Excellent Carwash Amsterdam – wasstraat & wasboxen (Sloten)

Used the washbox for the first time and it was a good experience overall. There are two payment options: card payments in multiples of €2.50, and coin payments. A €1 coin gives you around 100 seconds of washing time, during which you can use any mode. Unfortunately, the system doesn’t show the remaining time—only a percentage of credit used—so the actual duration may vary depending on calibration. The soap felt very diluted, which is why I’m giving it 4 stars. Other than that, it’s a very good washbox.
