This step is important to remove surface dirt before applying the clay. You can wash your car by hand, or take it through an automatic car wash. If the spray paint is very fresh, the hot water and soap may even remove some of the paint. Detailing clay is a polymer abrasive which will remove anything sitting on top of the paint on your car, without scratching or damaging the surface.

Another option is Meguiar’s Smooth Surface Clay Kit, which includes detailing spray (which you would use as a lubricant for the clay), as well as wax and a microfiber cloth.

Shake the lubricant, then spray it onto the clay and also onto the paint on your car. Use an ample amount so that your clay won’t smudge onto the car. Clay lubricant should be available at your local auto parts store. Hold the clay in your hand so that your fingertips are not covered by the clay -- you want it to be a little lower in your palm. Rub the clay back and forth with a firm pressure, like you would rub a bar of soap over your skin. Keep rubbing the clay over the spray paint until the paint is removed. When your clay becomes covered in contaminants, fold it over and re-knead it to form a clean patty. Use a microfiber cloth to wipe the clay residue off the car.
