Is there any cleaning solution for the MacBook Pro?
How should I clean my MacBook? Which fabric should I use to clean it?

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.

Here is a quote from the MacBook Pro: Care, Use, and Safety Information page.

Cleaning Your MacBook Pro Display.
Follow these general rules when cleaning the screen. Shut down your MacBook Pro, detach the power adapter, and remove the battery. Dampen a clean, soft, lint-free cloth or paper with water only and wipe the screen. Do not spray liquid directly on the screen.

Cleaning Your MacBook Pro
Follow these general rules when cleaning the outside of your computer and its components: Shut down your MacBook Pro, detach the power adapter, and remove the battery. Use a damp, soft, lint-free cloth to clean the computer’s exterior. Avoid getting moisture in any openings. Do not spray any type of liquid directly on the computer. Don’t use aerosol sprays, solvents, or abrasives.

I'm sure people are not using only water to clean their MacBooks and they are fine, but for me a wet microfiber cloth is sufficient.
