Yes, mold can grow in a cedar closet. While cedar has natural antifungal properties that resist decay and deter pests, it is not completely mold-proof. If the closet traps too much moisture, mold can easily grow on stored fabrics, dust, or other debris.
Moisture and Mildew Defense: Cedar is highly absorbent, naturally wicking away excess moisture from the air. This helps prevent the growth of mold and mildew, protecting your clothes and shoes from musty smells and dampness-related damage.
Signs of mold
Leather items can dry out and become brittle or retain an undesirable cedar scent; they should not be stored in cedar chests. Vintage clothing, uniforms, and wedding dresses can disintegrate due to the cedar's acid; ensure protection with plastic bins or acid-free tissue.
To remove mold from cedar wood, clean the surface with a gentle scrub brush and a solution of oxygen bleach or a 50/50 mix of white vinegar and water. Avoid chlorine bleach, as it can damage cedar fibers and discolor the wood. Allow the solution to sit for 15-30 minutes before rinsing thoroughly with a garden hose.
To kill mold permanently, you must combine chemical treatment with moisture control. Mold will always return if its food and water sources remain.
The truth is, it last much, much longer if you learn how to protect a cedar deck, how to care for a cedar deck, and how to clean cedar decking. Regular maintenance is key to preventing the buildup of dirt, mold, and mildew, which can lead to black spots on cedar deck wood.
Cedar blocks, balls, and hangers in a closet should be replaced or refreshed every 1–2 years. While the wood can last for decades, its scent and effectiveness against moths fade in roughly 6 to 12 months; sanding with medium-grit sandpaper or applying cedar oil can revive the scent, often extending their use to 3–7 years.
By balancing the humidity, cedar protects items from becoming musty or damp. This makes cedar closets especially useful in basements, older homes, or humid climates where moisture problems are common. Cedar closets also help neutralize odors.
Control Humidity Levels
Humidity above 50% almost always fuels mold growth in storage spaces. To keep moisture in check: Run a dehumidifier during humid seasons. Use moisture absorbers like silica gel or charcoal in closet corners.
Mold is generally at its worst from early spring through early fall (specifically July through October), peaking during the warmest and most humid months. Mold thrives in warm temperatures (60∘F to 80∘F) combined with relative humidity levels above 60%.
Early signs of mold exposure frequently mimic seasonal allergies. They include sneezing, a runny or stuffy nose, coughing, postnasal drip, and red, itchy, or watery eyes. Skin irritation or rashes may also occur, and mold can trigger or worsen asthma symptoms like wheezing and chest tightness.
Yes, mold in a closet is quite common. Because closets are typically dark, enclosed, and often lack proper ventilation, they easily trap moisture. This humidity, combined with organic materials like clothing, shoes, and wood, creates a perfect environment for mold to thrive.
A cedar closet works as a natural preservation system. It actively protects garments from pests, moisture, and odors, extending their life and maintaining their quality for years to come.
Mold releases microscopic spores into the air, and those particles circulate throughout the home, especially at night when rooms are closed and ventilation is limited. Even people who feel fine can experience irritation, disrupted sleep, or longer-term respiratory effects over time.
The primary disadvantages of cedar wood are its natural softness, which makes it prone to dents and scratches, and its high maintenance requirements to prevent fading and weathering. It is also more expensive than woods like pine and can be a respiratory irritant when cut.
To refresh a cedar closet, use fine-grit sandpaper (120 to 220-grit) to gently sand the walls in the direction of the grain. This removes the oxidized top layer and opens the wood's pores, releasing a fresh, natural aroma. Afterward, vacuum up the dust and wipe the wood down with a damp cloth.
There's a good chance you won't ever find cedar wood and bed bugs in the same place. Why? Because cedar wood contains natural oils that bed bugs and lots of other pests don't like.
Yes, cedar closets are absolutely still a thing. They are highly valued for their timeless appeal, natural moth and pest-repelling qualities, ability to absorb moisture, and the fresh, woodsy scent they provide to clothing.
Never, never finish a cedar closet with varnish, urethane or any sealer. This coating will block the cedar scent. If your old closet still does not have a strong enough cedar scent to satisfy you, you can treat the wood with natural cedar oils.
While it's commonly thought that certain woods like cedar are termite-repellent, termites can still eat them if other food sources are scarce. Regular inspection and maintenance are important to help prevent infestations, even with naturally resistant materials.
Most experts agree that adding a cedar closet adds value to any home.
Mildew: The Lesser Evil, But Still a Nuisance
It thrives in warm, moist environments but is generally easier to clean than black mold. While mildew isn't typically as dangerous as black mold, it can still trigger health problems, especially for individuals sensitive to allergens.
To remove mold from cedar wood, clean the surface with a gentle scrub brush and a solution of oxygen bleach or a 50/50 mix of white vinegar and water. Avoid chlorine bleach, as it can damage cedar fibers and discolor the wood. Allow the solution to sit for 15-30 minutes before rinsing thoroughly with a garden hose.
