So, two things.
1. Why had I not heard of pinterest before??? Sooo fun!
2. I hate my tile floors. Hate. Mainly because the grout is gross and I've never found anything to clean it well. Okay, so we bought this scrubbing bubbles battery operated scrubber today at the store and it has a grout attachment, and my grout in my kitchen floor went from almost black to bright sparkly white. I have been beaming in my OCD glory and standing there staring at the floors for the past half hour. DH keeps laughing at me and telling me I'm nuts. It's wonderful!

I don't think it would work on hardwood because it is really small, handheld.

Boo!! I was picturing something like a Swiffer but actually works.
I tried it with both a natural tile and grout cleaner (not sure which brand) and an all purpose cleaner, again I'm not sure what brand, as well as with water, and even just with a little water it cleaned it sooo white!
