How do you safely clean an Apple keyboard? My keys have news print on them.

If your keyboard is wired, first disconnect it from your computer. If it is wireless, power off the keyboard andremove the batteries. To clean the outside of your keyboard, use a lint-free cloth lightly moistened with water. Don’t get moisture in any openings or use aerosol sprays, solvents, or abrasives.

To take ink off of the keyboard I use santi wipes from a hospital. They work wonders, and they do not effect the aluminum or lettering. If you cant get those. You my try some eyeglass cleaner sprayed onto a soft cloth. Then a little water on the soft cloth if it leaves a residue.
