Its not that hard to get stuff looking that good, just go to your local hardware store and pick up a couple of buffing wheels.
Get the ones that are stitched very tight all the way around the wheel. In other words, a rugged one that isnt all flabby. Also pick up a flabby one to get into the hard to get crevices. ( I got mine at home depot)
Get a set of polishes that are in a wax stick form to apply to the wheels. Oddly enough, as cheap as Ryobi stuff usually is, their buffing wheel polish works Very Well. I got some from a couple other places that didnt compare, but this could have been due to the fact they were sitting on the shelf for so long.They have a bunch of differnt compounds for different materials. You only need enough so you can see it on the wheel, dont try to push hard on it to get "a lot" on the wheel, because the majority of it will go on the floor instead, so push easily until you see it build up on the wheel.
Sit down and get your stuff shiny! This will rip the oxidation off and depending on how much time you put in, will determine how good it looks.
After everything looks as good as you can get it with the Ryobi stuff. Take a towel and apply some Mothers Mag polish to the wheel (not to much cause it will fly off the wheel a little) then polish your parts quick with that and your stuff will be like a mirror.
Another tip: WEAR A MASK, the wheels will progressively desinigrate leaving behind lots of fabric dust thats sticky with polish. And you'll be breathing this crap in and coughing it up for a good while if you dont wear a mask.
This is how my stuff came out:
