Grease/sweat marks on my DSi? Best way to remove?

I think its mostly sweat because I don't play DS when my hands are greasy, but anyways what is the best way to remove it? I was thinking rubbing alcohol but I don't wanna take the finish off or anything...

I usually lick my shirt then wipe it. The saliva usually dries off quickly.

I use my tongue too. xD

Water usually works though.

Thanks guys. Im gonna go with water and a shirt...XD

I get that Sweat marks on my DSi I just ignore it and when I'm done playing put it in my Carrying case and then the next day all those marks are gone.
