Effective set for quick washing and paint protection

Do you want a clean, shiny car with protection, without spending hours washing or wasting money on expensive cosmetics? This set combines effective pre-wash and protective sealant, which means minimal effort and maximum results!

• Quick and effective washing
• Deep shine without complicated polishing
• Hydrophobic effect for easier maintenance

The set includes:

1️⃣ Koch Chemie Vorreiniger B – for powerful pre-wash

• Effectively removes insects, grease, and road grime
• Alkaline formula (pH 13) for maximum cleaning power
• Phosphate and solvent-free – gentle on surfaces
• Suitable for bodywork, wheels, plastics, and PPF protective films

Vorreiniger B is a powerful cleaner with active foam that dissolves dirt without the need for scrubbing. It effectively tackles insects, road grime, and grease. Thanks to anti-corrosion inhibitors, it is safe even for sensitive surfaces.

Recommended dilution:

• Regular pre-wash: 1:50 (20 ml per liter of water)
• Heavy soiling: 1:30 (33 ml per liter of water)
• Wheel cleaning: 1:10 (100 ml per liter of water)

How to use:

1. Dilute and apply with a foam sprayer or pressure washer.
2. Leave to act for a maximum of 1 minute – must not dry!
3. Rinse thoroughly with water.

2️⃣ Koch Chemie Hydro Foam Sealant – For protection & shine

• Premium sealant with a hydrophobic effect
• Creates an extremely shiny and smooth surface
• Protects against UV radiation, road salt, and dirt
• Reduces dirt adhesion and facilitates subsequent washing
• Suitable for paint, glass, plastics, and convertible roofs

After the pre-wash, Hydro Foam Sealant creates a protective layer that repels water and dirt. The surface becomes extremely smooth, so dirt won't settle as easily.

Recommended dilution:

• Manual application: 1:50 (20 ml per liter of water)
• Pressure washer + foam lance: 1:9 (100 ml per liter of water)

How to use:

1. Dilute and apply evenly to a wet car.
2. Leave to act briefly (must not dry!).
3. Rinse with pressurized water.
4. Dry with a microfiber towel.

Why choose this set?

• Economical – one wash costs only a few crowns
• Fast – washing and protection in one step
• Easy application – no complicated procedures
• Gentle on surfaces – suitable for matte paints and wraps

Result?

Your car will shine, repel water, and washing will be faster than ever before!

What will be needed for application or what to buy for maximum ease of use?

If you don't have a foam lance for your pressure washer, you will need to buy a manual foam sprayer for KCH Vorreiniger B.

We recommend these 2 products:

• iK FOAM PRO 2 Professional Sprayer - Manual Pressure Foamer
• Nuke Guys Super Foamer V2 - Manual Pressure Foamer

For applying KCH Hydro Foam Sealant, a classic sprayer will suffice.

We recommend these products:

• Work Stuff Atomizer - Mixing bottle with sprayer - if a classic is enough
• iK MULTI PRO 2 Professional Sprayer - Manual Pressure Sprayer - if you want convenient application
