Repair methods for wheel hubs

When there are difficult to remove stains on the surface of the wheel hub, professional cleaning agents should be used. These cleaning agents can often gently and effectively remove stains, reducing damage to the aluminum alloy surface. In addition, the wheel hub itself has a layer of metal protective film, so special attention should be paid not to use paint brighteners or other abrasive materials during cleaning. Be careful while driving to avoid scratching and causing "hard damage" to the wheel hub. Once there are scratches or deformations, they should be repaired and repainted as soon as possible. So how to repair scratches? There are six specific steps for repairing: the first step is to check the scars. If there is no damage to the inner side of the wheel hub, it can be easily repaired by using paint diluent to wipe the area around the scars and remove dirt; The second step is that the deepest part of the scratch is difficult to remove dirt and can be thoroughly cleaned with a toothpick; Step 3: To prevent accidental painting of unrelated parts, carefully apply adhesive tape around the scar area; Step four, tidy up the brush tip and apply decorative paint. Step five, after coating, wait for it to completely dry and use water-resistant paper dipped in soapy water to apply it, making the surface smooth; Step six, after wiping with water-resistant paper, use a mixture to create a shiny finish, and then apply wax. If you encounter deeper scars, the key is to observe whether the metal surface is exposed. If the metal surface is not visible, it will not rust and you can focus on applying decorative paint. Use a pen tip to place it bit by bit, and then wait for the paint to completely dry. To avoid such a phenomenon, the wheels of the car should be washed frequently at the beginning of use. Vehicles driven every day should wash the wheels at least once a week. First, wet them with water, then use a cleaning agent to sponge them, and finally rinse them with plenty of water. Daily maintenance is also essential. When the hub temperature is high, it should be allowed to cool naturally before cleaning, and cold water should not be used for cleaning; Otherwise, it will damage the aluminum alloy wheels and even deform the brake disc, affecting the braking effect. In addition, cleaning aluminum alloy wheels with cleaning agents at high temperatures can cause chemical reactions on the surface of the wheels, resulting in loss of luster and affecting their appearance. When there is difficult to remove asphalt on the wheel hub, if ordinary cleaning agents are ineffective, a brush can be used to try to remove it, but do not use a hard brush, especially an iron brush, to avoid damaging the surface of the wheel hub. An expert has introduced a folk remedy for removing asphalt: using medicinal "active oil" to apply and rub can achieve unexpected results. Car owners may want to give it a try. In addition, when the vehicle is located near the seaside, the wheels should be cleaned frequently to avoid salt corrosion on the aluminum surface
