A thioglycolate-based iron remover designed for removing ferrous contamination from paint and wheels on all vehicle types. McKee's 37 Xtreme Iron Remover has a pH of 5.0, making it one of the more acidic iron removers; this lower pH boosts reactivity against iron particles but requires caution on chrome and bare metal. It ranks #1 for active thioglycolate concentration, normalized across salt forms to the iron-dissolving anion each formula actually delivers. The formulation is also verified biodegradable based on SDS ecological data.

Expert Analysis
The disclosed chemistry centers on sodium mercaptoacetate as the primary iron chelator at a substantial 25-30% concentration, working at a mildly acidic pH of 5 to dissolve iron particles through chemical reaction. The thioglycolate approach provides the characteristic color-changing reaction that signals active iron removal, supported by anionic surfactants for cleaning and surface wetting.
Key Differentiators
- •High concentration sodium mercaptoacetate at 25-30% for aggressive iron removal
- •Formulated at pH 5 for effective iron chelation while remaining acid-free by traditional standards
Potential Concerns
