Because of the high salt content, your lamp may have a tendency to "sweat", especially in humid weather. Just pat it down with a paper towel and let the warmth of the light dry up the remaining moisture. In these conditions, it's best to keep your salt rock lamp on a protected surface to protect your furniture.
