According to Jenelle Kim, DACM, LAc, a doctor of acupuncture and Chinese medicine, you can clean your lamp with a damp cloth, and then let it air- or sun-dry. But given that authentic Himalayan salt lamps tend to sweat in humid areas, Ziskind says that it’s also important to understand that the salt sweat can stain, and recommends keeping a washcloth or a dry clean towel underneath your lamp, just in case. “Keeping the light on will help reduce sweating and keeping it out of the sun can help, too,” she explains. “Ensuring you have your Himalayan salt lamp on something will help to protect wherever it is sitting from the salt it might melt off of it.”
