But if you look closer – or let owner Daniel Birkhofer open a manhole cover – you quickly realize: there’s significantly more technology, passion, and sustainability here than anywhere else.

Hidden beneath the paving stones is, among other things, a 50,000-liter cistern that collects rainwater. And that’s a real advantage for car enthusiasts: rainwater is soft, lime-free, and therefore ideal for a gentle, spot-free wash – perfect for sensitive paintwork, chrome, and classic car treasures. The wash water is then collected, biologically treated, and reused repeatedly. Clean for the car, clean for the environment.

In the biological treatment plant, oxygen and beneficial bacteria do the work. They arrive naturally – directly with the dirt from the vehicles. Small foam cubes provide them with a large surface area so they can clean effectively. High-tech, yet surprisingly natural. Energy? Clean Park Eco generates it itself. Photovoltaics, solar thermal energy, heat pumps, geothermal energy, heat and battery storage ensure that everything runs smoothly. From warm wash water to underfloor heating in the bays. Completely without fossil fuels. The result: first-class care with maximum resource conservation. In addition, there’s a dog wash, professional vehicle detailing, a shop for care products, and even seminars on preserving value. No wonder experts from all over the world pilgrimage to Dettenhausen.
