Go to discount, or advance, or autozone and pick up a $.99 sample of Meguire's Plast-X. Should last forever.
Best I've ever used, just only use it in cool shade and you have to use alot of elbow grease.
If it doesn't work, then you're only out $.99. Then you can buy a $30 bottle of cleaner you will only use once.
But, It will work, trust me on this one.
