I've used two screen cleaning sprays: WOOSH AN MISTIFY. And both work well.
I spray the into a microfiber towel that comes with the bottle. I want the cloth damp and not wet.
These sprays also works on pen tablets, but the effects aren't especially dramatic.
Here's a good video showing WOOSH in use: https://www.youtube.com/watch?v=6zNUKkehnpc
