Pressure Washing a Ceramic-Coated Car
Use pressure washing to remove loose dirt while controlling nozzle choice, distance, direction and vulnerable edges.

Pressure is useful when controlled
A pressure washer can remove loose contamination before contact washing, reducing the amount of grit reaching the wash mitt. It does not automatically remove bonded road film or eliminate the need for a compatible shampoo.
Follow the equipment instructions and the care requirements for the coating and vehicle surfaces. Avoid universal pressure or distance rules that ignore nozzle pattern, flow and substrate condition.
Protect vulnerable areas
Use a suitable fan pattern and keep the stream moving. Pay attention to film edges, damaged paint, seals, sensors and loose trim. Do not aim a concentrated jet into a lifted edge or joint. Inspect the vehicle before washing so existing problems can be addressed.
Check that the coating has reached the permitted washing stage. Fresh applications may need a different response to contamination during curing.
Complete the wash
After the pre-rinse, use gentle contact cleaning where needed, rinse thoroughly and dry the surface. A clean rinse is important around badges and gaps where detergent can remain. If dirt persists, identify it before increasing force. Targeted compatible chemistry may solve a problem that extra pressure would only make riskier for the finish.
