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.

    Perfect for Reviving Ceramic Coatings

    I've tried several maintenance shampoos, but Koch Chemie Reactivation Shampoo (RS) really stands out. It does an excellent job removing mineral deposits, water spotting, and contamination that can reduce the performance of ceramic coatings. After washing, my coating's water beading, slickness, and gloss noticeably improved. It foams well, rinses cleanly, and is a great product for restoring that "freshly coated" feeling. Highly recommended for anyone looking to maintain their ceramic-coated vehicle.

    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.
