Help with a Keyboard Macbook Pro

[dstemacpro13]

I've had my 13 Macbook Pro for about a month and have noticed smudges on the keyboard and was wondering the best ways in removing. I've used some basic keyboard wipes from WalMart but they aren't very effective. They get the surface well but it still shows a good shadow of smudge and a reflection where the keys, almost looks like a wear. Any advice?

I use an iSkin Pro Touch and avoid all of the problems.

That's the route I plan on going once I found out how to get this out.

How's anyone used iKlear for getting the smudges out of the black keyboard keys? Any luck?
