It is made to be used dry, or moistened with water only. I cleaned all my mirrors with it, and they look great. It was so easy, and there are no streaks. This cloth is a flat weave, I have used some with the nubs and they streaked.
Just thought I'd let you know if you're tired of streaks. I know ammonia or alcohol wiped with newspaper works well too, but I like the idea of just water. Amazingly, we have hard water and it didn't leave a film.

I believe Method also makes a similar cloth for glass.
Microfiber is the best! I use it for dusting, polishing the sink and counters and chrome in the bathroom. It's revolutionized by cleaning practices and cut WAY down on the chemicals I was bringing into the house.
Just stay away from the fabric softener or you'll ruin it.
