How to Remove Small Black Spots on a White Car?

Methods for removing black spots on a white car are as follows: 1. Asphalt: If the black spots are asphalt attached to the car paint, they can be cleaned using tar remover. Remember to wear gloves when using tar remover. 2. Bird droppings and other impurities: If you frequently park under trees, your car will inevitably be attacked by bird droppings or tree sap. If the black spots are substances like bird droppings, you can soak them with car wash liquid or glass cleaner, and they can be easily removed after softening. 3. Iron particles: If the black spots on the white car paint are dense iron particles, the above cleaners will not work. Only specialized clay bars or detailing clay can be used to slowly grind them off after washing the car body.

My own white car often gets these annoying little black spots, especially after rain or when parked under trees for a long time. I usually start by thoroughly rinsing the car body with car wash soap to soften the stains before tackling them. For a small number of black spots, I use detailing clay with lubricant to gently rub them away, applying light pressure like when applying a screen protector to a phone, while constantly folding the clay to avoid recontamination. For particularly stubborn spots, I spray tar remover, wait two minutes, and then wipe, being careful to avoid plastic parts to prevent whitening. It's crucial to apply wax immediately after treatment to seal the surface, making it harder for stains to adhere next time. The whole process takes about half an hour, and doing it myself saves hundreds in detailing fees.

The key to dealing with black spots on white cars lies in early prevention and regular maintenance. My experience is to perform a full-body decontamination once a month, using a dedicated iron particle remover combined with clay bar treatment. For daily parking, try to avoid shaded areas under trees and construction sites, and rinse promptly after rain. If new black spots are discovered, address them immediately to prevent oxidation penetration. Nowadays, I apply a nano-coating on the car's paint surface—though the initial cost is higher, it makes later maintenance much easier. When washing the car, switch to a soft sponge to reduce friction damage. By sticking to these habits, the issue of black spots becomes much less frequent.

These minor stains are mainly caused by three types of contaminants: tar splashes, metal iron particles, or insect residue. Tar spots can be dissolved with tar remover; iron particles require a dedicated iron remover, which turns purple upon application; stubborn insect stains should be treated with insect remover. Always perform a spot test first, ensuring the cleaner is left on for no more than three minutes, and gently wipe in a circular motion. Never use fingernails or hard objects to scrape, as this will definitely leave scratches. After treatment, thoroughly rinse off any residual chemicals and promptly apply wax or sealant to isolate the surface from air.
