|For verrucas, which are more persistent and more difficult to treat, 2 extra steps are needed prior to the treatment. First, soak the foot in warm water for 5 minutes and then rub the callous carefully with a file (widely available for purchase) to expose the persistent verruca. Dry it thoroughly so there is no water/moisture between the wart and the Wartner TCA gel. Do not apply the TCA gel when the skin is bleeding or broken. File not included.
If there is no improvement after the first treatment period of 4 days, repeat the treatment after a break of 4 days, you can repeat this treatment schedule up to 4 times. If there is no improvement after the 4 treatment, please consult a doctor.
