Millions of people use public restrooms daily, whether at work, restaurants, or transit stations, but these places may harbor various types of germs that can threaten health.

However, knowing how to handle them significantly reduces the risk of infection.

An adult produces more than one liter of urine and over 100 grams of feces daily, which carry bacteria and viruses into restrooms. People with diarrhea excrete larger amounts of these germs, making restrooms a fertile environment for germ accumulation if not cleaned regularly, especially in crowded places.

Studies indicate that door handles, faucet handles, and water flow activation elements often contain more germs than toilet seats, due to frequent use and inadequate handwashing.
