Wombat~Here is a web site for it to get more info.
http://www.drbronner.com/ I got mine from my local co-op that is in my neighborhood. You can find it at any natural foods place like Whole Foods or some people talk about Wild Oats, but that's not around here, and not sure it's in MD. That may be a west coast chain. I've seen Trader Joe's mentioned too. Not sure if that's in your area either.
How I used it was straight outta the bottle onto the floor! I used one of those bristle floor brushes and squirted a little on the floor added some water and scrubbed up! Then I'd rinse with a mop and hot water.

There is different scents too. I also have Sals Suds which is pine. There is lavender, which I want. Others that I can't think of at the moment.
Good luck finding it!
