How it works
- Chelates minerals — Binds metal ions in water to reduce spotting and loss of cleaning power.
- Cleaning surfactant — Lifts soil off the surface and disperses it in water.
- Alkaline cleaning — Alkaline chemistry that breaks down grease; can stain aluminium and matte finishes.
- anionic surfactants — Ionic types of the surfactants used in this product.

Usage
- Pick a dilution by job: 1:30 to 1:50 for pre-wash, 1:3 to 1:10 for rims, 1:5 to 1:10 for copolymer dewaxing, 1:300 for self-service high-pressure use.
- Apply across the entire surface and let the foam react briefly without drying out.
- Rinse every treated panel thoroughly with a high-pressure cleaner.
- Stay within VDA class A (max 1:300, 5 minutes) or class B (max 1:30, 1 minute) limits, depending on the application.
