GLW Series Wheel & Tire Cleaner

3D uses a strongly alkaline approach (pH 10-12) for heavy-duty degreasing. The disclosed Tetrasodium EDTA (0.1-1%) provides chelation for brake dust, while the alcohol ethoxylate surfactant (0.1-1%) aids emulsification. However, these concentrations are far too low to achieve the claimed cleaning performance - the bulk of the active chemistry is undisclosed under trade secret protection.

Key Differentiators

• •Strongly alkaline pH (10-12) - more aggressive than 303 (pH 9.5)
• •Uses Tetrasodium EDTA (not IARC carcinogen, unlike 303's Trisodium NTA)
• •Professional brand with gallon sizing
• •Explicit trade secret claim on ingredients
• •Red colored product (visual differentiation)
• •Both skin AND eye irritation hazards

Potential Concerns

• ⚠Very low transparency - only ~2% of formulation disclosed
• ⚠Explicit trade secret withholding statement
• ⚠pH 10-12 is aggressive despite 'all wheel safe' claims
• ⚠Disclosed concentrations cannot explain cleaning performance
• ⚠Both skin and eye irritation (more hazards than 303)
• ⚠No California RTK expanded disclosure
