How to Treat Fungus With Listerine
Remove all nail polish and wash the affected area with soap and warm water. You must leave the nail polish-free for the duration of the treatment to encourage oxygen circulation to the nail bed.
Fill a small basin with Listerine. If you are treating fungus on the fingernails, you can use a small glass to stretch your Listerine supply.
Soak the affected nails for 30 minutes. Repeat soaking twice a day. You mustn't skip a single day, as any fungal spores that survive can continue to colonize the nail.
Double up on your treatments by applying mini-treatments of Listerine throughout the day. Keep a small container or vial of Listerine with you and apply to your nail with a clean cotton swab several times a day.
Increase the efficacy of the treatment by adding vinegar to your Listerine soak. Acidic environments are lethal to fungi, so vinegar can hasten the cure. Use a one to one ratio of Listerine to vinegar.
Continue your Listerine treatment until the affected nail has grown out completely. You must be dedicated, as this can take up to six months.
