Quite possibly the strangest art question ever.

Just get a can of Endust Electronics spray cleaner. It's safe to use on LCDs, I've been using it for years and it's never damaged a screen. For best results use a soft paper towel, not the quilted kind.

I use the same cloth I use to clean my sunglasses.

Works for me.

You want, ideally, the kinda of soft cloth you'd use for, yup, sunglasses, glasses, or whatever. Something that soft. Even mildly abrasive cloth can scrape off the protective coating on a screen. Heck, you can scratch it off with a blunt fingernail. Most kits should come with a cloth though or the place you can get 'em should have a cloth to go with.
