Top Causes of Swirl Marks (and How to Avoid Them)
Swirl marks are the number one complaint of car owners with dark paint. They’re those light, spiderweb-like scratches you see under the sun or shop lights. But what actually causes them, and how can you stop them from appearing? This guide breaks down the top causes of swirl marks and the exact steps to prevent them.
What Are Swirl Marks?
Swirl marks are micro-scratches in your car’s clear coat. They scatter light in a circular pattern, making them look like spiderwebs. While they don’t penetrate through the clear coat, they reduce gloss and make paint look older than it is.
Top Causes of Swirl Marks
1. Improper Washing Techniques
Using dirty sponges, old cotton towels, or dragging dirt across paint is the number one cause of swirls. Every time you touch your car without proper lubrication, you risk scratching the clear coat.
2. Automatic Car Washes
Brush-style car washes are swirl machines. The brushes are filled with grit from hundreds of cars before yours, and they grind that dirt right into your paint.
3. Dry Wiping
Many people grab a dry rag or towel to wipe dust or bird droppings. This is a recipe for scratches since the dirt is dragged directly across the surface without lubrication.
4. Low-Quality Towels
Old bath towels, t-shirts, and cheap microfiber towels often have rough fibers and edges that scratch paint instead of protecting it.
5. Contaminants on Paint
If your car isn’t clayed regularly, bonded contaminants like brake dust and sap create resistance when wiping, causing scratches.
6. Improper Drying
Dragging a chamois or cotton towel across wet paint is another common cause of swirls. The wrong drying method does just as much damage as bad washing.

Real-World Example
A customer with a black SUV noticed heavy swirls after frequent visits to a gas station automatic wash. After switching to hand washing with The Super Soaper and drying with the Massive Drying Towel, swirl marks stopped forming. With a single round of polishing using Picture Perfect Polish, the SUV regained a deep, swirl-free shine.
Extra Q&A on Swirl Marks
Q: Can I remove swirl marks without polishing?
A: No, polishing is the only permanent fix. Wax and glaze can fill swirls temporarily but won’t remove them.
Q: Do microfiber towels completely prevent swirls?
A: They reduce the risk significantly, but improper use (like dragging grit-filled towels) can still cause swirls.
Q: Is claying safe for paint?
A: Yes, when done with lubrication. Claying removes bonded contaminants that could otherwise cause scratches during washing or drying.
