Well, it is your money, but a rapid google search would show you that a small (8 oz - 236 ml) can of Brasso can be bought for US$4.29 or a 150 ml one goes for GB£2.09
(and it can usually be fond at the grocery around the corner)
A CD polishing paste, (first one I found):
for a really tiny tube.
...and with Brasso you can also polish all your other metal or plastic hardware, or repair CD's for all your lifetime, that of your sons, of your nephews, and all other future descendants ....
