DIY Dehumidifier:
Supplies
Directions
- Take one of the buckets and drill a bunch of holes in the bottom. Do 6-7 and make them ¼ inch or so across.
- Put the bucket with the holes inside the other bucket. Place about 5 pounds of rock salt in the top bucket.
- Place this in area that you want to reduce moisture in. In a few days there will be some water in the bottom. Dump this out and check it every few days. You’ll eventually need to replace the rock salt, but it is usually very cheap.
Instead of rock salt, you can also try
silica-based kitty litter or
calcium chloride. This is often sold during the winter to melt ice. Charcoal (either
briquets or
lump charcoal) will work too and remove odors at the same time. And some
zeolite rocks will pull moisture from the air. Some of the commercial dampness removing products are made from zeolites.
I hope it helps. Short of lots of fans and other more expensive ways, that's about all that's left.
