Why does my DampRid harden into a solid block?

The salt is acting like a sponge pulling the water from the air and trapping it in the upper portion of the basket. When the upper basket has completely solidified and has absorbed as much moisture as possible, it will begin releasing the water to the lower chamber of the product. back to top IT’S NOT WORKING! I have been using DampRid for years and this has never happened before. The absorption of excess moisture and the solidification of the salt crystals depend on the amount of relative humidity that is present. Mildew and mold require moisture to grow. The optimal range for growth is 70-90% relative humidity. When the relative humidity is below 62% mold does not grow. This product is chemically designed not to dry the air to a level that damages plants, animals, or clothing. Once the relative hu
