About CARPRO Descale

Descale does the one thing a normal shampoo cannot. Over months, minerals from tap water, rain and road spray bond to the surface. The coating still works, but it slows down. Beading gets lazy, gloss goes flat, the paint stops feeling slick. Descale is mildly acidic, so it dissolves that mineral layer and the coating underneath comes straight back.

It is made by CARPRO for their ceramics, including CQUARTZ UK, but it works on any ceramic coating and on uncoated paint too. It will also strip old wax, sealant or spray coating when you want a clean slate before reapplying.

This is not an every wash product. Two or three times a year, or at the start of a detail, is right. Between those, a pH neutral shampoo keeps the car clean without touching the protection.

Why it works

  • Removes what shampoo cannot. Minerals, water spots, hard water film.
  • Restores the coating. Beading and gloss come back without polishing.
  • Strips old protection. Clean slate before a new coating or sealant.
  • Two ways to use it. Foam cannon at 1:10 or bucket at 1:100.

Directions

Bucket wash, 1:100

  1. About 50 mL in 10 L of water.
  2. Wash panel by panel, horizontal surfaces first.
  3. Brief dwell, then rinse thoroughly.

Foam cannon, 1:10

  1. Foam evenly on cool panels.
  2. Maximum dwell without letting it dry.
  3. Rinse, then contact wash if needed.

Light contamination: foam, dwell, rinse, then a normal wash. Heavy: wash directly with Descale, repeat if needed.

Descale or Snow+?

Snow+ is alkaline and handles road film, grime and organic dirt. Descale is acidic and handles minerals and water spots. They do different jobs. A full deep clean uses both, Snow+ first, then Descale, with a rinse between.

Safety
  • Test on an inconspicuous area first.
  • Not in direct sun or on hot panels. Never let it dry on the surface.
  • Gloves and eye protection. Work in a ventilated area.
  • Keep away from children. Store cool and dry.

Reviews Summary
Customers say this car wash effectively revives ceramic coatings and removes stubborn water spots and etching from painted surfaces. Users find it particularly effective for decontamination washes on heavily soiled vehicles, bringing ceramic coatings back to their original beading and sheeting performance after months of use. Many appreciate its ability to strip old wax, sealants, and contaminants while producing good suds with a pleasant smell. The product works well in foam cannons and bucket washes. Some customers note it requires slightly more product than other shampoos but find it cost-effective for its performance.

    Love this product

    After receiving the items and putting it to the test. The quality of the foam comes out just fantastic. After doing deep decon wash the water bedding just comes back like magic

    Cleaned up my coating.

    Hard water had stopped my Carpro coating working well, this works as described. Remove the hard water and got the coating back to its best.
