Soak the tip of the bar under hot water and gently rub the Himalayan salt cleansing bar right on the affected area. If you are washing an area with an open wound or sore, you can expect it to burn a little. This means that the salt is killing all the bacteria in the wound. Leave on for a few second and rinse. At first the cleansing bar will be a bit rough, but once the bar comes into contact with the moisture it will gradually soften up.
