There are always some dark “stubborn stains” on the steel rim of car tires, which cannot be washed off by lotion. How to remove them?
The dark black material on the rim is not from the external environment, but from the brake pads.
When the vehicle is braking, the friction between the brake pads and the brake disc will produce some toner, which will fall on the rim, because the rim is also prone to heat when rolling, especially when braking. This heat will cause the toner to coke on the rim, and if not cleaned for a long time, it will form a brown hard substance that is difficult to wash off with water.
When the car is braking, the center of gravity of the vehicle will move forward, and the weight of the front of the car itself will be heavier, which will make the braking burden of the front wheel larger, that is, the carbon left by the front wheel braking. If the powder is more than the rear wheel brake, the front wheel will be darker.
This kind of substance is not impossible to clean. The more common cleaning methods are:
1. Toilet cleaning spirit. I have to say that the cleaning effect is really strong, but after brushing the toilet cleaner, rinse it with clean water in time.
2. Special wheel cleaning agent is used for cleaning, and the effect is very good. You can buy it online or go to a car wash for cleaning.
