A high-alkaline wheel cleaner utilizing disodium metasilicate for brake dust removal on all wheel types including aluminum.

Key Chemistry

pH Level

11.5

Active Mechanism

surfactant primary with alkaline boost

Surfactants

1 (nonionic)

Expert Analysis

Uses disodium metasilicate as the primary cleaning agent at pH 11.5 to dissolve brake dust and road grime through alkaline cleaning action. The acid-free formulation relies on high pH chemistry combined with nonionic surfactants to break down contaminants without etching sensitive wheel finishes. The streamlined 5-ingredient formula focuses on effective cleaning while maintaining compatibility across wheel materials.

Key Differentiators

  • Disodium metasilicate primary active provides strong degreasing action on brake dust and road grime
  • High pH 11.5 formulation delivers alkaline cleaning power for heavy contamination
  • Surfactant-forward formulation (10-20% ethoxylated alcohols)
  • Lower metasilicate concentration (0.6-1.8%) than competitors

Potential Concerns

  • High alkaline pH (11.5) requires careful handling and thorough rinsing
  • Danger signal word indicates hazardous classification requiring safety precautions

Safety Profile

Signal Word
Danger
Eye Hazard
Eye Damage Category 1 - Causes serious eye damage
Skin Hazard
Skin Corrosion Category 1C - Causes severe skin burns (1C is mildest corrosion subcategory: >1hr to ≤4hr exposure)
Corrosive to Metals
No
Flammable
No

Skin Corrosion 1C is the mildest corrosion subcategory - less aggressive than Meguiar's products. STOT is single exposure only (Cat 3), not repeated exposure like Meguiar's (Cat 1). Overall a more moderate safety profile despite DANGER signal word.
