Go to home depot and check out the Oxy Clean and Citrus Clean products that they carry. Secret is in getting a plastic brush (some thing like a scalp cleaning brush people use in the shower) and working it up to a good foam after you spray it. Fell a sleep one night drinking chocolate milk. Don't ask. Jumped to my feet and the milk went every place. Took me an hour to clean and the wife still doesn't know about it. Good stuff. That has been over a year ago.
