Expert Analysis
Uses ammonium mercaptoacetate at 10-20% concentration as the primary iron chelator, converting iron particles through thioglycolate chemistry that produces the characteristic purple color change. The mildly acidic pH of 5 provides effective iron dissolution while remaining gentle enough for regular use on automotive surfaces.
Key Differentiators
- •High concentration ammonium mercaptoacetate (10-20%) for strong iron chelation performance
- •Mildly acidic pH 5 formulation balances effectiveness with surface safety
