Every Product, Natural or Crafted, is completely unique as they are all created by hand, and therefore vary in color, size, and shape. Lamps placed in areas with high humidity such as bathrooms and laundry rooms may absorb moisture and drip salt at the base. In such situations a plate should be placed under the lamp to protect surfaces. Crystal Salt Lamps are easy to care for. Occasionally wipe with a dry cloth. If dirt builds up, wipe with a damp cloth, this may remove a thin layer of salt.
