A clean cut rarely becomes infected. Hold the cut under cool tap water or rub it clean in a basin of water.
For cuts that don't stop bleeding on their own, apply firm pressure on the wound with a sterile gauze dressing for several minutes.
Cuts should be covered with an adhesive bandage or butterfly strip.
If your cut won't stop bleeding or gapes open, if there is dirt in it that you can't remove, or if it looks infected, call your doctor.
If you haven't had a tetanus booster for 10 years, you should get a shot when injured.
