DampRid Fresh Scent Hanging Moisture Absorber, 3 Pack – Walmart.com.

How long does it take for DampRid to work?

DampRid crystals work immediately to absorb excess moisture from the air. The crystals harden and form a solid mass. Then they begin to dissolve and liquid will begin to drip into the bottom chamber. It may take a few days before liquid begins to drip.

What can I use instead of DampRid?

Rock salt is highly effective for dehumidifying. Rock salt or NaCl is a hygroscopic material, meaning it both draws and stores water and works much like an electric humidifier. It’s natural, non-toxic, cheap, easy to find, and easy to work with—not to mention, no electricity is needed!
