Have you ever walked into your bathroom and thought: My God! What is that smell? Mildew could be to blame for transforming your special oasis into stink central. Don't panic, we're here to help.
Mildew, or mold in its early stage, tends to be found in wet, moisture-prone areas. It looks grayish-white but can turn brown over time. According to the Federal Emergency Management Agency, mildew can grow on wood products, ceiling tiles, insulation, wallpaper, carpet, drywall, fabric, plants, and other organic materials that are commonly found in bathrooms. And once the fungus makes its way onto your precious towels and tiles, you need to get serious about eradicating it.
The first step to battling the mildew stench is to wash everything. This means washing those hand-towels that have been hanging in the bathroom forever, the musty bathroom rugs, and the stale window curtains. When laundering, experts suggest adding one cup of white vinegar to wash the load. Frequently wash your nonslip mats, too. And, toss that vinyl shower curtain and replace it with a washable cotton, hemp, or nylon shower curtain.
“Bleach can be used to clean the mildew source and stop it from growing," says Gina Perry, senior merchant of cleaning at The Home Depot in Atlanta.
For items that can withstand bleach, FEMA recommends using a 10% solution or 1.25 to 1.5 cup of bleach to a gallon of water. The bleach/water solution can also be used to wipe down shower doors, cabinets, and walls, and to mop hard floors around bathtubs and toilets.
Water can be the big culprit behind that nasty smell. “You can get a mildew smell if you have a slow drain leak under a sink or around a drain,” says Frazier. He says the same thing can happen with toilets if a wax ring seal, which seals the toilet to the flange, has a slight leak that is allowing small amounts of water to seep out under the toilet.
“The fix is to repair the leak promptly and wipe the area that got wet down with a strong, bleach-based cleaner,” Frazier says.
Bathtubs can also occasionally get a mildew smell if they're not properly sealed and if small amounts of water get between the wall and the tub. A bleaching solution can scrub away mildew on top of caulk, but if it’s underneath, it will need to be completely removed and properly recaulked.
Dark, damp, warm rooms make for a happy home for mildew to thrive. To remedy this, open the windows and let fresh air in. If you don't have a window in the bathroom, keep the bathroom door cracked open when showering. If you need more privacy and prefer to shower with the door closed (no judgment!), install a ceiling fan or consider running an electric fan to keep air moving. Open your cabinets so they can get fresh air, too.
“I find one of the biggest things homeowners can do to combat mildew smells in bathrooms is to ensure they have a properly functioning, properly sized exhaust fan,” says Frazier.
Mildew reeks, but it can also make people with allergies or asthma sick or irritate their eyes, nose, throat, and lungs.
Sara Alsén, chief purpose officer for Sweden-based Blueair, a leader in air-cleaning solutions, says placing a high-performing air purifier in the bathroom will have a twofold effect: It will remove the unhealthy mold and bacteria in the air and make the smell disappear.
“An air purifier with a high airflow will also increase the air circulation in the bathroom and as such, help fight the mold growth,” she says.
There’s nothing a new paint job can’t cure, right? Try using mold and mildew resistant paint.
Rick Watson, director of product information at Sherwin-Williams, says paints with odor-eliminating technology can help inhibit the growth of mold and mildew and reduce common indoor odors, so rooms stay fresher longer.
But make sure to treat the mildew before painting. Bathrooms are splash-prone areas, so lower parts of the walls and corners and edges near the ceiling are typical breeding areas for mildew.
After cleaning, brush a coat of mildew-resistant primer on ceiling and walls to prevent peeling in high-moisture areas. Let the coat of primer dry, then apply the first coat of mildew-resistant paint and say goodbye to that mildew smell.
Odor-absorbing items can help. Charcoal briquettes, an open box of baking soda, or a small pouch of kitty litter can make the bathroom smell fresher by absorbing the odor and the moisture in the air. However, make sure to replace them every month or so. Natural air fresheners, like essential oils or citrus peels, can also cut the stench.
