Do NOT use winded, or any other chemical on your screen. A slightly dampened anti static microfiber cloth is all you need.
I use this method on my iMac, MBA, MBP, IPF and iPhone. You need nothing else. The only chemical substance you can use is Iclear, but it's expensive and IMO, not required.
What do you guys use to keep your screen nice and clean?
+1 I use iKlear too. It is pretty pricy, but I think it's worth it. I clean my MBA screen maybe once every like 2 months? But I also have a shaggy-mac screen protector to put inbetween my keyboard + screen when it's closed.
I have a bottle of Windex but I'm not sure if I should use it on my MBA screen. What do you guys use to keep your screen nice and clean?
