Why is using water to wash a wound insufficient to prevent wound infection?

Water only removes physical debris lodged in the flesh. An antiseptic such as a  BETADINE® Wound Care product (our BETADINE® Antiseptic Ointment and BETADINE® First Aid Cream) is used to kill surface germs and prevent infection.20

Additionally, the use of tap water to cleanse the wound would not be recommended in a country where a constant supply of potable drinking water is not available.
