Koch Chemie RS Reactivation Shampoo — Bring a Coating's Beading Back
When a ceramic coating stops beading like it used to, the coating usually isn't dead — it's buried under hydrophilic film: dust, limescale and mineral salts that water clings to. Reactivation Shampoo is an acidic, strong-foaming wash that dissolves that film and restores the coating's water-repellency and sheeting.
Controlled acidity, used correctly
It's a concentrate at pH 1, but you never use it neat. At the recommended 1:200 dilution it works at around pH 3.0 — acidic enough to descale, mild enough to be coating-safe when used as directed. Wear gloves, and for a heavily soiled car, pre-clean with an alkaline pre-cleaner first so the acid can focus on the mineral deposits.
How to use it
Dilute about 50 ml to 10 L for a hand wash on paint, glass and exterior plastic. Wash, dwell briefly, then rinse thoroughly and dry.

Alkaline lifts organic grime, acid dissolves minerals, neutral foams and washes without stripping your protection. Pick a product for each step from whichever brand you like — the neutral foam is optional.
