Washing your own car is satisfying, and done well, it’s one of the best things you can do for your paint. Done badly, it’s also the most common cause of swirl marks. These are the mistakes we see most often.
1. Using dish soap
Dishwashing liquid is designed to cut grease, which means it also strips wax and sealant from your paint and can dry out rubber seals. Use a dedicated, pH-balanced car shampoo instead.
2. Washing in direct sunlight
Hot panels cause shampoo and water to dry before you can rinse them, leaving spots and streaks. Wash early in the morning, late in the afternoon or in the shade.
3. Using a single bucket
With one bucket, every time you reload your mitt you pick up the grit you just removed. The two-bucket method, with one bucket of shampoo and one of clean rinse water, keeps that grit away from the paint.
4. Skipping the pre-wash
Rubbing a mitt straight onto a dirty car grinds grit into the clear coat. Rinse thoroughly first, or use a snow foam to soften and lift dirt before you touch the paint.
5. Washing the wheels last
Wheels are the dirtiest part of the car. Clean them first, with separate brushes and a separate bucket, so brake dust doesn’t splash onto freshly washed paint.
6. Drying with the wrong towel
Old bath towels and chamois can drag trapped grit across the surface. A large, plush microfibre drying towel is safer and more absorbent.
7. Dropping the mitt and carrying on
If your wash mitt touches the ground, it’s no longer safe to use on the paint until it has been thoroughly rinsed. Keep a spare mitt on hand.
The quick checklist
- pH-balanced shampoo
- Two buckets, ideally with grit guards
- Wheels first
- Pre-rinse or snow foam
- Work top-down, in the shade
- Plush microfibre for drying
