Koch-Chemie (RS) Reactivation Shampoo | Descaling Soap for Ceramic Coatings

Koch Chemie Reactivation Shampoo (RS) is a strong-foaming acidic shampoo designed to deep clean and reactivate ceramic coating performance. It removes hydrophilic contamination such as dust, limescale and salts that can reduce water beading and the easy-clean effect of ceramic-coated surfaces.

Features & Benefits

• Acidic shampoo designed for ceramic coating maintenance
• Helps reactivate hydrophobic performance
• Removes mineral contamination, limescale, salts and hydrophilic dirt
• Strong foaming cleaning performance
• Ideal for coated vehicles with reduced water beading
• Restores the easy-clean behaviour of ceramic-sealed surfaces
• Professional maintenance product for ceramic coatings
• Excellent periodic deep-clean shampoo

Koch Chemie Reactivation Shampoo is a specialist maintenance shampoo designed for ceramic-coated vehicles that have started to lose their water-repellent behaviour. In many cases, a ceramic coating has not failed. Instead, its surface has become blocked by mineral deposits, limescale, salts, dust and other hydrophilic contamination.

This contamination can sit on top of the coating and interfere with the easy-clean and hydrophobic effect. Reactivation Shampoo uses an acidic formulation to loosen and remove these deposits, helping restore the dirt and water-repellent properties of the ceramic-sealed surface.

This makes Reactivation Shampoo a key product for coating maintenance, especially in Australian conditions where heat, hard water, rain, road film and environmental fallout can quickly reduce visible water behaviour.

Use it as a periodic deep-clean shampoo rather than a basic weekly wash. For regular gentle washing, use Gentle Snow Foam or AutoShampoo. After deep cleaning, finish with Hydro Foam Sealant to add a fast hydrophobic maintenance layer.

Pro Tip

If a ceramic coating looks flat or no longer beads properly, do not assume the coating has failed. First perform a decontamination wash with Reactivation Shampoo. Removing mineral build-up can often restore the hydrophobic behaviour without needing to recoat the vehicle.

Frequently Asked Questions

What does Reactivation Shampoo do?

It removes mineral and hydrophilic contamination that can block ceramic coating performance and reduce water beading.

Is it for regular weekly washing?

It is best used periodically as a deep-clean maintenance shampoo for coated vehicles.

Can it restore ceramic coating beading?

Yes, if reduced beading is caused by surface contamination rather than coating failure.

Coating Reactivation Wash

1. Wash only on a cool surface and avoid direct sunlight.


2. Pre-rinse the vehicle thoroughly to remove loose dirt.


3. Dilute Reactivation Shampoo according to Koch Chemie guidance.


4. Wash the vehicle from top to bottom using a quality wash mitt.


5. Pay attention to horizontal panels, lower sections and areas where water beading has reduced.


6. Do not allow shampoo residue to dry on the surface.


7. Rinse thoroughly with clean water.


8. Dry with a quality drying towel.

Aftercare Step

1. Once the surface is rinsed and clean, inspect water behaviour.


2. For additional protection, apply Hydro Foam Sealant or another coating-safe topper.
