How should ADAS cameras and sensors be cleaned?
Short answer: Clean camera windows and sensor faces gently with a soft cloth, mild cleaner and water; avoid abrasive pads, high-pressure spray up close and heavy coatings that change how sensors see.
Most ADAS complaints in winter come from dirt, salt film and ice on sensor surfaces. Forward cameras look through the windshield, so a clean inside and outside of the glass in front of the camera matters. Film from interior plastics can build up on the inside of the glass and blur the image.
Radar covers and emblems should be washed with soap and water. Avoid scraping them with ice scrapers or abrasive pads, which can scratch the surface. Ultrasonic parking sensors should be kept free of mud, stickers and heavy wax.
When pressure washing, keep the nozzle at a distance from sensors and seals, because water forced into a sensor or connector can cause faults. If a customer has added window tint strips, film or accessories near the camera or radar, remove them or check whether they interfere, since anything in the sensor's field of view can reduce performance and safety.
