Start with cool paint and clean equipment
Wash in the shade where possible. Follow the instructions for your shampoo, pre-wash and wheel cleaner, and do not let cleaning products dry on the surface.
1. Clean wheels with separate equipment
Use wheel-safe products and dedicated brushes or mitts. Keep abrasive brake dust away from the equipment used on the bodywork.
2. Pre-rinse and pre-wash
Remove loose dirt before contact washing. If using a pressure washer, follow the equipment and film manufacturer’s guidance on pressure and distance, particularly near PPF edges, seals and damaged paint.
3. Let the product work
Use the recommended dilution and dwell time. Rinse thoroughly before it dries. A pre-wash helps loosen contamination but does not remove every particle.
4. Wash gently from the top down
Use clean wash media and a suitable car shampoo. Rinse your mitt frequently or use multiple clean mitts, keeping the dirtiest lower panels until last. Avoid heavy pressure.
5. Rinse and dry carefully
Use clean, soft microfibre towels or a suitable filtered blower. Mineral deposits left as water evaporates can cause spotting.
6. Check the finish
Remove remaining deposits using products compatible with your coating or PPF. Avoid aggressive scrubbing and ask your installer if you are unsure.
Caring for a freshly protected car
Follow the curing and first-wash instructions provided at handover. A ceramic coating makes washing easier, but good technique is still essential.
