You should also avoid drying the affected nail and then drying your other nails with the same towel as this may cause the fungus to spread. If you have nail fungus than an effective home remedy would be to use either antiseptic mouthwash or a formula of 50% apple cider vinegar and 50% water and to soak the affected nail in the solution a couple of times a day.
