After you are done using the salt bar, simply place it on a glass plate and allow it to dry out of the bathroom. A good spot is in the bedroom or near the window where direct sunlight can help it dry. The next day it will be ready to use. Store it in a Ziploc bag if you do not plan on using it for a few days. Be sure to never leave the bar in the bathroom as the high humidity will cause the salt crystals to melt due to faster oxidation of the salt.
