Black spots on car paint can result from the following causes: The paint film is contaminated by pollutants and harmful substances in the air, which adhere to the surface. The pigments in the paint used are not resistant to acids or alkalis or may develop mold. The paint film may soften, become sticky, or release foreign substances during use. Asphalt Treatment: If the black spots are asphalt adhered to the paint, they can be cleaned using a tar remover. Remember to wear gloves when using a tar remover. Bird Droppings and Other Impurities: If the black spots are caused by substances like bird droppings, they can be soaked with car wash soap or glass cleaner. Once softened, they can be easily removed.

I've driven for half my life and seen too many cases of black spots on car paint. Those tiny black specks are usually caused by iron particles or industrial pollutants adhering to the surface—metal particles oxidizing and turning black in the air, or tree sap and bird droppings drying up when parked under trees. If not treated promptly, these spots can corrode the paint, causing increasing damage. I've used professional cleaners to spray and gently wipe them off—never use hard brushes that might scratch the paint. When parking, I always choose open areas, avoiding spots under trees or near industrial zones. Frequent washing helps reduce buildup. Remember to maintain your car regularly: give it a simple wipe-down weekly and a deep clean monthly. This keeps the paint glossy and durable, saving you money on major repairs.

When I first bought the car, I was super excited, but black spots appearing on the paint really dampened my mood. I looked it up and found it might be an environmental issue—the car was often parked by the roadside in a park, where tree sap and dust combined to leave spots. DIY cleaning with warm water and neutral car wash solution easily removed them, and later I found a clay bar worked even better. Now, I avoid parking in areas with lots of birds or pollution and wash the car regularly to prevent black spots. My car stays shiny, and I feel a great sense of achievement doing it myself.

Black spots on car paint are often caused by iron particle contamination or organic residue. Try using a car wash detergent to treat them; if they feel rough to the touch, it might be tree sap—wipe with soapy water. Parking in a safe area can reduce these issues.
