GLW Series Iron Remover

This product combines moderately high thioglycolate concentration (10-15%) with an alkaline pH (10-12), creating an unusual hybrid approach. Most iron removers use acidic conditions (pH 5-7) to optimize thioglycolate's iron-chelating activity. The alkaline pH here likely comes from sodium hydroxide (confirmed in transport docs but not Section 3). While this reduces iron removal efficiency compared to acidic competitors, it may provide additional cleaning power through alkaline saponification of organic soils. The DANGER classification suggests formulation is at the aggressive end of the safety spectrum.

Key Differentiators

• •ONLY iron remover in database with DANGER signal word
• •ONLY iron remover with H314 Skin Corrosion classification
• •Alkaline pH (10-12) unlike acidic competitors (pH 5-7)
• •No Prop 65 warning (cleaner trace contaminant profile than Turtle Wax)
• •Simple 2-3 ingredient formulation vs complex multi-surfactant systems
• •Low-odor claim (marketing) - may indicate reduced thioglycolate odor masking
• •Made in USA

Potential Concerns

• ⚠DANGER signal word may deter safety-conscious consumers
• ⚠H314 skin corrosion is MORE hazardous than H317 sensitization in competitors
• ⚠Alkaline pH reduces thioglycolate iron removal effectiveness
• ⚠Limited ingredient transparency (trade secret)
• ⚠Transport documentation reveals undisclosed sodium hydroxide
• ⚠Marketing claim of 'safe' conflicts with DANGER classification

MOST HAZARDOUS iron remover in the ChemCX database. H314 Skin Corrosion Category 1C is more severe than H317 Skin Sensitization seen in other thioglycolate products. The combination of H302 (harmful if swallowed) and H314 (severe burns) warrants DANGER signal word. Despite marketing claims of being 'safe,' this requires more careful handling than competing products.
