Another option is to clean out infected tissue and remove the damaged nail. The applicator's wide-tip tip applies the appointment to larger areas of the feet such as the soles or in-between toes. For about 20 minutes, soak the affected foot in a bowl that contains one part vinegar and two parts warm water. If it isn't treated, the fungus can spread to other feet and harden the nails. This means that you have a large potential audience to promote it to.
