cleaning solutions

[dansipod40gig]

Ok so as some of you fellow forumers know im preparing to sell my 40 gig photo on ebay; what cleaning products and other such things actually remove the scratches from the front of the ipod and the metal back?
Which one is the best bang for the bucK?
I would like to make it look a few months newer as I use it everyday.
