Most swirl marks come from washing, not driving. The dirt you wipe off ends up back on the mitt and gets dragged across the paint. The two-bucket method stops that.
- Pick the time. Wash in the shade when the paint is cool. Soap that dries on a hot hood leaves spots.
- Set up two buckets. Fill one with car wash soap and water and the other with plain water. A plastic screen at the bottom of each bucket helps keep dirt down. Use car wash soap, not dish soap, which can strip wax.
- Rinse first. Hose off loose dirt and mud from the top down.
- Do the wheels first, with their own tools. Brake dust and road grime are rough. Use a separate brush and mitt for the wheels so that grit never touches the paint.
- Wash from top to bottom. Dip the mitt in the soap, wash one panel, then rinse the mitt in the plain water before it goes back in the soap. The lower sides are the dirtiest, so save them for last.
- Dry gently. Use a clean, soft microfiber towel and blot or pull it lightly across the paint. A leaf blower helps push water out of mirrors and trim.
- Make it a two-person job. One person washes while the other rinses and changes the water when it gets cloudy. Kids usually like the rinsing part.
