Best Value
$1.25/oz
16oz
A high-pH alkaline wheel cleaner with iron-reactive chelation technology that combines brake dust dissolution with color-changing contamination indication.
Key Chemistry
pH Level
Active Mechanism
alkaline thioglycolate chelation surfactant
Surfactants
5 (anionic, nonionic, cationic)
Expert Analysis
Uses (2-hydroxyethyl)ammonium mercaptoacetate as the primary iron chelator at pH 10.75 to dissolve ferrous brake dust while providing visual confirmation through color change reactions. The alkaline formulation enhances the breakdown of organic brake dust components while the multi-surfactant system (anionic, nonionic, cationic) ensures thorough wetting and soil suspension across different wheel surface types.
Key Differentiators
- •Combines high-alkaline cleaning with iron-reactive chelation in a single formulation
- •Complete ingredient transparency with only 12 components in ready-to-use format
Potential Concerns
- ⚠High pH of 10.75 requires careful application timing and thorough rinsing to prevent surface damage
- ⚠Danger signal word indicates corrosive properties that could affect sensitive wheel finishes or coatings
