Decolorized Iodine Tincture (D.I. TINCTURE), containing 2.86% of Iodine. 

Directions: Before the first application, cut, file and scrub the nails.  Apply liberally on and under the nails several times a day until the new and healthy nails have grown out completely. 

Faster result may be achieved by soaking the nails / toenails in Lugols Iodine solution twice a day. However, the nails and surrounding skin will be stained brown for the duration of treatment. 

For even faster results, drop a drop of Tea tree oil on the infected nails after showering.

To prevent getting infected again, ensure that the area of the shower is kept clean and dry and the nails are kept dry as well.
