How do I clean wildfire ash off my car?

Rinse the ash off with plenty of water before you touch the paint. Never wipe it dry, because ash is gritty and can scratch the clear coat. Then wash with a pH-neutral car shampoo and a clean microfiber mitt.

Clean the outside

  1. Wait until ash has stopped falling and the car is cool and in the shade.
  2. Rinse from the roof down with a gentle but steady flow of water. Let the water carry the ash off.
  3. Wash with a pH-neutral car shampoo, using a clean wash mitt and rinsing it often.
  4. Rinse again, then dry with a clean microfiber towel.
  5. Check the glass, wipers and the cowl area under the windshield, where ash collects.

Clean the inside

Ash and smoke particles get into the cabin through the vents and on shoes and clothes. Vacuum the carpet and seats, wipe hard surfaces with a damp microfiber, and clean the vents with a soft brush. A fresh cabin air filter helps keep the air inside clean. If the car still smells of smoke after cleaning, the odor is likely in the fabric, headliner and vents, and it needs a deeper treatment. See our smoke odor removal service.

In Spokane

Smoke seasons in the Inland Northwest usually come in late summer. The Spokane Regional Clean Air Agency posts current air quality, which is useful for deciding when to drive with windows closed and the vents on recirculate. If heavy ash settled on the car, rinse it before the next rain turns it into a film.

Questions

Will ash damage my paint?
Left on, ash can hold moisture and mix with rain into a residue. Wiping it dry is the bigger risk because it scratches. Rinse first.
Is a regular automatic car wash fine for ash?
A touchless wash is gentler than brushes. Rinsing at home first is still the safest start.
Should I replace the cabin air filter after smoke?
If you drove through heavy smoke, a new filter is a sensible low-cost step.
