Best Value

$0.69/oz

A thioglycolate-based reactive wheel cleaner that uses iron chelation to break down brake dust while indicating contamination levels through color change.

Key Chemistry

pH Level

7.0

Active Mechanism

thioglycolate chelation

Surfactants

1 (nonionic)

Expert Analysis

Uses sodium thioglycolate (5-25%) as the primary iron chelator to dissolve metallic brake dust particles through chemical reaction rather than mechanical action. The neutral pH formulation balances cleaning effectiveness with surface safety, while nonionic surfactants handle organic contaminants like road grime and oils. The color-changing reaction serves as both a visual indicator of contamination levels and confirms active cleaning is occurring.

Key Differentiators

  • High concentration thioglycolate formula (up to 25%) provides stronger iron dissolution than typical reactive cleaners
  • Neutral pH reduces risk of damage to sensitive wheel finishes while maintaining cleaning effectiveness
  • Specifically dissolves the graphite compounds and deposits
  • Has additional additives and cleaners to remove dirt, grime, and tar

Potential Concerns

  • Danger signal word indicates hazardous ingredients requiring careful handling and adequate ventilation
  • Strong sulfur odor typical of thioglycolate-based products may be off-putting to some users
