The classic stereotype about Germans is that they are very fastidious with a preference towards making things efficient, clean and well engineered. Stuttgart, home to Porsche and Mercedes-Benz , has another business in the city could show off a little of the country's perceived national character: Mr. Wash. The world's largest carwash, Mr. Wash is so spectacular that its arching two-story business (pictured above) is highlighted in a new video from The Wall Street Journal.

Mr. Wash doesn't really do anything special when it comes to cleaning vehicles; it just does its job on a massively industrial scale. At full capacity, the business can wash 400 vehicles an hour, or about half a million a year.

Prices seem reasonable, too, with a range between 6 and 20 euros ($7.50-$26) depending on what services customers want. On the bottom level there are even vacuums and cleaning machines for owners to use if they are real neat freaks. The Stuttgart location of Mr. Wash has a gas station, and it can also do oil changes. Check out the video to see how Germans keep their cars sparkling clean.
