Does anyone know where I can clean it and for how much?
I got a 2nd hand car and it needs good cleaning, especially from inside.
I go to this one but it has various branches around Zurich area:

It has a self service vacum service after the car wash and you pay for the amount of time you want to use the hoover. It comes with a doggy wash too..
There's also a good & cheap self service one opposite Letzipark on Hohlstrasse. Lots of Vacuum machine spaces & a 1 franc token lasts ages.
The one at Letzipark is called Stützliwösch and is part of a chain with some other branches in and around Zurich:

It's quite funny watching the young drivers lovingly cleaning their cars fridays as preparation for the weekend.
