When salt lamps are working correctly, they don’t produce any sweat. If you notice your lamp is sweating or looks oily, it may be time to change the bulb.
How do I clean my salt lamp?
Cleaning a salt lamp is easy and should only take about five minutes. Just wipe down the base of the light with a damp cloth and then dry using a soft cloth or paper towel. You can also use warm soapy water to scrub away algae that tends to form on your lighting system (it’s normal) but make sure you rinse thoroughly afterwards and allow them to air-dry before replacing in their case for storage!
