Your car is clean but what about the water? The best way to minimize the effect washing your car has on the environment is to use a commercial car wash. This is because most locations reuse wash water several times before sending it to a treatment plant. However, if you choose to wash your car at home or on the street, these are some things that you can do to minimize the water quality impact:
- Use biodegradable, phosphate-free, water-based cleaners only.
- Minimize water usage. Use a spray gun with flow restriction to minimize water volume and runoff.
- Wash on an area that absorbs water, such as gravel, or grass. This can filter water before it enters groundwater, storm drains, or creeks. Avoid washing cars on concrete or asphalt pavement unless it drains into a vegetated area.
- Only let wash water soak into the ground as long as you are using biodegradable, phosphate-free cleaners.
- When planning a car wash fundraiser, try developing a partnership with a commercial car wash facility, or use a safe location.
- Always empty wash buckets into sinks or toilets.
Car washing is a serious contributor to storm water pollution that could contaminate our streams, rivers and lakes.
