Why is using bare unprotected hands when washing a toilet bowl with an industrial strength cleaner that contains 23 percent hydrochloric acid?

Exposure to hydrochloric acid can cause skin irritation, burns, and chemical injuries. Using bare unprotected hands when handling a cleaner with such a high concentration of hydrochloric acid puts you at risk of these harmful effects. It is important to always use appropriate protective gear, such as gloves and goggles, when working with strong chemicals like this.
