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 most environmentally friendly option because these facilities typically have systems in place to manage and recycle water and soap. They often filter and treat wastewater before it is released, minimizing pollution. Washing a car in a carpark or on an open road can lead to runoff that carries soap and dirt into storm drains, which may harm local water sources and wildlife. German regulations emphasize the importance of protecting the environment, particularly water quality, thus promoting the use of professional car washes for car cleaning.
