How to Freshen a Musty Guest Room Before Company
Baking Soda and Charcoal Bowls
A guest room that's been shut up smells stale and musty. Find the source first and remove it. Stir 1 cup baking soda with 1 cup activated charcoal (aquarium filter carbon from the pet aisle), divide it between 2 or 3 shallow bowls, and sprinkle 2 tablespoons dry coffee grounds on the one going where it smells worst. Set one bowl low and one up on a shelf, close the door and leave them 48 to 72 hours. Never grill briquettes.
You need
- 1 cup baking soda
- 1 cup activated charcoal, sold as aquarium filter carbon at any pet aisle
- 2 tablespoons dry coffee grounds, unbrewed
- 2 or 3 shallow open bowls or wide mouth jars
- 1 pair of old socks or a thin cloth bag, optional, for closets
Mix it
- Stir the baking soda and activated charcoal together in a bowl. The baking soda grabs acidic odors, the charcoal traps everything else in its pores.
- Divide the mix between your open bowls.
- Sprinkle the coffee grounds across the top of one bowl only. That one goes wherever the smell is strongest.
Use it
- Find the source first and remove it. A bowl of charcoal cannot beat a wet towel behind the dryer.
- Set the bowls at different heights, one on the floor and one up on a shelf. Odor molecules are not evenly distributed in a room and low bowls miss most of them.
- Leave them 48 to 72 hours with the door closed. Air movement helps, so a ceiling fan on low is a bonus.
- For a closet or a car, fill a sock with the mix, knot the end, and tuck it under a seat or on the shelf where it cannot spill.
- Stir the bowls once a week to expose fresh surface. Replace the mix every month or when it stops working.
