Is there any particular cleaning solution for the MacBook Pro?
I use a dry microfiber cloth on my screen. I found them in a two-pack of washcloth-sized at Dollar General.

If you want a cleaning solution, the Apple Store folks, at least in Madison WI, fully endorse iKlean and use it on their display models every night. I can't vouch because I haven't used it, but I figure Apple knows Apple well.
