| | Crying Salt Lamp
Salt Lamps attract water. In a humid environment, they may begin to weep as excess water is absorbed. They say if you keep them lit, the heat generated by the bulb will dry them out. If the lamp is weeping even while lit, you might have it in a location that is to wet. I had one in the kitchen that started to weep because of the steam created from cooking. If you are just going to turn them off, be sure to cover them with a plastic bag to keep the moisture out.
If you can remove the electrical parts from the lamp, I have baked mine in the oven at 200 degrees to dry them out. Let it cool and put the light back in and you're good to go. Hope this helps.
