what can I use to clean my screen?

I use - and have used for decades - the iKlear cleaning solutions (sometimes can be found in Apple Stores - I usually buy my refills from iKlear or Amazon).

Great products - "made" for Apple products. Get the starter kit which will have everything that you need for only $25 (less from Amazon).

Good luck,

Clinton

I used to use the same product as clintonfrombirmingham and is has a good proven track record. However recently I have switched to 'Windex electronics' cleaner. I use a small microfiber cloth to apply the solution and a very large one to wipe it off. It seems to do as good a job if not a better one at about one tenth the cost! The windex container is about 10 time size if the miniature iKlear bottle. Ideal for miserly cheapskates like me.

Ciao.
