Tuff Shine Tire Cleaner, their really inexpensive, awesome brush, you may need to repeat the process, a few times to get all the brown muck out, then follow with their coating which applies white and dries clear, a couple of coats, and they will not only look great, they will really stay that way even through the constant Seattle WA., rain that falls well over 300 days a year.. Then there is the snow that comes when its not raining...
Tuff Shine makes these really nice little rectangular application sponges that are very tight so they absorb very little.. These are perfect for applying the coating, or hey - see what they do with things like Opti-Coat, etc... Yeah, you want some of these also inexpensive little gems...
I have tried many products for my Business and personal use and none of them have been able to beat these products yet...
Everything else is great but temporary, greasy, attracts dirt, etc...
Good luck !
