- Inspect the area where you store your vehicle.
Do you see any evidence of leaking fluids? Keep your vehicle in good working condition and clean up any oil drips or fluid spills.
- Wash your car at a commercial car wash or spray booth where water drains into a treatment line or wash it over a lawn or gravel drive where wash water infiltrates into the ground.
Avoid washing cars where cleaning products and wash water drain into storm drains or water bodies.
