To wash a ceramic coated car, rinse off loose dirt first, wash with clean mitts and a gentle car shampoo, keep wheel tools away from the paint, rinse thoroughly and dry with clean, soft towels. The coating makes the job easier, but your technique still decides whether you add marks.
Always follow the curing and first wash advice from whoever applied your coating, where it differs from the general guide below.
How Bay Does ItBay's Full Detail starts with a snow foam pre-wash and a hand wash, panel by panel. The routine below follows the same idea for washing at home.
What You Need To Wash A Coated Car
- A hose or pressure washer
- A gentle, pH neutral car shampoo
- Two or three clean wash mitts
- Separate brushes and a separate mitt for the wheels
- Two buckets, one for soapy water and one for rinsing the mitt
- Soft, clean microfibre drying towels
Clean tools matter more than fancy kit. A mitt that has been dropped on the driveway should go straight in the laundry, not back on the paint.
Step 1: Pick The Right Time And Place
Wash in the shade, on cool panels, early or late in the day if you can. In a Hawke's Bay summer, paint in full sun heats up fast, and shampoo and water dry on it before you can rinse.
If the car has been sitting in the sun, give it time to cool down first.
Step 2: Clean The Wheels First
Wheels carry brake dust and road grime you do not want on your paint. Use separate brushes and a separate mitt, and rinse them well before you move on.
Step 3: Rinse Or Pre-Wash
Rinse from the top down to knock off as much loose dirt as you can before anything touches the paint. Pay attention to the lower panels, wheel arches and grille.
A foam pre-wash helps soften road film on a dirty car. On a car coming back from a dusty orchard road or a beach car park, this step does most of the heavy lifting.
Step 4: Wash Panel By Panel
Start at the roof and work down, one panel at a time. Use light pressure and straight lines, and rinse the mitt often. Leave the dirtiest lower sections until last, ideally with a separate mitt.
If something will not shift, do not press harder. Come back to it after the wash with the right product.
Step 5: Rinse Thoroughly
Rinse shampoo out of the seams, mirrors and badges. Watch how the water behaves, but do not judge the coating until the car is properly clean.
Step 6: Dry It Properly
Do not let the car air dry in the sun, because droplets can leave mineral spots on top of the coating. Use clean, soft drying towels with light pressure, or blow water out of the gaps.
How Often Should You Wash A Coated Car
Wash it when it is properly dirty rather than on a strict schedule. A daily driver parked outside will need it more often than a garaged weekend car.
Remove bird droppings, bugs and salt spray sooner. Coastal cars around Napier, Ahuriri and Westshore benefit from a rinse after a windy day by the sea.
What To Avoid On A Coated Car
- Automatic brush car washes
- Dishwashing liquid or household detergent
- Dirty or dropped mitts and towels
- Wiping a dusty car dry
- Polishes or cutting compounds used as cleaners
- Unknown waxes or sprays over the coating
- Scrubbing at bird droppings or bugs
Can You Use A Touchless Car Wash
A touchless wash avoids brushes, which is a big improvement. The trade-off is that it often relies on strong chemicals to make up for the lack of contact, and it can leave a film of road grime behind.
As an occasional quick rinse when you are short on time, it is far better than a brush wash. As your only way of washing a coated car, it is not ideal.
What If The Water Beading Gets Weaker
Start with a thorough wash, because road film is the most common reason a coating looks tired. If the beading is still patchy on a clean car, the paint may need a gentle decontamination, so get advice before reaching for a clay bar or polish.
