There's a reason you shouldn't be storing your clothes in plastic boxes according to experts

As Brits prepare for the winter by packing away their summer clothes, experts warn against using plastic storage containers. The switch to winter attire often involves storing away lighter clothing, but if you are considering plastic boxes for this purpose, you might want to rethink your choice.

Storage expert Miles Davis from Storeganise, says: "While plastic containers might seem like the best option, they’re actually full of hidden hazards for your belongings."

He revealed the downsides of using plastic for storage, explaining that such materials can trap moisture in humid spaces like attics or garages, thus becoming a perfect environment for mould to thrive.

“Plastic containers prevent airflow, so any moisture that sneaks in can’t escape. When temperatures shift, it condenses inside the box, often leaving clothes and other items a bit of a mess,” says the expert.

Hidden health risks

Davis also cautioned about health risks posed by most plastic containers due to chemicals like BPA and phthalates. These substances may seep into stored contents when heated, which is likely in places like sunny lofts or warm garages.

He suggests using BPA-free alternatives or avoiding plastic storage altogether to reduce potential health impacts.

“Beyond that, plastic boxes degrade over time, scratching, yellowing, and becoming harder to see through.

So not only do they trap moisture and harmful chemicals, but they lose their practical benefits too. With so many better options, it’s an easy switch to make,” says the expert.

Alternative steps for safer storage

Fully dry items

“Make sure clothes are thoroughly dried before storing. Damp fabrics stored in plastic can quickly become musty or mouldy over time,” says the expert.

Choose acid-free cardboard for priceless pieces

“For delicate or heirloom items, consider archive-grade acid-free cardboard boxes. These offer airflow without light exposure, preserving items without the plastic downsides,” recommends the expert.

“Museums often use them to protect historical garments, which could inspire anyone hoping to keep a wedding dress or family costume in pristine condition.”

Opt for cedar chests or closets

“Cedar wood naturally repels moths and allows airflow.

“Consider a cedar-lined closet or cedar chest for clothing items you want to keep fresh over longer periods without the mould risk,” the expert advises.

Use muslin cotton bags

Washable, breathable muslin bags offer great protection against dust and allow clothes to “breathe” in storage, unlike plastic.

For everyday items or fabrics needing gentle treatment, muslin bags are a simple, eco-friendly choice.

Try mesh bags or window screen material

Surprisingly effective for deterring pests, these bags provide ventilation and moth protection without the static of synthetics.
