I would spend the 30 minutes to wash the exterior yourself.
1. Wash the wheels first make sure they are not hot (I use P21S Gel expensive but idiot proof)
2. wash the car with a good car wash (not dishwashing detergent), start by rinsing the car off from the top to bottom, then get your mitts sudded up and start washing from the top to bottom, I would wash the your X in a side to side motion, not circular. Take the nozzle off the hose and rinse the car off from the top to the bottom again.
2. Dry it with a waterblade, electric blower, microfiber waffle weave towel (again top to bottom)
3. Clean the windows
4. Dress the tires if you like
I think your done, help me if I missed anything.
