Keeping your home fresh isn’t just about quick cleaning—it’s often the unnoticed habits that allow odors to build up. Beyond obvious sources like trash, hidden routines can create odor hotspots. Here are ten common habits that might be causing smells, plus tips to keep your space consistently fresh.

Ignoring Your Washing Machine

Your washing machine might be a hidden source of smells if not cleaned regularly. Over time, detergent, fabric softener, and grime build up in the drum and seals, creating a musty odor. Experts recommend running an empty cycle with vinegar or a store-bought washing machine cleaner every month.

Skipping the Fridge Clean-Out

While most people clean out expired food, very few people pay attention to regular fridge maintenance. Spills and crumbs that accumulate on shelves and drawers can develop mold or create bad odors over time. Wiping down the inside of the fridge every couple of weeks helps keep smells at bay.

Overlooking the Garbage Disposal

If your kitchen still smells even after taking out the trash, your garbage disposal could be the culprit. Food particles can get stuck and rot, creating a foul smell. Run cold water and add ice cubes, a bit of baking soda, or even citrus peels to freshen it up. Doing this weekly can help keep odors out of your sink.

Leaving Damp Towels Around

Damp towels or clothes left on bathroom or bedroom floors can quickly become a breeding ground for mold and mildew. These can release an unpleasant, musty odor if not dried properly. Always hang towels to dry fully before putting them in the laundry basket, and wash them weekly to prevent smells from building up.

Not Cleaning Pet Accessories

Pets bring plenty of joy but can also add to household odors, especially when their beds, collars, and toys aren’t cleaned regularly. Pet beds accumulate hair, dirt, and oils, leading to persistent smells. Washing these items on a regular schedule, at least once a month, can help minimize pet-related odors in your home.

Keeping Indoor Plants Overwatered

Houseplants purify the air but can become smelly if overwatered. Overwatering can ultimately lead to root rot, which not only harms the plant but also produces a foul smell. Ensure pots have adequate drainage and allow the soil to dry out between waterings. Consider adding charcoal to the soil, which can help absorb excess moisture and odors.

Forgetting to Change the HVAC Filter

A clogged HVAC filter can reduce airflow and allow dust, dirt, and allergens to circulate, leading to stale or musty air. Experts recommend changing filters every 1-3 months to keep the system working efficiently and improve air quality. A clean filter keeps your home smelling fresh and reduces allergens, making it a win-win.

Leaving Dirty Dishes Overnight

Leaving dishes overnight might not seem like a big deal, but it can quickly turn into a bad-smelling habit. Food residue starts to break down and produce odors. After using dishes, rinse them and put them in the dishwasher or wash them right away to prevent odors.

Not Taking Out Recycling Regularly

Even if recycling items are clean, they can still develop an odor over time, especially if items aren’t thoroughly rinsed. This is particularly true for containers that hold milk, juice, or sauce. Try to rinse each item before placing it directly in the bin, and empty your recycling regularly to keep your home smelling fresh.

Neglecting Upholstery Cleaning

Sofas, cushions, and curtains often absorb smells from pets and food. Over time, these soft surfaces can develop a musty or stale smell. Vacuuming upholstery, washing cushion covers, and using fabric refresher sprays can help maintain a fresh scent. For deeper cleaning, consider steam cleaning or professional services.
