Active Mechanism
chelation based iron removal
Surfactants
1 (nonionic)
Expert Analysis
Adams uses neutral pH (7-8) with moderate-to-high thioglycolate concentration (5-<10%) for safe but effective iron chelation. The active ingredient (2-hydroxyethyl)ammonium mercaptoacetate is the same as their wheel cleaner but at DOUBLE the concentration for dedicated iron removal. Secondary chelating agent (disodium 4,5-dihydroxybenzene-1,3-disulphonate, aka Tiron) enhances iron chelation. Minimal surfactant system (single nonionic) - relies primarily on chelation chemistry. Grapefruit oil fragrance masks sulfurous odor from thioglycolate.
Key Differentiators
- •pH 7-8 (neutral) - safest for all surfaces
- •Warning signal word - SAFEST iron remover analyzed
- •5-<10% thioglycolate - moderate to high concentration
- •DOUBLE the active concentration vs Adams Wheel Cleaner (1-<5%)
- •100% ingredient transparency - best in class
- •Color changing (orange → purple)
- •Does NOT contain endocrine disruptor
- •Citrus-sulfurous scent (grapefruit oil + thioglycolate)
- •Safe for ceramic coatings and all exterior surfaces
- •Made in USA
- •CRITICAL: Generates toxic hydrogen sulfide gas if mixed with acids
Potential Concerns
- ⚠May cause allergic skin reaction (thioglycolate sensitivity)
- ⚠Causes serious eye irritation
- ⚠Contains CA TACs (2-(2-butoxyethoxy)ethanol)
- ⚠CRITICAL SAFETY HAZARD: Mixing with acids generates poisonous hydrogen sulfide gas
- ⚠Do NOT use with acidic wheel cleaners
- ⚠More expensive than competitors per oz
- ⚠Ready-to-use only (no concentrate option for value)
- ⚠Lower active concentration than CG Decon Pro (10-25%)

Safety Profile
MODERATE HAZARD - Warning signal word (lower than Danger). Causes serious eye irritation and may cause allergic skin reaction. SAFEST iron remover analyzed (vs Danger for P&S Iron Buster and CG Decon Pro). Does NOT contain endocrine disruptor. CRITICAL SAFETY WARNING: Do NOT mix with acidic wheel cleaners - will generate poisonous hydrogen sulfide gas.
