If you’re dead-set on washing your car at home with the kids, here’s how to keep the impact at a minimum:
- Park on gravel or grass so soapy water soaks into the ground, becomes filtered and recharges groundwater.
- Avoid soaps with labels that say “harmful, danger or poison.”
- Turn off the hose when you’re not using the water. During a 15-minute car wash, you could use 150 gallons of water if there isn’t an automatic shut-off nozzle.
