Are you crazy, a power washer? Lol. Dude I live in South Florida and I wash my car everyday because I like it to look spotless. Why would I need to wash my car with a pressure washer? All roads are beautiful here. We never get snow, so no salt on the roads. I do not off-road or even go on the beach with the ST. It is not allowed here. 10 to 15 minutes max is all it takes to keep her looking showroom on a daily basis, and that's including detailing my wheels quickly with soap and water and some tire shine. I have it down to a science. Waxing and clay bar on a Sunday takes about 2 hours max with McGuire's clay bar 2 system and quick detailing spray and a coat of meguiar's quality wax. My ST is spotless all the time and is never really gets that dirty (I never said it did), just Dusty or water spots from the well water used in the sprinklers that overspray at random areas around town. When I take the 4-Hour Drive between my homes I have to use the bug spray on front fascia, grill and bumper when I get to the other side in order to remove the dead carcasses that I encountered along the way. I do it within a few minutes of getting to my destination. Other than that easy peasy.
If it takes you 2 to 3 hours to wash your car I must be missing something or you must move in reverse or do it every 6 months then I can understand why it would take so long to get road crime and debris off the vehicle. If you would detail more it would take a lot less time and as with anything you would become more efficient at it.
Ya, you are missing something. We don't all live in the sunshine state, retired, with ample free time to wash our vehicles each time they get a water spot.
The world is a lot more diverse than just what you get in Florida.
For instance: 8 months out of the year here, a trip around the block to drop the kids at daycare could result in an inch of snow/slush/salt/mud buildup on the vehicle.
Even when it is dry, out roads are rarely clean like yours are.
So why a carwash? Because the majority of us have better things to do with our time.
