How Do Swirl Marks Occur?

[Rosalie]

When washing or waxing the car, if one fails to notice that the cleaning tools or the car's surface contain dust, fine sand, or other particles. Washing or waxing is typically done in circular motions, which can cause fine spiral-shaped scratches on the car's paint. Under light exposure, these scratches appear as circular patterns resembling the rays of the sun, hence commonly referred to as swirl marks.
