1. Step 1: Before cleaning the wheels, all brake systems must be wrapped in plastic bags to prevent different detergents from contacting the brake systems.

2. Step 2: Clean the wheel hub and tire with WD40 oil stain remover and brush. After the hot summer, because the asphalt on asphalt pavement will volatilize oil vapor under baking, this oil vapor will be adsorbed on the car body after mixing with dust and impurities in the air. If the oil attached to the wheel is not washed off, the wheel hub will become dirtier and dirtier, and the tire surface will soften quickly, so washing off the oil on it is the most basic. WD40 oil stain remover is very suitable for this job. After brushing it all with a brush, just rinse it with clear water.

Step 3: After the tires are naturally air-dried, start to maintain the tires. This time, WD-40 high-efficiency silicone lubricant, which can maintain rubber, is used instead of any tire maintenance agent, because after most tire maintenance agents are stopped, the same problem will occur-tire yellowing. Because these maintenance agents will absorb dirt, dust and iron filings caused by braking, which will lead to yellow tires, they should be used continuously, thus forming a vicious circle. Silicone lubricants are different, which can avoid yellowing. However, it should be noted that because it also has lubrication function, it can only be used on the side of the tire that does not touch the ground, but not on the front.
