Best Value

$0.94/oz

A thioglycolate-based gel wheel cleaner that changes color from clear to purple when reacting with iron contamination to indicate optimal rinse timing.

Key Chemistry

pH Level

5.5

Active Mechanism

thioglycolate chelation

Surfactants

2 (anionic, nonionic)

Expert Analysis

Uses monoethanolamine thioglycolate at 7-13% concentration to chelate iron particles while maintaining a mildly acidic pH of 5.5 for effective cleaning without aggressive etching. The gel formulation provides extended dwell time on vertical surfaces, allowing the thioglycolate chemistry to fully react with brake dust and iron deposits before rinsing.

Key Differentiators

  • Visual color-change indicator eliminates guesswork about contact time and reaction completion
  • Gel consistency offers superior surface cling compared to traditional spray iron removers
  • Full ingredient disclosure with 15 components listed for complete transparency

Potential Concerns

  • Contains monoethanolamine thioglycolate which requires proper ventilation due to sulfur-based odor during reaction
  • Not suitable for matte, uncoated, or polished aluminum wheels where chemical etching could cause permanent damage
