Q: I bought a used couch. Once I got it inside, I noticed it has a musty basement smell. I sprayed it with Febreeze, and that helped some, but the smell is still there. What else can I do??
Tip #1: The absolutely best way would be to allow the couch to sit outdoors in the direct sun (preferably during the summer, as the sun isn't as strong in the winter months). Other things you might try would be to sprinkle it with lots of baking soda and let it sit for awhile, then vacuum. This might help, but probably won't be 100%.
Tip #2:: Mix 1 cup vinegar, 1 cup ammonia, 1 gallon of water. Wash couch down or spray well.
Tip #3: Clean the couch with a steam cleaner using a pet odor or odor removing
detergent. Also if the cushion covers zip off you can put them in the washer or take them to the dry cleaners. You could even replace the foam cushions. Larger fabric stores carry the 4-6 inch thick foam.
Tip #4: I have used my ozone/ion air purifier by Eco Quest to remove
a musty smell from an old unfinished basement and from clothing
that sat for years in a drawer. I also used it to remove strong cat
odor from my car seats. You can find a dealer online. These are
awesome machines. I took rancid oil smells out of the wooden
kitchen cabinet where I store plastic containers. That smell had
been there for years and now it's gone and hasn't returned for
over 3 years.
