A thioglycolate-based iron-reactive wheel and paintwork cleaner that uses color-changing technology to visually indicate iron contamination removal. Autoglym Magma ranks #2 strongest among 36 iron removers in ChemCX's analysis, with a formulation optimized for dissolving embedded ferrous contamination. The formulation is also verified biodegradable based on SDS ecological data.

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
