When you have a minor cut or scrape, how do you clean it out? While soap and water can take care of cleaning most cuts and scrapes, an antiseptic may help reduce the risk of infection. There are many kinds on the market, some with mild anesthetics to reduce the pain. However, two common standbys are hydrogen peroxide and isopropyl alcohol, also known as rubbing alcohol, which kill bacteria on contact.
And having a bottle of isopropyl alcohol around comes in handy for other uses, too -- it'll clean your bathroom fixtures, tweezers and thermometers, remove hairspray from the bathroom mirror and even prevent ring around the collar.
