I have two little boys and I am constantly pulling out my spray bottle. When I first bought this almost two years ago I got the gallon and two spray bottles and have since used them on almost everything!
I've used it to pre-treat laundry, get crayon (and many other things) off of the wall, get poop out of the carpet, pre-treat some of the worse stains in the carpet when we borrowed a carpet cleaner, mopping up after accidents when potty training and so many other things.
The best thing is that it doesn't make me sick to use, even when I was pregnant. The smell airs out much quicker when I'm done, too.
I haven't tried all the uses people come up with on the Charlie's Soap site, but it's been great for all the uses I have for it.
If you buy directly from them, their customer service was wonderful! The shipping company sent it back as damaged before it made it to me and a couple weeks later I still hadn't heard anything and wrote to them and they wrote right back and got it off to me that day.
