How to Deal with Foggy Reversing Camera?
3 Answers
To address fogging on a reversing camera: 1. Surface fogging: Simply wipe it clean with a dry, soft cotton cloth, generally avoiding the use of cleaning agents; 2. Internal fogging: Remove the camera and place it in a drier environment, as the moisture usually dissipates over time. The reversing camera, also known as a parking assist system, reverse visual system, or vehicle monitoring system, is widely used in various large, medium, and small vehicles for reversing or driving safety assistance. Even at night, the reversing camera system provides clear visibility through infrared technology, with professional vehicle-mounted probes offering enhanced anti-magnetic, anti-shock, waterproof, and dustproof performance.
Having driven an old car for many years, I often encounter fogging issues with the reverse camera, usually caused by significant temperature differences or poor sealing. I would first find a safe place to park and check if there are water droplets or steam on the camera lens surface. If present, I simply wipe the surface clean with a soft cloth. If the fogging is inside the lens, I would open the trunk to inspect whether the sealing gasket has aged or loosened, as this may allow moisture to seep in. For DIY solutions, you can gently open the lens housing and use a hairdryer on low heat to dry it out, but be careful not to damage the wiring. If the issue occurs frequently, it’s best to visit a professional repair shop to check the sealing or install an anti-fog film—after all, poor visibility while reversing is dangerous and can easily lead to scratches or accidents. Remember to avoid prolonged exposure to direct sunlight when parking and to dry the car thoroughly after washing to prevent some of these issues.
I enjoy fixing these minor issues myself, so don’t panic if your reversing camera fogs up. Try wiping the lens surface with a soft, lint-free cloth to ensure no dirt is blocking it. If the fog is inside, the lens housing seal might be faulty—check if the rubber gasket is damaged. As a temporary fix, you can use household anti-fog spray or dry the interior with a gentle blow. Avoid rough handling, as it could damage the camera. For prevention, park away from humid environments and use a towel to dry the gaps around the trunk after washing the car. If you can’t resolve it, take it to a repair shop—they can quickly diagnose and fix it, spending a little to ensure safety. Don’t delay too long, as poor reversing visibility increases the risk of hitting walls or obstacles.
