Ciclopirox
"Have had toenail fungus on 4 toes of one foot.  Big and little toes for 50 years.  Other 2 for 10 years.  Tried all sorts of creams.  Also spread to my heal.  I dealt with my heal first.  Continued emery board use after showers and got rid of that.  Used ciclopirox on the toes for 2 years.  Applied once per day.  It is sticky.  I let it dry a little and then put my white sock on.  The cotton of the sock stuck to the polish a little per day.  In 2 weeks a mat forms that can be pulled off after a shower to start over again.  No need to try to remove the polish with solvent every week.  3 nails are now fungus free.  The big toe is 70% free.  I've started again on the big toe. "
