Have you ever noticed the spiderweb-looking swirls on the hood of your car? Circular scratch formations called swirl marks are super common and unfortunately can make beautiful paint pop a bit less.
The good news is you can remove swirl marks and prevent them in the future in a few steps.
So what exactly are swirl marks?
Swirl marks are tiny circular micro-scratches that get etched into a vehicle’s clear coat usually as a result of improper hand washing.
Your car’s clear coat may look unblemished if wet or at night, but in direct sunlight, these circular marks are obvious; swirl marks are especially noticeable on dark-colored vehicles.
What causes swirl marks
Swirl marks usually occur when debris like tiny rock particles are forced into the clear coat by a soap applicator.
If a wash mitt is dirty or not enough lubrication is used, hard particles can easily act as tiny knives cutting through your vehicle’s protective layer. Not good.
Small debris will typically create a shallow and jagged or V-shaped abrasion into the clear coat rather than a deep scratch. To the human eye, swirl marks can be hard to see. When sunlight reflects off of these jagged edges and bounces the light to the surface, our eyes can then perceive the scratch.
At a microscopic level, this diagram illustrates what happens when small particles or objects abrade the clear coat. While swirl marks are pretty shallow, when debris cuts beyond the clear coat layer, paint is permanently removed.
How to remove swirl marks
To remove swirl marks, we recommend using a lightly abrasive car polish with a dual-action polisher.
Polish can remove swirl marks, and these products work to sand down jagged peaks in the clear coat layer.

Tips to prevent swirl marks on your car
You can prevent swirl marks using proper technique, pre-washing, and working clean!
View our post on how to safely hand wash your car like a pro if you suspect you’ve been leaving swirl marks. I break down a safe step-by-step process I use every time I wash—from washing to drying.
Very faint swirl marks are not the end of the world, and can sometimes occur outside of the wash process. The good news is they’re not permanent and can be removed with basic paint correction.
1. Always pre-treat to reduce the risk of scratching paint
Many professional detailers apply foam to pre-treat dirty cars, which helps remove dirt particles that lead to swirl marks. Car foam or snow foam is a type of pre-treatment soap created using a foam cannon and a pressure washer. Snow foam helps trap dirt on contact, so it’s easy to rinse off.
2. Use enough soap for proper lubrication
Make sure your wash mitt has enough suds to protect against grit or dirt on your vehicle. If you work in the heat, suds can evaporate quickly, causing the wash mitt to drag instead of glide across the clear coat.
Standard car soap and concentrated car shampoo normally contain special lubricants that help reduce the potential for scratching.
Don’t use dish soap to wash your car. Not only will it strip off previously-applied wax, dish soap creates fluffy and dry foam—which won’t properly lubricate a wash mitt.
3. Avoid friction and avoid circular motions
We recommend side-to-side or up-and-down motions when hand washing because circular motions generate more friction.
Since the idea is to slide the dirty suds off your vehicle, never bare down or scrub any painted section of your vehicle.
It’s okay to create friction with a car polisher because you’re removing a scratch on an already clean panel.
4. Add a layer of protection to your clear coat
We always recommend applying a protective layer like a ceramic coating to help protect your vehicle from any kind of paint damage. Paint protection products won’t completely eliminate your swirl mark risk, but they can add a tiny layer of protection. Some ‘self-cleaning’ ceramic coatings also make it extremely difficult for dirt or other particles to stick to your paint.
