CarLab Sour Power is a highly concentrated acidic shampoo and active foam in a single product. It has been developed for regular and periodic car washing, with a particular focus on vehicles protected with Coating – to remove mineral contamination and restore the hydrophobic properties and gloss of the Coating.

The product can also be used on vehicles without a protective Coating to remove light water spots from paintwork and glass. CarLab Sour Power foams heavily, provides excellent lubrication, and rinses off easily without leaving residue.

Unlike many similar products, CarLab Sour Power contains no hydrophobic additives, making it suitable as a preparation wash prior to the application of a new Coating or Sealant. See more CarLab products for car care in our range.

What is CarLab Sour Power and why choose it?

CarLab Sour Power is a low-pH acidic detergent that effectively dissolves mineral deposits, limescale marks, and light water spots without attacking the paint surface. The acidic formulation is specially adapted for vehicles with Ceramic Coating or other protective Coating, where alkaline shampoos can, over time, degrade the surface's hydrophobic performance.

The product is free from hydrophobic additives, meaning it does not interfere with subsequent treatments using Coating, Sealant, or wax. This makes CarLab Sour Power a reliable choice for detailers and reconditioning workshops that require a neutral, clean result after every wash.

Where is this product suitable?

• Vehicles with Ceramic Coating or other protective Coating
• Vehicles without Coating with light water spots on paintwork or glass
• Professional reconditioning workshops and detailing studios
• Car care businesses with regular vehicle washing schedules
• Detailing enthusiasts carrying out maintenance washing at home

Frequently Asked Questions (FAQ)

Can CarLab Sour Power be used as an active foam pre-wash before applying Coating?

Yes. CarLab Sour Power can be used as an active foam pre-wash prior to the application of a new Coating or Sealant, precisely because the product contains no hydrophobic additives. This means the paint surface is left clean and neutral after rinsing, without interfering with the adhesion of subsequent Coating layers. The dilution ratio for active foam is 1:4 for compressed air foam cannons and 1:40 for manual foam cannons.

What volume and dilution ratios apply to CarLab Sour Power?

CarLab Sour Power is supplied in a 750 ml bottle. As a shampoo, the product is diluted at 40–50 ml per 10 litres of lukewarm water for maintenance washing, and 50–100 ml per 10 litres of water for Coating service. As an active foam, the dilution is 1:4 for compressed air foam cannons and 1:40 for manual foam cannons. The product must always be used diluted and should not be applied to hot surfaces.

What sets CarLab Sour Power apart from other acidic shampoos on the market?

CarLab Sour Power combines the functions of an acidic shampoo and an active foam in a single concentrate, providing flexibility in the workflow. A key characteristic that distinguishes CarLab Sour Power from many similar products is the absence of hydrophobic additives. This makes the product suitable both for regular maintenance washing of Coating-protected vehicles and as a neutral cleaning step prior to a new surface treatment.
