I'm a college student and am going to start detailing cars on the weekend. I will have either some Sonax Wheel Cleaner Plus, or 1z Colourtech for wheels that are really dirty. However, I'm looking for a RTU wheel cleaner for wheels that aren't as bad (ie Japanese and American cars). The reason it has to be RTU is because I cannot be in the dorm bathroom diluting chemicals lol! Right now I'm interested in the Mother's Foaming Wheel and Tire Cleaner because it is cost effective and available in a gallon size. I've heard it has great reviews. Also looking at the Griots Garage Green Wheel Cleaner and haven't heard much about it. Any recommendations would be appreciated.
