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
