Choosing the right wash products is not about picking the strongest option. It is about using the correct product at the correct stage.

Koch Chemie offers a structured range that covers the full wash process, from pre wash to contact wash and alternative methods. In this guide, we break down each category clearly so you understand where every product fits.

Understanding the Wash Stages

A safe wash process typically follows:

1. Pre wash to remove loose dirt
2. Contact wash using shampoo
3. Optional methods like rinseless washing

Each Koch Chemie product is designed for a specific role within this process. For a deeper breakdown, refer to the Guide to Snow Foams.

These are used before touching the paint to safely remove loose dirt.

How to Choose the Right Combination

• Light dirt → GSF + NanoMagic or MagicShampoo
• Moderate dirt → Active Foam + shampoo
• Heavy dirt → Vorreiniger B (controlled use) + shampoo
• Coating care → GSF + Reactivation Shampoo
• Low water situations → Rapid Rinseless Wash

In practice, most users rotate based on how dirty the vehicle is.

Practical Wash Process

1. Pre rinse
2. Apply suitable pre wash (GSF, AF or VB)
3. Rinse thoroughly
4. Contact wash with shampoo
5. Rinse and dry using a clean microfibre towel

This follows the two bucket method best practice and reduces paint damage over time.

Final Thoughts

Koch Chemie provides a structured system rather than a one product solution.
