Welcome aboard. Do you have a soft or hard cover? I have the soft cover. Most of the time I just wash it, but when it gets bad, I use a convertible top spray. It gets off any nastiness that the sponge and soap won't.
Kinda depends on the type of cover you have, really. I have the Undercover Classic which is pretty much just reinforced plastic. I use meguiars Vinyl/rubber/plastic protector. Keeps the cover shiny and protected from UV fading/cracking. Car duster now and again keeps the pollen off of it to keep it lookin clean!
