How to Remove Black Spots from White Car Paint?

Normal car washing, clean and dry the white car; soak the towel and gently squeeze it out. Apply the wax paste onto the towel. Do not pour too much. Use the towel soaked with essential balm to gently wipe the spots on the car. Wipe once, then again after 2 minutes, until the spots disappear. Methods to prevent white car paint spots include: frequent car washing, waxing, glazing, coating, and crystal coating. Do not park the car under trees, as many trees secrete sticky substances that adhere to the car and are difficult to remove. Wash the car immediately after rain, as most spots on the car body are caused by acidic substances in rainwater.
As a white car owner, I always keep iron remover and clay bar in my garage. Whenever I notice small black spots after washing the car, I first spray water on the paint with a spray bottle, then pour a whole capful onto a sponge and apply it. Wait two or three minutes, and the rust stains will turn purple and flow down. For stubborn tar spots, I spray some tar remover and wipe in circles with a soft cloth—never use anything hard to scrape them off. After treatment, I must rinse with clean water again. If the paint has already been corroded into small pits, I need to find a professional for polishing, as doing it myself could damage the clear coat. Finally, I wax the entire car for protection, making it less likely to attract dirt the next time it rains.
I've noticed many small black spots on white cars, mostly caused by brake pad iron dust sticking to the paint and rusting. Prepare a bottle of automotive-specific iron remover, spray it on the dry paint after washing the car, wait five minutes for it to react, then rinse it off. For tree resin or tar spots, I recommend using an orange oil tar remover—spray it on a slightly damp microfiber cloth and gently wipe. For areas with particularly dense black spots, using a clay bar while rinsing with water is more effective. After treatment, remember to dry promptly and apply car wax, otherwise the paint may become dull. When parking, try to avoid spots under trees or near restaurant exhaust vents.
