You want to wash your car. Where should you do this in the interests of environmental protection?

Washing your car at a carwash is the correct choice for environmental protection. Carwashes are required to have systems in place that collect and treat dirty water, oils, and detergents so they do not enter the environment uncontrolled. Washing your car in a carpark or on an open road can cause harmful substances to flow directly into the soil or sewer system, polluting water sources. That's why, according to German traffic and environmental regulations, carwashes are the environmentally responsible place for cleaning vehicles. This rule helps protect groundwater and the ecosystem.
