Car-Chem Clean Wheels is an acid-based spray-on wheel cleaner for most alloy, chromium, painted and plastic-trimmed wheels. The acid base gives it strong cleaning power, and Car-Chem says it lifts heavy contamination such as brake dust, grit and grease. Use it neat for heavy soiling or dilute it 3:1 with water for lighter dirt, spray an even coat, agitate with a dedicated wheel brush and rinse thoroughly with a pressure washer. As with any acid-based cleaner, we recommend working on cool wheels, one at a time, wearing gloves and eye protection, and checking polished, anodised or damaged finishes first. Pair it with soft wheel brushes, a separate wheel bucket and a wheel sealant.
