To properly clean a ceramic coated car, you should use a gentle, pH-neutral car shampoo and a soft wash mitt in a two-bucket method, avoiding automatic car washes with harsh brushes. The coating's semi-permanent SiO2 (silicon dioxide) layer is designed to repel water and contaminants, but abrasive washing techniques can degrade its performance and lifespan. The goal is to maintain the coating's hydrophobic properties without damaging it.
The most critical step is the initial rinse to loosen surface dirt. Use a pressure washer on a wide fan setting or a gentle hose flow to avoid embedding grit into the paint. When washing, a two-bucket method—one for soapy water, one for rinsing your mitt—is non-negotiable to prevent swirl marks. Aggressive circular scrubbing is unnecessary and harmful; let the shampoo lubricate the surface as you glide the mitt in straight lines.
Drying is just as important. Use a clean, soft microfiber drying towel or a leaf blower. Pat or blot the surface dry instead of dragging the towel, which can cause micro-scratches if any dust remains. For maintenance between washes, coating-specific detail sprays can boost the hydrophobic effect. Avoid products containing waxes or sealants, as they can bond to the coating and diminish its self-cleaning ability.
| Recommended Products & Practices | What to Absolutely Avoid |
|---|
| pH-neutral car shampoo (e.g., CarPro Reset, Gyeon Bathe) | Automatic car washes with spinning brushes |
| High-quality microfiber wash mitts and towels | Dish soap or household cleaners |
| Two-bucket method with grit guards | Wiping a dry or dirty surface |
| Coating-safe detail spray for quick detailing | Abrasive clay bars (unless coated-specific) |
| Deionized water for spot-free rinsing | Harsh citrus-based or degreasing shampoos |
Ceramic coatings are incredibly durable but not invincible. Proper cleaning is the single biggest factor in preserving your investment for years.
