How to Solve Severe Black Dust on Car Wheels?
3 Answers
When the car is still new, it is necessary to frequently rinse the wheels. First, wet them with clean water, then scrub with a sponge using a cleaning agent, and finally rinse thoroughly with plenty of clean water. If the car has been driven for a while and regular cleaning and maintenance have been neglected, leading to a layer of hard coking on the rims, then a more powerful wheel cleaner should be used.
I've been driving heavy trucks for over 20 years, and wheel hub black dust is a common issue. It's mainly iron powder from brake pad wear mixed with road dust. After every long haul, I first use a high-pressure water gun to clean the wheel hub gaps, then scrub with a stiff brush dipped in soapy water. The key is to dry it thoroughly after washing, otherwise water stains will make dust stick more easily. It's recommended to check brake pad thickness every 5,000 kilometers and replace them promptly if they're too thin. If left uncleaned for long periods, that iron powder can corrode the wheel hub surface, especially for aluminum alloy wheels. After driving on gravel roads in rainy weather, wash promptly to prevent mud from drying on them.
As a car modification enthusiast, I pay special attention to wheel cleaning. The most annoying thing about black dust is that it affects the overall aesthetics. My solution is triple protection: every time I wash the car, I use a dedicated wheel cleaning foam, focusing on scrubbing the back of the spokes where brake dust accumulates; every month, I apply a ceramic coating to the wheels to form a hydrophobic protective film; most importantly, I switch to low-metal formula ceramic brake pads, which reduce dust by 70% compared to ordinary brake pads. By the way, I must remind everyone not to use strong acidic cleaners, as they will corrode the wheel surface. When parking, try to avoid areas with construction dust—these are all lessons from experience.
