I'd recommend against using cleaners on the screen. I'd use that and a micro-fiber cloth on my iPad 1 and it ended up with all kinds of small scratches from the dust that would accumulate in the micro-fiber cloth. I don't know if the coating wore down due to the cleaners, but I suspect that is what happened. These products were labeled as "safe" for all screens, including specifically the iPad.
I'd recommend using water only, and perhaps a micro-fiber cloth, or just use paper towel with water. That's what I've done on my iPhone 4 and it stays very clean and without scratched. The coating still seems impeccable on the iPhone.
I just use a micro fiber cleaning cloth. No spray or water needed.
Using a paper towel is not a good idea. The wood pulp fibres can scratch the screen, and will damage the oleophobic coating.
I use a microfibre cloth, and when it is really dirty apply a small squirt of spectacle cleaner first.
A microfiber cloth works well for me.
Thanks for the tip regarding paper towel. As far as spectacle cleaner, don't do it. There is a reason why cameras, projectors, etc. warn against all cleaners and sprays. It damages the expensive coating on the lenses with time. This includes spetacle solutions. I don't see why the ipad coating would be any different.
I don't want to use a screen protector, but my screen already has a ton of fingerprints. For those who don't use a screen protector, what do you use to clean the screen?
