best way to clean keyboard?

I have the thin aluminum imac keyboard. looks dirty. how do I clean it? in all the tight spaces between the keys?

Qtip and water seems to work well for between the keys. any other ideas?

Compressed air is a good tool to have, just blast all the junk out of it.

Take it apart if you have to (or if you can for that matter).

Cleaning Your Keyboard
Follow these guidelines when cleaning the outside of your keyboard:
Remove the batteries from the keyboard.
Use a damp, soft, lint-free cloth to clean the exterior of the keyboard. Avoid getting moisture in any openings.
Don’t use aerosol sprays, solvents, or abrasives.

But if that doesn't work, it's suggested to take it into an authorized service provider. Hope that helps some.
