drying towel.

Useful Extras

If you don't have a foam cannon for your pressure washer, a hand foamer will come in handy for applying Vorreiniger B, such as the iK FOAM PRO 2 or the Nuke Guys Super Foamer V2. A regular spray bottle is all you need to apply Hydro Foam Sealant, though the more convenient iK MULTI PRO 2 is another option.
