A ready-to-use thioglycolate wheel cleaner with 10-30% sodium thioglycolate designed for universal compatibility across steel, alloy, painted, chrome, and specialty rim finishes. SONAX Beast Wheel Cleaner 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.
Key Chemistry
pH Level
Active Mechanism
thioglycolate chelation
Surfactants
1 (amphoteric, nonionic)
Expert Analysis
Uses sodium thioglycolate as the primary active ingredient at 10-30% concentration, providing chemical breakdown of brake dust and iron contamination through reduction reactions. The mildly acidic pH of 5-5.3 enhances cleaning effectiveness while remaining gentle enough for sensitive finishes, supported by amphoteric and nonionic surfactants for improved wetting and soil suspension.
Key Differentiators
- •Universal compatibility across all rim types including matte and polished finishes
- •High thioglycolate concentration (10-30%) for enhanced iron removal without aggressive pH levels
Potential Concerns
- ⚠Warning label indicates potential skin/eye irritation from thioglycolate content
- ⚠May require longer contact time compared to more aggressive alkaline formulations
