Can Scratched Wheel Hubs Be Repaired?

Scratched wheel hubs can be repaired, either by yourself or at a repair shop. Methods for repairing wheel hubs: Carefully inspect whether the scratch extends to the inner side of the wheel hub. If it can't be simply patched, just use paint thinner to slowly wipe around the bruised area and remove dirt. If the scratch on the wheel is deep and the dirt next to the scratch is difficult to remove, then tools are needed—just a small toothpick can thoroughly clean it. Impact of wheel hub scratches: If the wheel hub is scratched and only the paint is damaged, replacement isn't necessary. Sometimes the scratched area may appear large and seem severe, but it still doesn't require replacement because the performance isn't affected—only the aesthetics are compromised.
