Best way to clean my iMac screen?

Just the front. The 'Glass' bit... (It IS glass isn't it?)

I've been sat close to it for a week now, and I guess I've coughed a couple of times, and Im just seeing little marks here and there.

Assuming it is glass, just a glass cleaning spray? Or do I need to get an expensive kit with special fluid and special type of cloth?

I don't mind getting a proper kit, if its worth it. I can afford to, but if theres no real need I wont... Whats the best way?

I did google, and got all these youtube vids telling me how to remove the front panel with suction grips to get at the actual screen inside... But I'm NOT at that point... I Just wanna wipe down the front 'glass' panel.

And well I'm asking, what is the little tiny black cloth, with an apple logo on it, that came with imac for? The keyboard I presume? It seems WAY to small for the screen?

Thanks!

a glass cleaning rag (found in expensive sunglasses or probably the black coth material you already have) and diluted windex will do the trick.

I personally use iKlear.

I also use iKlear but that is left over from my LCD days. With the glass fronts that most of the Macs have - pretty much any glass cleaner will do.

The black cloth is a no lint cloth so you can use it for cleaning the screen. You don't need a large cloth to clean it. If it isn't too dirty any no-lint cloth should wipe it off just fine.

Dampen a paper towel with water and use that.

Damp microfiber towel.
