I like making my own cleaners when I can — they're simple, they smell good, and I know exactly what's in them. The cleaning power mostly comes from the soap, vinegar, and baking soda, the oils are mainly for scent, so you get a clean house without a house full of strong chemical smells. Safety notes: use only a few drops of oil per bottle, don't use these as a disinfectant if someone's sick, skip vinegar on marble, granite, or other natural stone, and be careful around pets — tea tree and some other oils aren't safe for cats and dogs, so check before you spray around them.
