32. 32

    Myth: Boiling water can disinfect it completely. Fact: Boiling water can kill most bacteria and viruses, but it may not remove chemical contaminants.

33. 33

    Myth: All disinfectants are safe for use on skin. Fact: Many disinfectants are too harsh for skin and should only be used on surfaces.

34. 34

    Myth: More disinfectant means better cleaning. Fact: Using too much disinfectant can be harmful and is often unnecessary. Follow the recommended amounts for effective disinfection.

35. 35

    Myth: Disinfectants work instantly. Fact: Most disinfectants need to remain on surfaces for a certain period to be effective. Check the label for the required contact time.

Fun Facts About Disinfection

Disinfection might seem like a serious topic, but it has some interesting and fun aspects too.
