I've been using the new Meguiar's All Purpose Cleaner diluted 10:1 with water. Works really well. You either have to find it at a paint supplier or on the internet though. For something off the shelf, O'Reillys, Autozone, and Wal-Mart carry a product that works good. Can't remember the name but it is in a purple can. Tuf Stuf also works good.
