Advanced Auto carries RTU
Meguiars Non-Acid Wheel and Tire Cleaner in stores.
Or else if in a pinch, Super Clean is at Walmart as well as Purple Power. Dollar stores carry LAs Totally Awesome APC (I've never tried this one).
Honestly, most APCs and dedicated tire cleaners will do the job. I've used Tuf Shine tire cleaner before and I wasn't blown away by it. It simply cleaned the tire like any other APC. Same for the expensive Gyeon Tire Cleaner.
Just buy what's economical. I just bought a gallon of Megs Wheel and Tire cleaner online for $25. After researching, its one of the most economical in a gallon (designed for tire cleaning). I had been using Nanoskin Multi Clean APC and it did a great job on tires @ 2:1 ratio. It used to cost $12 SHIPPED which was phenomenal deal! But amazon rarely stocks the gallon jug and shipping from Nanos website is way too much now, so on to the next which is now the Megs.
