Genuine Himalayan Salt Lamps can easily absorb moisture in a humid climate. This can happen, even inside your home. Like all salt, it will take in moisture from the surrounding air and can become quite wet. As in, water litterally running off of it as if it has been placed in the shower for a few minutes. While this is normal, it can have a negative affect on your lamp and possibly even ruin it for use as the lamp can litterally disolve. It can also be a hazard. Fortunately, it is easy to avoid, and easy to fix if your lamp does get wet.
Leaving your salt lamp turned on at all times will help ensure that it does not absorb moisture. This is because the heat will keep the lamp dried out. It is also recommended for optimal negative ion output. However, if you need to turn your lamp off, or perfer not to have it on at all times, you can simply cover it with a plastic bag when it is not in use. Make sure that the bag completely covers the lamp, tucking it under the wood base to secure the bag so that moist air cannot reach it. This way your lamp cannot absorb moisture when you leave it off. When you want to use your lamp, simply uncover it, turn it on, and enjoy the enchanting glow!
In the event that your salt lamp does get wet, unplug the lamp and use a towel to pad the excess water off of the lamp. You can also use a hair dryer to dry the lamp. Either way make sure to dry it out to the point where it is safe to turn on. (No water dripping from it, not wet to the touch to the point where your finger gets wet when you touch it.) Then simply turn the lamp on and leave it on until it is completely dry. Be sure to cover your lamp the next time you turn it off, as described above, to avoid it getting wet again. If you leave your lamp uncovered and turned off in a humid climate it is best to unplug it. But as we said, it can still disolve if it gets wet, so it is best not to let this happen.
*Warning: Never operate a salt lamp that has absorbed excess moisture. Unplug the lamp immediately and allow it to dry, or dry it using the instructions above, before use.
