How to Remove Uncleanable Yellow Stains from Car Paint?

[RobertFitz]

Yellow stains that cannot be wiped off from car paint are caused by iron particles in the air adhering to the car's surface and oxidizing. Here are methods to remove yellow stains: 1. Use a rust remover: Spray a car paint rust remover and wipe it off. Regular car washing and protective measures such as waxing, sealing, coating, or crystal coating can help. Avoid parking under trees as many trees secrete sap, which is difficult to remove. Washing the car immediately after rain can effectively prevent yellow spots on the car paint. 2. Polishing: Use microcrystalline polishing wax. Polishing is a process that removes unevenness from the paint surface to achieve a smoother surface and higher reflectivity. This requires removing a portion of the paint surface to achieve the desired effect.
