DIY Salt Dehumidifier

Humidity can cause excess mold in basements, garages, barns and attics. It can also cause stains and fungus growth on stored items like food, clothing and antiques. Dehumidifiers pull the moisture out of the air and create a dry, cool atmosphere. Though commercial dehumidifiers can be noisy and pricey, you can create a simple dehumidifier at home with salt.

Instructions

    • 1

      Flip over your 3-gallon bucket and drill a 3-inch hole in the center with your electric hand drill. Let the drill work at its own pace; pushing will only break your bit or the drill itself.

    • 2

      Flip the bucket back over and line the inside with two layers of cheesecloth. The cloth must come up over the edges of the bucket like a trash-can liner.

    • 3

      Slip the 3-gallon bucket into your 5-gallon bucket. Tuck the edges of the cheesecloth into the 5-gallon bucket so it stays in place. The rim of the 3-gallon bucket should rest on the rim of the 5-gallon bucket.

    • 4

      Fill the 3-gallon bucket with street deicing rock salt. The salt will draw moisture into it. When the salt is soaked, the water will drip into the 5-gallon bucket. Empty the bucket every other day and replace the salt every three days or so.
