Hydrogen peroxide is one of the safest sanitizers to use when you have cuts and scrapes because when it interacts with a wound, it reacts by oxidizing germs and bacteria on contact. During the process, it turns into a simple compound of oxygen and water and is completely natural. But did you know hydrogen peroxide can be used for more than just a first-aid tool? Try disinfecting cutting boards with it (with a little white vinegar) to completely sanitize it. Or spray some hydrogen peroxide on the outside of fruits and vegetables; just mist the fruit and let it sit for a few minutes, then rinse with water.
