Expert Analysis

Griot's offers two distinct wheel cleaners: the regular Wheel Cleaner (pH 7.5-8.0, surfactant-only, gentlest approach) and this Heavy-Duty version with thioglycolate iron-reactive chemistry. This positions them to serve both the 'gentle maintenance wash' and 'heavy brake dust removal' use cases. The 3-5% thioglycolate concentration is competitive with similar products. Zinc salts for odor masking is a nice formulation detail - thioglycolate has a characteristic sulfur smell that some users find objectionable.

Key Differentiators

  • Iron-reactive color-changing formula
  • Xanthan gum gel for vertical surface cling
  • Zinc salts to mask characteristic thioglycolate sulfur odor
  • pH-neutral approach safe for all wheel finishes
  • 3-5% thioglycolate concentration - mid-range for category
