A thioglycolate-based wheel cleaner that uses iron chelation chemistry to dissolve embedded brake dust particles without acids or harsh alkalines.
Key Chemistry
pH Level
6.3
Active Mechanism
thioglycolate chelation
Surfactants
1 (anionic)
Expert Analysis
The product employs sodium mercaptoacetate as its primary active ingredient, which chelates iron particles in brake dust by binding to oxidized metal surfaces and making them water-soluble. This thioglycolate approach operates at a neutral pH (5.5-7.0), allowing effective brake dust removal while remaining safe for wheel coatings and finishes.
Key Differentiators
- •Thioglycolate chemistry provides effective iron removal at neutral pH without the coating damage risks of acid or alkaline formulations
- •Visual reaction indicator changes from clear to deep red as iron particles are chelated and dissolved
Potential Concerns
- ⚠Moderate ingredient transparency with only hazardous components disclosed on SDS
- ⚠Thioglycolate actives may have distinct odor characteristics that some users find objectionable
