How to Deal with Water and Fog in the Reversing Camera?
3 Answers
First, use a dry cloth to clean the lens surface of the camera, and then use a hair dryer to blow air at the camera for a few minutes. If the water ingress is due to poor sealing of the camera, remove the camera to dry it, and then use sealant for reinforcement. If moisture has penetrated into the components of the camera and the hair dryer doesn't work, it's necessary to go to a repair shop for replacement.
I've driven several cars, and the common issue of fogging or water ingress in the reverse camera is mostly due to aging seals or improper installation. If this happens, first gently wipe the lens with a dry cloth, then park the car outside on a sunny day for a few hours to let the sunlight evaporate the moisture. If that doesn’t work, try removing the camera yourself and use a hairdryer on the cool setting to dry the internal components—be careful not to hold it too close to avoid damaging the parts. Afterward, check the sealing ring; if it’s cracked or hardened, buy a new one at an auto parts store and replace it. Don’t overlook safety—fogging can affect nighttime reversing visibility and increase the risk of collisions. Regular maintenance of the camera is essential, like drying water stains after washing the car to prevent water ingress. The repair cost is low, and doing it yourself is convenient.
I've dealt with foggy cameras several times myself, starting with simple methods. Park and turn off the engine, then gently wipe the lens surface with a soft cloth to avoid scratches, and leave it in a cool, ventilated place for half a day to let the moisture evaporate. If that doesn't work, disassemble the camera cover to absorb the moisture with tissue paper or wrap it in a bag of rice overnight. Then check if the sealing ring is deformed; you can buy a new one online and replace it yourself—it takes time but saves money and is safe. Don't delay if the reversing camera is unclear, as it poses a big risk. For prevention, clean the lens promptly after washing the car and take extra care during the rainy season.
