I am skeptical on the "just spray on and rinse off" claims. I haven't washed my rear tire since last spring. It didn't look chrome anymore. I decided to try this to see if it does was it claims. I sprayed it on my rear chrome wheel, i really soaked it good, and it says in 1-2 mins, rinse with cool water. By the time I hooked up the hose, and looked at the wheel, it was amazing. I rinsed it twice to make sure I got all the chemical off and check it out. I didn't wipe a thing, just blew the water off with air hose. Great product for wheels that are pita to clean as the Chisel wheels are. This is for Chrome only.
