Gentle Wheel Cleaner

surfactant-basedgentle-formulawarning-labelwheel-safeready-to-useacid-free

An acid-free alkaline wheel cleaner designed for regular maintenance cleaning by enthusiasts who wash their vehicles weekly or bi-weekly.

Key Chemistry

pH Level

9.0

Active Mechanism

chelation and surfactant cleaning

Surfactants

4 (anionic, nonionic, amphoteric)

Expert Analysis

This water-based surfactant system uses a blend of anionic, nonionic, and amphoteric cleaners to remove brake dust and road grime without harsh acids or iron-reactive components. The disclosed chelating agent (EDTA) helps break down mineral deposits, while the alkaline pH of 9 provides effective cleaning power that remains safe on all wheel finishes.

Key Differentiators

  • True gel viscosity that clings to vertical surfaces for extended dwell time
  • Multi-surfactant system designed specifically for frequent maintenance rather than heavy decontamination

Potential Concerns

  • Low ingredient transparency with only regulated components disclosed on SDS
  • May require more agitation or stronger products for heavily contaminated wheels or infrequent cleaning schedules
