Premium pH-neutral iron remover with excellent safety profile and transparency

Key Chemistry

pH Level

7.5

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%)

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.
