How to create a self cleaning strong snow foam car pre wash
Koch Chemie Green Star snow foam test with a Lidl Parkside pressure washer and MJJC foam cannon on a dirty Renault Zoe. Is the popular alkaline all-purpose cleaner (APC) any good when used as a snow foam / pre-wash? I tested three dilutions (1 : 20, 1 : 10 and 1 : 5) to find the best foam, dwell time and cleaning power for stubborn dirt, bird droppings and road film.

Why Koch Chemie Green Star (Gs) APC Stands Out
Green Star is a highly concentrated, alkaline-based universal cleaner (pH 12.5) that is free of phosphates and NTA (nitrilotriacetic acid).
- Versatile Dilution Ratios: Because it is an industrial-grade concentrate, you can tailor it to any surface by adjusting the water ratio:
- 1:5 to 1:10 for heavy engine bays, wheel wells, exhaust tips, and grease removal.
- 1:10 to 1:20 for pre-washing filthy lower door panels, bug splatter, and wheel rims.
- 1:20 to 1:120 for interior plastics, textile seats, carpet extraction, and synthetic leather.
- Corrosion & Anodized Trim Safety: Many high-pH alkaline cleaners dull or stain anodized aluminum trim, delicate window surrounds, and plastic seals. Green Star contains specialized corrosion inhibitors that make it significantly safer on delicate trim compared to budget APCs.
- Zero Greasy Residue: It breaks down organic oils, grease, and environmental film effortlessly, rinsing clean with water without leaving a film behind.
