I have an used everything from Clean and Dull, Most of the manufacturer's cleaners including the old Track Magic stuff, Storm Reacta-Shine etc. I've also used the Simple Green mixture for years having worked in several pro shops over the years too.
One thing ive noticed is the Clean and Dull does just that, it cleans and dulls, so if you are just looking to clean up the surface without removing the shine from the ball, then I'd stay away from C&D.
Most of the manufacturer's cleaners and the Simple Green mixture acheive the same result, they remove a small layer of dirt, oil and grime from the cover of the ball. Show me proof where just because the bottle has a ball manufacturer's name on it it gets better results than the Simple Green mixture...you cant.
And what's with bashing somebody because they want to do their own maintenence at home? Is it cheap, frugal?? Yeah maybe but so what? Why spend almost 3 times more for something i can mix at home and get the same results? OMG, i dont know how my Hot Rod SS pearl has lasted as long as it has, especailly since i havent used Reacta-Shine on it since i purchased it....
