A musty smell might be described as earthy, moldy, stale, or dank. Of course not everyone has the same smell descriptors (and not everything can be described as dank), but I think we can all agree that for the most part, a musty smell is not a good thing. If you’ve ever been an old house, it may smell a bit like this. It is an indicator of decay, a sign of uncleanliness, and it could also be unhealthy. My house seems to be perennially musty as the spring thaw tends to bring some moisture into my basement. I have to work to keep that moisture from taking over. The thing I worry about is that I know some people that live in musty smelling houses who are just used to it. Odor conditioning is our mind’s way to deal with strong odors that won’t go away. It might be a blessing in some situations, but with musty scents it seems to be just sad and dangerous to your health. And since we care about our readers, look on to find the best ways to protect your health.
Best Musty Smell Removal Methods
First identify the source. A musty smell tends to mean that you have mold growing somewhere. Mold likes a specific environment: damp, dark, and warm. It can grow in places outside of those parameters, but it thrives, growing quickly in places like a sheet-rock wall which has a leaky pipe dripping onto it. It doesn’t even have to be a leaky pipe, it could just be a cold water pipe in a humid environment causing condensation. One would think that if the leak were obvious you would have noticed it before it gets musty. Check places you don’t normally go, like behind walls, in crawl spaces, and in your attic. It doesn’t take much of a musty smell to make things unpleasant.
Remove wet material and damaged materials. There are certain materials which you just aren’t going to be able to repair or clean once they have been damaged by moisture and mold. Sheetrock tends to expand making it unsightly and a haven for dangerous mold. Fiberboard and chip boards can get warped and begin to decompose. Carpet and the cushioning or liner underneath can get sodden with moisture and become dank smelling pretty quickly. There isn’t a good way to clean and dry carpet that has become musty. Sometimes it’s better to remove everything and start over. Remember to wear protective breathing equipment to avoid the spores and dust. Vacuum when you are done.
Clean the area of all mold spores. Once you’ve removed material damaged by the mold you will be left with bare studs, concrete foundation, or something hard that fended off the moisture. It’s time to do some cleaning. Cleaning the area will get rid of staining left by the mold, kill any spores still left, and help to reduce musty smells that might still be lingering around the area. While wearing protective gloves and a mask, scrub the area clean with a brush. A good homemade mold remover recipe is: one part boric acid, two parts white vinegar, two parts hydrogen peroxide, and four parts water. Try not to use too much of the cleaner as it will contribute to excess moisture in the area.
Now deodorize and ventilate the area. Once the area has been scrubbed and excess moisture mopped up, it’s time to really dry it out by adding an airflow. You could set up a box fan or a space heater. Maybe you could plan this around a nice breezy day and open up the windows? Fresh air is going to make things dry faster and smell better. If the odor still persists, you could try scrubbing the area with a baking soda/water paste or try just sprinkling a large amount in an area for a few hours and then vacuum it up later. Whatever you do, don’t repair a damaged wall without letting it dry out first.
Be sure to get rid of the source of the dampness. Having now removed all of the damaged materials and spent a couple of hours scrubbing and drying the area of mustiness, you are now as aware as anyone of how important being proactive in your home repairs can be. The earlier you catch that leak, the sooner you seal that bathtub liner, the faster you insulate that cold water line, the less hassle you’ll have in the long run. It’s all about maintenance. Keep that dehumidifier running, keep those drains from clogging, check you gutters for clogs and direct them away from your foundation. These and a hundred other daily proactive efforts will add up to a much easier time of it for you as a homeowner.
Musty Smell in Clothes
If your clothes are starting to get a musty smell, it could just be that they have absorbed the smell of wherever you are storing them. Check your closet or dresser for signs of mold growth. If your closet just has a funky odor, consider putting an open box of baking soda inside to absorb and neutralize that musty smell. It could also be that you are putting your clothes away before they are completely dry, and some mildew is forming on the damp clothes. It could also be that your washing machine has a musty smell and it is transferring to your clothes. Try flushing out your washer by running it extra full of extra hot water with extra bleach. Also adding some baking soda to your everyday wash can help neutralize odors in the machine. For that, you may need a bit of baking soda, so we’d recommend the 4lb box of Arm & Hammer from Amazon.
Control Musty Smell in Basement
Temperature control. Our first parameter is controlling the heat in your basement. Mold thrives in warmer temperatures, especially if it is wet. If you can keep it cooler, the musty smell won’t be as likely to grow. This isn’t going to work if you have someone living in your basement, which means you’ll just have to keep it drier.
Humidity control. Another parameter to control is our moisture level. As we have discussed, mold requires a certain level of moisture to be viable. It seems like even if there isn’t any mold, there is still a musty smell if things get humid. It is as if the wetness reactivates the smell. Getting rid of humidity is easy with the use of an air conditioner or a dehumidifier. Something like the Eva-dry at Amazon may work, but you’ll want to probably get something a bit larger if you’re going whole-home instead of closet or bathroom.
Ventilation control. The third parameter to controlling mustiness in your basement is airflow. Proper ventilation and air movement will do a lot to control the first two parameters. One element of mustiness is the stale quality of the air when it hasn’t been moving around much. Vent to the outside if you can, but even just having an oscillating fan blowing can do wonders.
Mold Related Health Risks
There are thousands of different molds out there and I bet they all have a smell which could be described as musty. Some molds are fairly harmless, some can cause allergic reactions or respiratory distress, and some can actually make you so ill you could die. It’s the black mold Stachybotrys chartarum you always hear about in reference to houses and sick building syndrome. Discovery of a black mold problem in your house can lower property value dramatically. Mold remediation, which is hiring someone to remove the mold and clean the area safely, might be your best bet. That black mold can lead to mycotoxicity, sinus infections, asthma attacks, pneumonia, and death. Not something you want to mess around with.
