Clean and dry the nail to be treated. Apply a thin layer of Daktarin tincture to the nail and area around the nail twice daily. The nail may come off due to the infection. Before reapplying the product, clean nail of any product buildup with acetone based nail polish remover. Continue the treatment without interruption until all signs of the infection have gone and the nail appears completely normal or a new nail has formed and the lesions are completely cured (usually at least 2 months).
