Salt naturally attracts moisture and there is moisture in the air, therefore if you leave the salt block unprotected for long period of time in a humid environment it will secrete liquid. That liquid eventually dries into white crystals. It is not recommended to leave your salt block inside the BBQ as it climate controlled. The solution is to place the salt block in a large zip-lock or any other plastic bag that can provide a secure seal from humidity. Note: place a little bit of dry uncooked rice inside the plastic bag to allow the moisture to be absorbed. It can also be used from keeping the edible salt from sticking together.
