An acidic gel wheel cleaner featuring oxalic acid for dissolving brake dust with color-changing visual feedback during the cleaning process. McKee's 37 Foaming Wheel Cleaner Gel has a pH of 2.5, placing it among the most acidic wheel cleaners; lower pH increases dissolving power against mineral deposits but requires more care around delicate finishes. The formulation is also verified biodegradable based on SDS ecological data.

Expert Analysis
The disclosed components include oxalic acid as the primary active ingredient, which chemically dissolves ferrous iron particles in brake dust at a low pH of 2.5. The gel formulation is designed to cling to vertical wheel surfaces for extended contact time, though the complete surfactant system and thickening agents remain undisclosed.
Key Differentiators
- •Thick gel consistency that clings to vertical surfaces and stays where sprayed
- •Color-changing visual indicator that shows active brake dust dissolution
- •Ready-to-use acidic formula requiring no dilution for immediate application
Potential Concerns
- ⚠Strong acidic pH (2.5) requires careful handling and thorough rinsing to prevent potential damage
- ⚠Oxalic acid toxicity necessitates proper ventilation and protective equipment during use
- ⚠Limited ingredient transparency makes it difficult to assess compatibility with sensitive wheel finishes
