How to properly store polyester comforters to avoid moisture and mildew?

Cleaning and drying are the first steps before storage
Before storing a polyester comforter, make sure it is clean and completely dry. After long-term use, the surface of the quilt often adheres to human sweat, dandruff, dust or other impurities, which are easy to breed bacteria and mold in a humid environment. If the uncleaned or undried quilt is directly stored, it is likely to cause mold in a sealed storage environment.
It is recommended to use a neutral detergent to gently wash the quilt, and after washing, dry it thoroughly in a well-ventilated and sunny place until there is no moisture. In case of continuous rainy weather, a dryer or warm air equipment can be used to help speed up the drying process.

Choose suitable storage containers or tools
When storing polyester comforters, the choice of containers plays an important role in moisture-proofing. Common storage methods include plastic storage boxes, vacuum compression bags, cloth storage bags, etc.
Plastic storage boxes have good sealing properties and can effectively block moisture in the air. They are a choice with higher moisture-proof performance. Before use, check whether the box is clean and dry. Desiccant or activated carbon bag can be placed at the bottom for further dehumidification.
Vacuum compression bags are suitable for families with limited space. They reduce the volume and block the humidity in the air by vacuuming, but the vacuum seal should be tight and the bag body should not be damaged.
Cloth storage bags are highly breathable and suitable for short-term storage, but they have limited long-term moisture-proof ability. It is recommended to use them with desiccant.
Regardless of which method is used, avoid exposing the quilt directly to open space to avoid moisture and adsorption of dust and pollutants in the air.
Humidity control of the storage environment cannot be ignored. Although polyester fiber is not easy to absorb water, it will still become moldy due to adsorption of moisture in the air in a high humidity environment for a long time. Therefore, humidity control in the storage room is crucial.
It is recommended to store quilts in dry, well-ventilated areas away from bathrooms, kitchens and other humid areas. If the living environment is humid, dehumidification products such as dehumidification boxes, dehumidification bags, activated carbon or lime powder can be placed in the storage space and replaced regularly to maintain a dry state.
If conditions permit, the storage cabinet can be opened regularly for ventilation, especially during the rainy season or when the seasons change, to prevent moisture accumulation.

Avoid deformation caused by heavy pressure and improper stacking
Polyester quilts have a certain degree of resilience, but long-term heavy pressure or irregular stacking may still cause damage to the fiber structure or caking of the quilt core, thus affecting the use effect.
When storing, the quilt should be stacked as flat as possible to avoid placing heavy or sharp objects on it. If a compression bag is used, excessive vacuuming should also be avoided, leaving an appropriate margin for the filling to have room for rebound.
You can regularly turn over the storage position or rearrange the quilt to prevent permanent indentations caused by long-term fixed shape.

Regular inspection and drying to extend the service life
Even if it has been properly stored, it is still necessary to regularly check the storage status of the quilt. It is recommended to check the dryness of the quilt every one to two months, especially in seasons with high humidity, and focus on observing whether there is odor, mildew or dampness.
If you find that the quilt is slightly damp or has the beginning of odor, you can choose to take it out and dry it in the sun when the weather is clear to restore its dry state, and replace the dehumidification material in time.
This periodic ventilation and drying not only helps to inhibit the growth of mold, but also effectively delays the aging of the quilt core and the accumulation of odor, and keeps it hygienic.

Marking and partitioning storage improve management efficiency
For families with multiple quilts, it is recommended to affix identification labels when storing them, such as "Spring and Autumn Quilt", "Winter Quilt", "Children's Room Special", etc., to facilitate future use as needed. At the same time, quilts can be stored by season or room according to the frequency of use to avoid repeated opening of all storage spaces and causing moisture diffusion.
