There's nothing worse than waking up to find your car covered in splattered spray paint, likely caused by some mischievous kids. Don't panic! There are several ways to remove spray paint from your vehicle, and the most effective methods involve using nail polish remover, clay bars for removing paint dust, and carnauba wax.
Steps
Use Acetone or Nail Polish Remover

Purchase a bottle of acetone or nail polish remover that contains acetone. If acetone is not available, you can use a nail polish remover solution. Nail polish remover is designed to remove the outer layer of your nails, which is essential for dealing with spray paint on your car. Any brand will work, but the higher the acetone concentration, the better.

Pour acetone or nail polish remover onto a cloth. Choose a soft cotton fabric or a microfiber towel to avoid scratching the glossy or colored paint on your car. The cloth should always remain wet, so you'll need to add more acetone or nail polish remover when the cloth begins to dry out.
- Wear gloves to protect your hands from acetone or nail polish remover, and any splashes of paint.

Gently wipe the spray paint stains. Use circular motions to remove the spray paint from your car. Be gentle to avoid damaging the car's glossy or colored paint while wiping away the spray. The paint will transfer to the cloth, so it's important to change the cloth regularly.

Wash your car after removing the spray paint. It's essential to wash your car thoroughly after cleaning off the spray paint. Pay special attention to the areas with spray paint stains to ensure all traces of paint and acetone or nail polish remover are removed.
Use clay bars to remove paint dust

Wash and dry your car. This step is crucial to clean any dirt before using the clay bar. You can wash your car by hand or take it to an automatic car wash. Hot water and soap can also help remove fresh spray paint stains.

Purchase clay bar for paint dust removal. A clay bar is a polymer compound that can remove impurities from your car’s paint without scratching or damaging the surface. There are various types of clay bars available, such as Detailer’s Pride Clay. Another option is the Meguiar’s Smooth Surface Clay Kit, which includes spray lubricant (that can be used as a lubricant for the clay), wax, and a microfiber towel.

Prepare the clay. You only need a small, flat piece of clay about the size of your palm. You can cut the new clay bar in half to use it. Place the clay in a resealable plastic bag and submerge it in warm water to soften it. Knead half of the clay bar in your hands and shape it into a flat, pancake-like piece.

Spray lubricant. The lubricant allows the clay bar to glide over the paint surface without sticking. Shake the spray bottle and apply it to both the clay bar and the paint stains on your car. Use plenty of lubricant so the clay bar doesn’t stick to the car surface.

Rub the clay bar over the spray paint stains. Hold the clay bar in your palm, avoiding your fingers. Rub it back and forth over the paint stains, similar to how you would apply soap to your skin. Continue rubbing the spray paint stains until they're clean.
- When the clay bar gets dirty, fold it and knead it back into a clean shape.

Wipe off any remaining residue. Use a microfiber cloth to wipe off the clay residue from your car. Gently rub the treated area to ensure it’s clean.

Polish the car. The clay bar process will remove the old wax layer from your car's surface, so it's essential to reapply wax to protect and restore the shine of the paint. Use a waxing tool or a sponge included with the wax to apply it to the car's surface using circular motions.
Use carnauba wax.

Purchase liquid carnauba wax. Products like Butter Wet Carnauba Wax contain carnauba oil, which can dissolve spray paint. This type of wax won't scratch or damage the car's clear coat, but will help remove the spray paint. You can buy liquid carnauba wax from auto parts stores or online.

Pour the wax onto a sponge. Apply a generous amount of wax onto the sponge or a soft cloth. Reapply more wax during the cleaning process if necessary, and don't worry about using too much, as you'll need enough to break down the paint.

Scrub the spray paint stains with the sponge. Rub the sponge on the affected area with firm pressure and in circular motions. Make sure to cover the entire spray paint stain and any remaining paint droplets on the surface of the car. Replace the sponge or turn it over once one side is filled with paint.

Wipe off the wax. After removing the spray paint stains, you need to clean off any wax residue from the car's surface. Use a microfiber cloth and gently rub in small circular motions over the wax-covered area.
Advice
- Remove spray paint as soon as possible, as it becomes harder to clean the longer it stays under the sun.
- If the car windows are also affected by spray paint, you can easily clean them with acetone and a razor blade.
Warning
- Avoid using abrasive products like cleaning compounds, as they can damage your car's paint job.
- Regardless of the method you choose, always test it first on an inconspicuous area of the car.
