I'm trying to get the lightest wax possible. I put Hydrogen peroxide in the liquid wax while rendering, but have also heard that setting the wax in the sun will bleach it also. I've got a sheet of wax about 1/4 inch thick that is sitting in my back yard in any weather that happens along. How long does it take? Will dark wax be bleached white? What is the optimum thicknes?
