thioglycolate-basediron-reactivecolor-changingpH-neutralready-to-usewarning-label

A thioglycolate-based iron-reactive wheel and paintwork cleaner that uses color-changing technology to visually indicate iron contamination removal.

Key Chemistry

pH Level

6.4

Active Mechanism

thioglycolate chelation

Surfactants

2 (anionic)

Expert Analysis

Uses sodium mercaptoacetate as the primary iron chelator at 15-30% concentration, creating visible red reactions when contacting iron particles. The pH-neutral formulation (6.4) with anionic surfactants allows safe use across all exterior surfaces while maintaining effectiveness against brake dust and airborne iron contamination.

Key Differentiators

  • High concentration sodium mercaptoacetate (15-30%) for strong iron chelation performance
  • Full ingredient disclosure with excellent transparency rating
  • True pH-neutral formulation that won't strip existing protection layers

Potential Concerns

  • Thioglycolate chemistry produces strong sulfur odors during use
  • Not recommended for vinyl wraps, limiting use on wrapped vehicles
  • Requires pre-washing and may need agitation for optimal results on heavy contamination
