Ultimate Iron Remover

Best Value

$0.54/oz

A consumer-grade thioglycolate iron remover designed to dissolve embedded iron particles and brake dust from paint, glass, and chrome surfaces.

Key Chemistry

pH Level

4.0

Active Mechanism

thioglycolate chelation

Surfactants

1 (amphoteric, nonionic)

Expert Analysis

Uses sodium thioglycolate at 5-10% concentration as the primary chelating agent to dissolve iron contamination through chemical reaction. The mildly acidic pH 4 formulation provides effective iron dissolution while remaining gentle enough for consumer use on painted surfaces. Amphoteric and nonionic surfactants aid in contaminant removal and provide cleaning action.

Key Differentiators

  • Consumer-friendly formulation with moderate thioglycolate concentration for safer handling
  • Multi-surface compatibility for paint, glass, and chrome applications

Potential Concerns

  • Sulfur odor typical of thioglycolate-based iron removers during use
  • Should not be used on bare aluminum or magnesium surfaces without testing
