Which do you think is the greener alternative, washing your car at home or taking it to a car wash? You might say that doing all your own car washing is greener because you can control the amount of water you use and you won’t be using any other equipment apart from a hose, rags, and brushes to clean your car. But actually, you might be harming rivers and oceans because of the run-off from your home car washing. Car washes, on the other hand, are required to treat their wastewater, plus they actually use less water! If you still want to home wash though, Earth 911 has a list of ways that you can make it more water-saving and eco-friendly.
