I washed the truck yesterday and used the new bottle of All Wheel Cleaner. I followed the directions: Sprayed, let sit for a few seconds, used a brush to agitate, then I thoroughly rinsed the wheels. When I was finished and pulled the truck into the garage, I saw this...

And there were matching stains under all four wheels, why?
What did I do wrong? Any ideas?
I will try to get it off with my pressure washer, but I can't really do that every time I was the car.
