A pressure washer is not a good idea as they usually have high enough pressure to damage gaskets and blow water right past rubber seals into the engine. I have witnessed motorcycle engines fail because the owner liked to keep them spotless with a pressure washer after each ride. A car wash is generally nowhere near the same pressure and poses a lot less risk. Just use a little common sense and there isn't much on a 300d that you will damage with a car wash.
