I used listerine when both my big toenails became infected, thick, yellow, crusty, and painful. the listerine did the trick. 15 minute soak in pure mouth wash for a few nights. pain went away, and the infection stopped spreading. my doctor confirmed that the toenails were no longer infected. I just had to wait for the yellow toenails to grow out.
CAUTION. DON'T USE GREEN/BLUE varieties. My green feet were much harder to explain than my yellow toenails (but at least that faded after a week). Smells great, feels tingly fresh, and worked. :)
