Can Urine Be Used as a Disinfectant to Kill Germs?

Perhaps you’ve noticed this when changing your cat box, but one of the main ingredients in urine is ammonia.

This means that urine can act as a disinfectant. Ammonia is also used to take out the stinging and itching of insect, jellyfish, and anemone encounters.

In our germ-conscious society, you may not be aware that cultures throughout history have in fact used urine for medicinal purposes. For some time, urine was the main ingredient in toothpaste.

The astringent properties helped kill plaque-causing bacteria in the mouth. But don’t try this at home; the stuff in modern toothpaste and Listerine works even better against our starch and sugar-rich diets..

    Urine is contrary to popular belief not sterile and therefore it should not be used as desinfectant.
