Baked-on brake dust, flash rust, and tar spots are among the most stubborn contaminants on alloy wheels. Standard car shampoos quickly reach their limits. Professional detailers rely on GBL-based specialized cleaners.
How It Works on Brake Dust and Tar
Brake dust consists of microscopic metallic and organic particles baked deep into the clear coat by extreme heat. GBL rapidly penetrates these baked-on residues, breaking down organic binders without damaging raw aluminum or protective lacquer coatings.
Step-by-Step Application Guide
- Safety Precautions: Wear chemical-resistant gloves and protective eyewear. Work exclusively in well-ventilated outdoor areas.
- Spraying: Spray evenly onto cold, dry wheels. Do not apply on hot rims or under direct sunlight.
- Dwell Time: Allow to act for 1 to 3 minutes as metallic deposits dissolve.
- Rinsing: Rinse thoroughly with a powerful pressure washer.
Conclusion
With proper preparation and a high-purity GBL wheel cleaner, even severely neglected alloy wheels regain a brilliant showroom shine without damaging expensive finishes.
