Was it shiny at some point or was it always a flat finish? It depends upon whether the diamond plate was/is polished or plated. Either way you can start with a good aluminum polish and a polishing wheel on a drill (or by hand). There are many products to polish aluminum but the easiest to find is made by Mothers - usually available at most any auto parts store, Wal-mart, etc.

Thanks for the response. Can't answer to have been shining or not, though I would guess not. Purchased used in November. It does appear heavily oxidized (at least that is how I would describe it) and were I have attempted some serious hand polishing to test, it does appear bright just can't say if it was ever really the bright polished or not. I am also looking to clean up some of the pitting that seems to have occurred.

Were it mine, I would first use Aluminum Jelly, Aluminum Polish, Aluminum Brightener, Aluminum Cleaner from Loctite Adhesives
Then proceed to polishing with standard buffing compounds designed for aluminum truck fuel tanks and wheels. If you prefer to make you own polishing compounds look here: Substitue For Elbow Grease? - Escapees Discussion Forum post #2.

On any oxidiized aluminum the first thing I do before polishing is use some vinyl siding cleaner avaialble at Ace Hardware. This will open the pores and also clean the aluminum making it easier to polish. Eliminate this step if it is already polished and just needs a touch up.

Diamond plate is one of the hardest things to polish.

There are plenty of good aluminum polishes available at all of the truck stops.

Regular flour also removes the black residue left after polishing.
