Clutter isn't merely an eyesore; it can also create hidden spots where mold and dampness can thrive silently in your home during the winter months.

Accumulations of moisture-retaining materials, neglected nooks, and crowded storage spaces can lead to condensation. This not only threatens your belongings but also poses health risks.

To proactively reduce mold this winter, experts recommend decluttering these five high-risk items now to ensure your home remains fresher, safer, and healthier throughout the season.

Key Items to Declutter to Avoid Dampness

1. Outdated Paperwork and Magazines

Old paperwork, magazines, and books can easily attract mold.

Organizing your paperwork is crucial for keeping track of bills, taxes, and appointments. However, retaining physical copies can complicate matters during the cold winter months.

Petya Holevich, a cleaning expert from Fantastic Services, warns that these items can create microenvironments conducive to condensation and mold growth. Paper products absorb moisture from the air, particularly in colder months when indoor humidity may rise. Stacks of such items in basements, attics, or closets can quickly become damp, encouraging mold growth and even attracting pests.

When decluttering paper items, determine how long to keep important documents, digitize what you can using your phone or a mobile document scanner from Best Buy, and store the rest in a sealed plastic paperwork folder from Walmart to keep them safe from moisture.

If you find yourself needing to hold onto more papers than desired, there are strategies to prevent them from becoming moldy.

Punteha van Terheyden, Head of Solved, maintains stacks of magazines as part of her journalism portfolio. She mentions, 'I've preserved magazines and newspapers with my work published in them for 17 years, and none have ever developed mold thanks to three simple steps. First, I store them in temperature-controlled areas of my home. Second, they are kept in plastic lidded bins to protect them from pests and accidental spills.'

Lastly, Punteha conducts quarterly checks on her portfolio to ensure that nothing problematic has developed over the seasons. 'Digitizing them can provide an extra layer of security in case the worst happens.'

2. Houseplants Lacking Proper Drainage

Overwatered houseplant soil can quickly grow mold.

Houseplants that are overwatered or situated in very humid conditions can foster mold growth within your home. While some houseplants can deter mold, it's still wise to inspect all your pots for drainage holes and either declutter or repot those lacking adequate drainage. This not only helps prevent mold but also protects your plants from root rot.

From there, avoid overwatering or consider bottom watering your plants to prevent mold. For rooms that tend to be damp, choose plants that require less moisture, or place them on trays filled with pebbles to keep the pot above any standing water.

3. Overstuffed Closets

Avoid cramming closets to ensure proper airflow.

Decluttering your closet is crucial for more than just streamlining your morning routine. Reducing clutter allows your clothes storage solutions to breathe, which prevents condensation buildup that could lead to mold or dampness. Michael Zohouri, a mold expert and founder of Pyramid Eco, emphasizes this.

He explains, 'When spaces are packed tight, air cannot circulate properly, creating the perfect environment for condensation and mold. This is especially critical in areas adjacent to exterior walls or tucked in corners.'

Petya adds, 'Footwear, particularly leather or fabric, can retain moisture after being worn outside. Storing them in enclosed, unventilated areas like hallways or cupboards allows moisture to accumulate, which can lead to unpleasant odors and even damage nearby surfaces.'

In addition to applying effective decluttering methods to avoid overstuffing, it may also be beneficial to invest in some hanging moisture absorbers from Walmart to help manage condensation.

4. Items Stored in the Attic

Even well-insulated attics can be vulnerable to mold.

Storage in attics is particularly susceptible to dampness, especially if the area is unheated or poorly insulated. Improving ventilation by installing an attic fan from Lowe's, decluttering items, and removing items you shouldn't store in cardboard can help minimize damage risks.

Michael explains, 'People often pack these areas with clothing or old paperwork without realizing they're obstructing airflow. Dampness thrives where air is trapped. The more room you allow for air circulation, the less likely you are to encounter mold and condensation issues.'

When organizing your attic, consider using large weathertight storage bins from The Container Store to keep items protected from moisture, thus reducing the risk of damp and pest infestations.

5. Worn Towels and Sponges

Ensure linens can breathe to avoid mold and musty odors.

Similar to clothing, old towels and sponges can hold moisture, leading to mold and dampness in your home. To prevent this, Petya advises decluttering old towels and cleaning supplies that you no longer need, while storing the remainder in ventilated areas, such as the woven Sedona Honey Under Bed Storage Basket from Crate & Barrel or open top woven water hyacinth baskets from Target.

Utilizing moisture absorbers from Walmart or small desiccant packets from Amazon can also help safeguard fabric items in storage. Alternatively, for seasonal linens and towels, consider using vacuum-sealed bags from Walmart to shield against condensation and pests.
