There are wheel cleaning products on the market that claim to be spray-on, hose-off, no-touch wheel cleaners. If you've tested them like we have you've discovered they don't really get your wheels thoroughly clean. You still have to wipe the surface for a proper cleaning. Any cleaner that could work without wiping would be extremely harmful to the environment and to your eyes, skin and nose. Enjoy this fabulous cleaner knowing it's safe and it really works.
