I love the idea of switching over to natural cleaning techniques. It's hard to think about making your own cleaners when you work full time and are going in a gazillion different directions when you aren't working. While I'm not 100% converted to using only natural cleaning products yet, I have found white vinegar to be so helpful and easy (and cheap!).
It's this easy! I went to the dollar store and bought a couple spray bottles. Then, I filled them with 2 parts vinegar and 1 part water and labeled them with a piece of tape. I keep one bottle downstairs and one bottle upstairs. At first the smell reminded me or dying easter eggs, but now that I use it more often, it just makes me think of "clean"!
There are tons of sources on the web and in books at your local library to find ways to use vinegar and other natural cleaning products. I recently stumbled upon this site for uses for vinegar specifically. http://www.vinegartips.com/Scripts/
Hopefully this helps you start and continue your path toward safe cleaning in your home!
