RS — Reactivation Shampoo
Acidic Descaling Wash · Ceramic Coating Reset · pH 3.0 at Dilution
Not your weekly wash. The one you reach for when the coating stops doing its job.
Koch Chemie Reactivation Shampoo RS is an acidic (or descaling) soap designed to help 'reset' the surface performance of a ceramic coating that's lacking. Dissolved solids in water can embed itself into a surface, and that's visible with water spotting as well as the coated surface just not beading up like it used to.
The surface should be pretreated with an alkaline pre-cleaner like Multi Star first (as per Koch Chemie), fully rinsed off, and then be used at a ratio of 50ml for every 10L of water (50ml for around half of a 5 gallon bucket). MEASURE as a pH level of 3.0 is achieved with this dilution ratio.
Reactivation Shampoo RS may also be foamed onto a relatively clean car using an adjusted dilution ratio in the foam cannon to match the bucket ratio (5ml for a 1L bottle). Ensure the vehicle is fully rinsed after washing.
You may use this on any vehicle. The intention is to remove minerals from a ceramic coated or uncoated surface. Reactivation Shampoo can and will remove waxes and sealants. AVOID this drying on a surface, and rinse as necessary to avoid any surface issues.
This is NOT a solution to replace your regular wash shampoo to be used every Saturday — rather, a professional means to solve a problem. If the problem is solved, you revert back to a pH neutral solution to care for the surface until the issue happens again over time.
What it does
Resets ceramic coating performance — acidic chemistry dissolves the mineral deposits and dissolved solids that cause water spotting and kill hydrophobic beading over time.
Removes waxes and sealants — use intentionally. This is a targeted tool, not a maintenance soap. Know what's on the surface before you reach for RS.
Works on coated and uncoated vehicles — ceramic, glass, lacquer, and plastic in the exterior. The descaling chemistry is effective regardless of whether a coating is present.
Strong foaming — works in a wash bucket with a mitt or foamed on via cannon at an adjusted ratio. Foams up nicely on the wash mitt and stays active on panel.
Dilution Guide
Standard
Bucket Wash
50 ml / 10 L
Achieves pH 3.0. ~Half a 5-gal bucket. Measure — don't guess.
Foam Cannon
5 ml / 1 L
Adjusted to match bucket ratio. Pre-clean and rinse the car first.
Real World
3 caps
Into 1.5 gal water. One-bucket wash after foam pre-clean and rinse.
Real World Use: Personally, I just measure out 3 caps of RS, add to 1.5 gal of water, and one-bucket wash the vehicle AFTER it has already been foamed / washed / rinsed. Working 1–2 panels at a time to control time and exposure, I work my way around. This method foams up nicely on the wash mitt/pad, and the measurement feels right on panel. Once completed, the results are there. Obvious. Surprisingly good. Beading is restored, there's a renewed level of gloss and paint clarity — this is a VERY capable solution to address the issue at hand. If you are a professional that deals with maintaining ceramics or an enthusiast with a ceramic that's seen diminished performance, this is such an easy solution. BUY IT.
How to Use
-
1
Pre-treat with alkaline cleaner — foam Multi Star or equivalent onto the vehicle first. Fully rinse off before RS goes on. This removes coarse contamination and sets the surface up correctly.
-
2
Measure your dilution — 50 ml per 10 L of water for bucket wash; 5 ml per 1 L bottle for foam cannon. pH 3.0 is achieved at this ratio. Don't eyeball it.
-
3
Work 1–2 panels at a time — keep the vehicle wet. Wash with a mitt or sponge, managing exposure. Don't let the product dwell beyond what the panel needs.
-
4
Rinse thoroughly — full rinse before any drying. AVOID letting RS dry on a surface. Rinse as necessary to avoid surface issues.
-
5
Return to pH neutral maintenance — once the problem is solved, revert to a pH neutral wash soap for regular Saturday washes until the mineral buildup issue returns.

"It delivered results beyond my expectations leaving an exceptionally clean surface and restoring the coating's hydrophobic properties. As always thank you Scott for solid advice and delivering top tier products."
— Verified BuyerANY TIME YOU ARE WORKING WITH AN ALKALINE OR ACIDIC SOLUTION ON PAINT, you are managing the time of day, exposure to direct sun, NOT working hot panels or other surfaces. Neglecting to use appropriately can cause etching on paint. Work your situation and time of day so you achieve the expected results. This is a product relied on by professionals — anyone can purchase and use it so long as the proper methods are understood first. The ratios mentioned are to keep within VOC compliance standards.
