How to heal an infected cut
Wash your hands before and after treating the cut.
Wash up with soap and hot water for at least 20 seconds before touching your cut to avoid contaminating it further. Since it's easy to spread germs that cause infection, wash your hands again after touching the cut.
Avoid touching the cut unless you're cleaning it or changing the bandage. Scratching or playing with it can spread germs and worsen the infection.
