Expert Analysis
Meguiar's Ultimate All Wheel Cleaner uses sodium thioglycolate as its primary active ingredient to break metallic bonds in brake dust and road grime, while maintaining a neutral pH of 7 to protect wheel finishes. The formulation combines this thioglycolate chemistry with nonionic and anionic surfactants to lift loosened contaminants from wheel surfaces. This approach allows the cleaner to tackle embedded brake dust without the acidity that can damage sensitive wheel coatings.
Key Differentiators
- •Neutral pH thioglycolate chemistry offers iron removal without the corrosion risks of acidic alternatives
- •Universal wheel compatibility including delicate finishes that require acid-free formulations
Potential Concerns
- ⚠Thioglycolate compounds have a characteristic sulfur odor that some users find unpleasant
- ⚠May require longer dwell times compared to stronger acidic cleaners for heavy brake dust buildup
