Should Be Opened Once a Month: A Simple Habit That Can Prevent Big Problems
Many household problems don’t come from neglect over years—they come from small things we forget to do regularly. One surprisingly important habit that experts often recommend is opening certain things in your home at least once a month. It sounds simple, almost too simple, but this small action can prevent odors, damage, mold, mechanical failure, and even health issues.
So what exactly should be opened once a month, and why does it matter so much? Let’s break it down.
Why “Opening” Matters More Than You Think
In modern homes, many items stay closed for weeks or even months at a time. Drawers, vents, appliance doors, windows, and cabinets may seem fine left untouched—but closed spaces trap moisture, stagnant air, odors, and bacteria.
When air doesn’t circulate:
-
Moisture builds up
-
Mold and mildew can form
-
Seals can dry out or stick
-
Odors become trapped
-
Mechanical parts may seize
Opening things regularly allows airflow, movement, and early detection of problems before they become expensive repairs.
1. Windows That Are Rarely Used
Even if you rely on heating or air conditioning, windows should be opened at least once a month, even briefly.
Why it matters:
-
Prevents window frames from sticking
-
Reduces condensation buildup
-
Improves indoor air quality
-
Helps spot cracks, leaks, or damaged seals early
Homes that stay sealed for long periods often develop stale air and hidden moisture problems. Opening windows—even for 10–15 minutes—refreshes the air and protects the structure.
2. Washing Machine Door and Detergent Drawer
This is one of the most commonly overlooked areas.
Should be opened monthly (or more often):
-
Washing machine door
-
Detergent drawer
Why:
-
Prevents mold and mildew
-
Reduces unpleasant odors
-
Extends appliance lifespan
Front-loading washing machines are especially prone to mold when kept closed. Leaving the door open after use and fully opening it monthly for inspection and cleaning can prevent long-term issues.
3. Kitchen and Bathroom Cabinets
Cabinets under sinks and in bathrooms should be opened regularly—even if you don’t use them often.
Benefits:
-
Reveals hidden leaks early
-
Prevents musty smells
-
Discourages pests
-
Reduces moisture buildup
Water pipes often run through these spaces. A slow leak can go unnoticed for months if the cabinet stays closed, leading to rot or mold.
4. Refrigerator and Freezer Drawers
While the fridge is opened daily, some drawers rarely get fully emptied or opened.
Why open them monthly:
-
Prevents food residue buildup
-
Avoids hidden mold
-
Improves hygiene
-
Keeps seals flexible
Take time once a month to fully open, remove, and clean drawers. This also helps reduce food odors and cross-contamination.
5. Oven Drawer or Storage Compartment
That drawer under the oven often becomes a forgotten space.
Why it should be opened monthly:
-
Dust and crumbs can accumulate
-
Heat exposure can affect stored items
-
Pests may hide there unnoticed
Even if it’s just a storage drawer, opening and checking it regularly helps keep your kitchen safer and cleaner.
6. Spare Room Closets and Guest Room Doors
Rooms that aren’t used often can develop stale air quickly.
Opening them monthly:
-
Prevents musty smells
-
Reduces humidity buildup
-
Discourages insects
-
Protects fabrics and furniture
Closets especially benefit from airflow. Clothing stored in closed spaces for long periods can develop odors or mildew.
7. Drains and Access Panels
Some drains and access points are designed to stay closed but should still be checked.
Monthly checks help:
-
Identify slow drainage early
-
Prevent blockages
-
Reduce bad smells
-
Catch pest activity
Simply opening and inspecting—not dismantling—can alert you to problems before they worsen.
8. Rarely Used Appliances
Appliances like:
-
Guest room heaters
-
Backup fans
-
Dehumidifiers
-
Space heaters (stored, not in use)
Should be opened or uncovered monthly.
Why:
-
Prevents dust buildup
-
Ensures proper ventilation
-
Detects damage or wear
-
Reduces fire risk when later used
The Health Connection
Keeping spaces sealed for too long can impact indoor air quality. Trapped moisture and stagnant air can contribute to:
-
Mold spores
-
Allergens
-
Unpleasant odors
-
Respiratory irritation
Regularly opening things allows your home to “breathe,” creating a healthier environment.
How to Make It a Habit
A simple way to remember is to:
-
Pick one day a month (for example, the first weekend)
-
Walk through your home
-
Open, inspect, and air out key areas
It usually takes less than 15 minutes and can save you significant money and stress later.
What Happens If You Don’t?
Ignoring this small habit can lead to:
-
Mold growth
-
Stuck windows or drawers
-
Appliance odors
-
Hidden water damage
-
Shortened lifespan of household items
These issues often appear suddenly—but develop slowly over time.
Final Thoughts
The idea that certain things should be opened once a month may sound trivial, but it’s one of those small household habits that makes a big difference. From preventing mold to extending appliance life, regular opening and airing out protects both your home and your health.
