You've surely used hydrogen peroxide to clean out a cut before applying a bandage, but did you know it's also great for household cleaning? This natural product is a great stain remover for carpets and clothes and in conjunction with vinegar, it's an excellent scum buster for your tub and tile. And unlike vinegar, it doesn't have a noticeable smell nor does it need to be diluted with water. If you get a sprayer the same size as the cap, you can just use it right of the bottle. It's also handy for washing your produce and cleaning your teeth. Also note, if you go the sprayer route, it needs to be dark and opaque. Light will destroy any disinfecting qualities hydrogen peroxide has.
