How to get musty smell out of basement inexpensively

Place buckets of Damp Rid and run a dehumidifier

Run a dehumidifyer. We have one going all summer.

vinegar and baking soda.... or charcoal.

Odo ban is a great product for this too.

Charcoal and leave it in bowls around the space for a week or two. Also investigate why it is musty, you may need a dehumidifier.

They sell damprid in bag, charcoal, baking soda boxes and pull inns. Wash the floor real well and removed all unwanted junk and keep the windows closed because humidity gets in and adds to that dusty smell. I would check OfferUp and craigslist for a dehumidifier and check on line becausethose are on clearance right now being the summer season is coming to an end, this is worth buying if kept on 24/7.

I agree. Ditto here
