I enjoy hand washing my cars. However the first time I tried it at home I found that our outside water (since it doesn't go through the softener) leaves a mess of hard water spots on the car. So I usually go through the touch-free car washes but I'd really rather do it myself. I've seen "spot-free" car wash products but would they eliminate hard water type spots? I actually tried a little spot using water and spot-free dish soap but that didn't help.
