Windex Touch-Up Cleaner

Bought this today, and I love it! The idea is fantastic! I dislike getting bottles of cleaner out just to clean up little messes... This little thing can sit on my counter, and it's just brilliant. I figure, when I run out of the cleaner that it came with, I can refill it with my choice of cleaner OR even a homemade cleaner (like Lemon essential oil).
Silly little post. But I am sold on this bottle.
