Will Bleach Kill Ringworm?



Bleach WILL kill ringworm

More Info: Bleach is a reliable way to kill ringworm.  Bleach is known to kill many types of bacteria, viruses, and fungi.  Ringworm, despite its name, is not a worm, but a fungal infection that can affect the skin, scalp, feet and nails.

Making an Effective Bleach Solution

To kill a fungal infection like ringworm, dilute bleach with water at a 1:10 solution.  According to Cornell University’s Department of Veterinary Medicine, this is equivalent to 1.5 cups of bleach per gallon of water or 3 oz. of bleach per 32 oz. of water.  Using a stronger concentration could cause respiratory tract irritation.

How to Apply the Solution

Use a cotton swab to apply the bleach solution to the infected area.  Allow the bleach solution to dry.  Unless you feel discomfort, do not remove the solution.  On the next day, rinse the area with water and soap, and apply the bleach solution again.  On the third day, check to see if the ringworm is gone.

Warnings and Side Effects

When using bleach to kill ringworm, make sure to dilute it.  Using undiluted bleach can burn or scar your skin.  Try not to get the bleach solution on your clothing, as it will stain.  For sanitary purposes, once you have applied a cotton swab to the ringworm area, do not return the cotton swab to the bleach solution.
