Many of these products can be found at a grocery store, which is where I get the castile soap for the cheapest price. For the other products, I prefer Sprouts. Target and Whole Foods have them too.
For household cleaning recipes, the popular supplies are castile soap, white vinegar, and baking soda. I am not quite as picky about the brands for these products. I still use Dr. Bonner's castile soap, but I usually go with the almond scented one. It mixes well with essential oils to create an amazing aroma.
