Hi Sharkir,
Memphis actualy tried that on mine too and it worked. He just poured the contents to a cloth and gently kept wiping the clear plastic. Need to have lot of patience. And left it for a while and wiped it out. I used some warm water. My issue was the same where i accidently sprayed dash board wax to it and the clear plastic became faded. It works Shakir, try it!
Good Luck,
Hola
