I used to clean mirrors with Windex and a paper towel. Then I switched to a coffee filter, which can be dried and re-used. Now I've acquired this cleaner and a microfiber cloth. Much more green, I'd say!
Microfiber is great for picking up dust and lint--and since it's washable, it's a great replacement for paper towels.
Want to try it? Just leave a comment and I'll enter your name in the drawing for a microfiber cleaning cloth--just in time for pre-holiday cleaning! Contest open until noon 12/12 (Wed.)--anyone may enter.
