Should I use a sanitizer before or after I use the bathroom?

Before you go to the bathroom, it is important to wash your hands with soap and water for at least 20 seconds. You should also avoid touching surfaces that may be contaminated like door handles and light switches. After using the bathroom, you can again wash your hands with soap and water for at least 20 seconds. It's also recommended to disinfect commonly touched surfaces like doorknobs and faucets.
