How to fix bird droppings on car paint

Updated February 21, 2017

Car enthusiasts can spend many hours every week shining, waxing and polishing their cars, only to see the carefully cultivated look marred by the "souvenirs" of a few birds. Bird droppings contain uric acid, the same chemical composition as ammonia. If left untreated the marks left by bird droppings can ruin a car's paint.

Remove the bird droppings and spray some mist on the affected area if the bird droppings haven't been on the car for more than half an hour. Rub a coat of car wax or car sealant on the affected area with a soft cloth if no stains or marks remain from the bird droppings. Purchase car wax or car sealant at an auto supply shop or an auto centre.

Rub a scrub sponge with car wash shampoo over the area with the bird droppings if the droppings have been on the car's paint for more than half an hour. Apply a car polish and glaze with a soft cloth and finish by rubbing in car wax or sealant. The spot or stain will still be noticeable, but polishing and glazing can reduce the defect's visibility.

Remove a layer of the car's paint if, after wiping off the bird dropping, the car's surface exhibits signs of staining or a pitted or etched surface. Remove the paint by abrading the top coat or paint on the car with abrasive polish applied to a compounding pad fitted on a circular polisher. Once the polisher removes the pit or stain along with the top paint coat, apply a new coat of paint to that entire area of the car.

Purchase abrasive car polish, compounding pads and car paint at an auto supply store or an auto centre. Rent a professional circular polisher from an auto supply shop or a bodyworks garage.

Repeat the polish, glaze and wax procedure through the years as necessary, as their effect in hiding the defect will not hide the defect from the bird droppings permanently.
