Expert Analysis
303 discloses a simple chelation-based approach with Trisodium NTA (1-10%) and a single nonionic surfactant. The pH of 9.5 is moderately alkaline - enough for cleaning but gentler than products using sodium hydroxide or metasilicate. This aligns with their 'safe for ALL wheels' claim. However, with only 2 hazardous ingredients disclosed, the full formulation strategy is not visible.
