Leave the bleach on the skin over night or as long as possible.

Use a sterile cotton ball on the ringworm if you have a large patch you need to cover.


If you find the bleach mixture burns your skin, dilute it with another 1/2 cup of water. On the other hand, if you are seeing no results with the bleach treatment, bring the water amount down by 1/2 cup until you see results. Wash all bedding and clothing that has come into contact with the ringworm in very hot water.


Do not use straight bleach as it can burn and scar the skin. Once the cotton swab or cotton ball has touched the ringworm, do not return it to the bleach mixture. Be careful not to get the bleach mixture on clothing.
