Nanchang Hongbao Repair Center invested a lot of money to introduce CNC dynamic wire drawing equipment and technology from Germany, specializing in the repair of aluminum alloy wheels, especially the threaded wire drawing aluminum alloy wheels that no one can repair in Jiangxi blank market, which can be repaired to the original factory standard. Nanchang Hongbao Repair Center teaches you how to maintain car wheels: Maintenance methods: Car wheels have won the favor of more and more private car owners for their beauty, safety and comfort. Almost all new models use aluminum alloy wheels, and many car owners have replaced the original steel wheels with aluminum alloy wheels. This paper introduces the maintenance method of aluminum alloy hub: when the hub is stained with asphalt that is difficult to remove, if the general cleaning agent doesn't work, you can try to remove it with a brush, but don't use a hard brush, especially an iron brush, so as not to damage the surface of the hub. Here, I would like to introduce a folk prescription for removing asphalt to private car owners: it is to use "activated oil" to rub it, which can achieve unexpected results. Let's try it. When the temperature of the hub is high, let it cool naturally before cleaning, and never use cold water to clean it. Otherwise, the aluminum alloy wheel hub will be damaged and even the brake disc will be deformed, which will affect the braking effect. In addition, cleaning aluminum alloy wheel hub with cleaning agent at high temperature will cause chemical reaction on the wheel hub surface, lose luster and affect the appearance.
