Katherine, I'm with you on the natural cleaners. I use this to clean walls and floors:
1 gallon water, 2 tablespoons white vinegar, 2 tablespoons liquid soap, (for floors I add 10 drops essential oil)
I use Dr. Bronner's Peppermint Soap, because I like the way it smells, and I usually use Tea Tree oil because it is a natural antibacterial. I don't put the essential oil in for washing walls because I don't want it to hurt the paint.
Hope this helps!
