Black scuff marks are common on a car's exterior, and are especially noticeable if you have a light-coloured car. Most often, these marks appear from bumping your car's door when you get out of the car or casually pushing the door shut from the outside with your shoe. Body shops charge a lot of money to buff out these marks, but you can do it yourself in just a few easy steps.
Pour a small amount of detergent in the bucket, add water and mix well. Wet your sponge.
Scrub the scuff marks to remove any loose dirt or debris.
Wet the sandpaper and gently sand the scuff mark. Avoid applying too much pressure because that could damage the car's finish. Sand until the scuff mark is no longer visible.
Dampen your sponge, and apply a small amount of polish compound. Rub the area until the finish is shiny.
Wax and buff the area.
