Most paint swirls are caused by improper detailing techniques. For example, when you wash your vehicle, dirt and sand get trapped in the sponge or mitt. The first time you re-wet your sponge in the bucket, some of the abrasive particles will come off the sponge into the water. Subsequent dips in the bucket will re-contaminate your sponge.
