Cleaning Smudges From the iPad - Gadgetwise Blog - NYTimes.com
But you still may see smudges. According to the iPad user’s guide, you should not use “window cleaners, household cleaners, aerosol sprays, solvents, alcohol, ammonia or abrasives” to clean the screen. Instead, to wipe off any smudges, first, turn off the iPad — the dark screen makes smudges easier to see — and try using your luck with a microfiber cloth or even your shirtsleeve.

If you still have a smudge, add some moisture with a puff of breath, and rub a bit longer without the pressure. You can also try a slight misting with distilled water; just don’t get any liquid near the edges.

For grime on older, regular glass screens, DVDs, keyboards, mice and handheld game systems, make your own home-brew a cleaning solution for a small fraction of the price of store-bought mixtures.

Flush out the nozzle of an empty pump-spray bottle with distilled water. Fill about halfway with a 50/50 mix of pure alcohol and distilled water, both available at your local drugstores. If you have a stubborn spot, like a crayon mark, use more solution and wipe longer; don’t press. Each manufacturer has its own guidelines, so read the manual before using this on any gadget.
