I've always used the wand at a car wash. Been doing it for years that way with no problems, I just make sure and use STATIC pressure only around electrical stuff, otherwise lay into it and it always comes out like brand new again. I also do this with all the cars I work on as a side job. Helps bring people back when you go the extra mile and spend $5 at the car wash for them. ...."oh Wow, it hasn't been like that since I first bought it!"
