I have tried about everything on my diamond back classics , over the last 10 years, and they still look like new. out in the sun they are a brilliant white. I have used simple green, Castrol super clean, purple power cleaner, Westley's bleach white ( now Black magic bleach white, comet, ajax, you name it. I have found that the westleys' bleach white, Castrol super cleaner, and simple green work the best for me. if there is a stubborn spot, I use a very fine scotch brite pad, and they clean up good. The trick is not to let a stain set on the tire for very long without cleaning it off , or it may take a set. Diamondback classic warns about this. I have also found over the years that the cooker tires that end up with yellowing often cannot be "brought back" to their original bright white , but can be improved on by using any of the above products with a scotch bright pad, or some fine sand paper. try not to use steel wool or brillo pads. the reason being, is that the metal from the steel wool, or brillo pads can become imbedded in the white wall material and eventually causing rust spots when it gets wet and not cleaned up right away. sometimes this can be worked out with one of the described cleaners and a scotch brite pad. these are just my experiences. hope they help.
