Ultimate Iron Remover

Meguiar's Ultimate Iron Remover takes a different approach than their Iron Removing Spray Clay. The pH 4 acidic formula enhances iron reactivity compared to neutral formulas, while the gel consistency (50 cps with xanthan gum) provides dwell time on vertical surfaces. The dual chelator system - thioglycolate for iron plus an aminopolycarboxylic acid (likely EDTA) for broad mineral removal - targets both iron contamination and general fallout. The surfactant system is gentler than Spray Clay, using amphoteric cocamidopropyl betaine instead of anionic sulfates. Benzisothiazolinone preservative is a better choice than the MI/MCI in Spray Clay for users with sensitive skin.

Key Differentiators

• •pH 4 acidic formula - more aggressive than most pH-neutral iron removers
• •Gel formula with xanthan gum for vertical cling
• •Dual chelation system (thioglycolate + aminopolycarboxylic acid)
• •Gentler surfactant system (amphoteric + nonionic)
• •BIT preservative instead of MI/MCI - less sensitizing
• •No eye irritation classification despite acidic pH

Potential Concerns

• ⚠pH 4 conflicts with marketing claim of 'pH balanced formula optimized for paint' - acidic products require more caution on sensitive finishes
• ⚠Strong mercaptan odor noted in SDS - no significant fragrance masking
• ⚠Lower pH may require shorter dwell times to avoid etching on certain surfaces
