A thioglycolate-based wheel cleaner featuring 15-40% sodium thioglycolate at pH 5.1 for iron contamination removal. SONAX Wheel Cleaner PLUS features an iron-reactive color-change indicator that turns purple on contact with ferrous brake dust, providing visual confirmation of where contamination is heaviest. The formulation is also verified biodegradable based on SDS ecological data.

Expert Analysis
Uses one of the highest sodium thioglycolate concentrations on the market as the primary active ingredient at 15-40% concentration to chemically break down iron particles through reduction reactions. The mildly acidic pH of 5.1 provides cleaning power while remaining safer than strong acid-based cleaners, with amphoteric surfactants helping to lift loosened contaminants from wheel surfaces.
Key Differentiators
- •High concentration sodium thioglycolate (15-40%) for effective iron dissolution
- •Mildly acidic pH 5.1 balances cleaning power with surface safety
Potential Concerns
- ⚠Warning signal word indicates moderate hazard level requiring proper handling
- ⚠Thioglycolate chemistry may produce sulfur-like odors during use
