Insider tricks needed! Side wall clean/prep

[mockingbird812]

I scrubbed and scrubbed my side walls on my Firestone 6.70 -15 tires (brand new Coker’s) with non-diluted Simple Green- i let it dry, then followed by Westley’s Bleche-White then I used Eagle One Tire Shine (satin) to dress them. Within one day the pie crust area looked like I had done nothing to prep the tire at all! Looked terrible. I know this is bleed thru of chemicals leaching out of the tire, but what are you show-going master gurus using to curb this?

THANKS!
