Car Detailing Mistakes That Cause Swirl Marks and Scratches
The habits that scratch paint, and how to wash and dry more safely.
What causes swirl marks on a car?
Swirl marks are fine scratches in the clear coat, usually from dirty wash mitts, dry wiping, automatic brush washes and rough drying towels. They show up as circular marks in direct sun. Safer washing prevents most of them, and paint correction removes light ones.
Common mistakes
| Mistake | Why it scratches | Do this instead |
|---|---|---|
| Washing with one bucket and a dirty sponge | Drags grit across the paint | Use two buckets, or rinse the mitt often, and a clean microfiber mitt |
| Wiping dust or ash dry | Grinds grit into the clear coat | Rinse first, or use a quick detailer with plenty of lubrication |
| Using dish soap | Strips wax and sealant and dries out trim | Use a pH-neutral car shampoo |
| Washing in direct sun | Soap dries and leaves spots | Wash in the shade |
| Drying with a bath towel or old rag | Rough fibers scratch | Use a clean microfiber drying towel |
| Using brush-style automatic washes often | Brushes hold grit from other cars | Choose touchless or hand wash |
| Dropping a towel and reusing it | Picks up grit from the ground | Replace it with a clean towel |
How to wash more safely
- Rinse the car thoroughly first to remove loose grit.
- Wash from the top down with a clean mitt, and rinse the mitt often.
- Wash wheels with separate tools.
- Rinse and dry with a clean microfiber towel.
Fixing swirls
Light swirls can be polished out, and deeper scratches may need paint correction or may not be fully removable. See our paint correction page. A ceramic coating helps prevent new ones.
In Spokane
Winter road grit makes gentle washing even more important, since dirt builds up on the car for weeks. Rinse well before you touch the paint. Our exterior detailing uses a safe wash method.
