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

Koch Chemie Reactivation Shampoo (RS) is a specialised acidic car wash shampoo that removes limescale, salts, and stubborn grime, restoring gloss and hydrophobic performance to ceramic coatings.

Unlike a standard pH neutral car wash soap, Reactivation Shampoo is built on a foaming acidic formula designed to target the kinds of contamination that normal car shampoos can’t touch. Over time, ceramic coatings lose their slickness and water-beading behaviour due to layers of limescale, mineral deposits, and salt build-up. RS works to break down and remove these contaminants, revitalising the coating underneath.

By stripping away this invisible barrier, the shampoo helps restore a coating’s gloss, clarity, and hydrophobic performance. Water begins to bead and sheet as it should, giving you the strong self-cleaning properties coatings are known for. Regular use also helps coatings last longer, keeping them effective and easier to maintain.

Reactivation Shampoo is versatile in application: use it in a foam cannon for full coverage, or dilute it in a wash bucket for a controlled hand wash. It fits perfectly into a coating maintenance routine, whether you’re an enthusiast looking to keep your car performing at its best or a professional detailer maintaining customer vehicles.




Features:

  • Powerful Acidic Formula: Effectively removes limescale, salts, and other mineral contaminants.
  • Strong Cleaning Performance: Breaks down dirt, grime, and road film with ease.
  • Coating Revitalisation: Restores hydrophobic water-beading and deep gloss to ceramic coatings.
  • Extended Coating Life: Helps coatings last longer by removing harmful build-up.
  • Flexible Application: Can be used in foam cannons or wash buckets.
  • Maintenance Focused: Ideal for coated cars that need periodic descaling and reactivation.

 

Dilution & Directions

    Foam Cannon:

    • Dilute between 1:15–1:30 depending on contamination levels.
    • Apply foam evenly across the vehicle, allow short dwell time, then rinse thoroughly.

    Bucket Wash:

    • Dilute at 1:200 (approx. 50 mL per 20 L wash bucket).
    • Wash panel by panel with a soft mitt, rinsing regularly.
    • Rinse thoroughly and dry with a microfiber towel.

    Notes:

    • Do not allow the product to dry on the surface.
    • Avoid washing in direct sunlight or on hot panels.
    • For heavily soiled vehicles, use a dedicated pre-wash before RS for best results.

      Used Judicially, this Low pH Car Wash Reinvigorates Amazingly Well

      Works best when used once or twice a year after an alkaline (high pH) prewash. Followed by a refresh of a Ceramic Coating Spray Topper.
