## Key Points

- Always check the care label before washing: permissible modes differ even for duvets with identical filling
- The duvet must not completely fill the drum — otherwise, water and detergent will not circulate
- Temperature depends on the filling: synthetics — 30–40 °C, down — 30–40 °C on delicate cycle, wool — cold water
- Complete drying is critically important: residual moisture causes mold, odor, and filling clumps

Unlike bed linen, a winter duvet typically goes into the washing machine no more than once a year. Over time, dust, sweat, and dust mites accumulate inside the filling, causing the item to lose its freshness and original appearance. However, improper washing can cause even greater harm: the duvet filling clumps together, volume is lost, and the fabric becomes distorted. According to the British organization Which?, the main causes of these problems are overloading the drum, incorrect temperature selection, and inadequate drying. Let's look at how to avoid these mistakes and restore the duvet's softness and fluffiness.

### Step One — The Manufacturer's Label

Before loading the duvet into the washing machine, you must carefully study the care label. It indicates the permissible washing mode, maximum temperature, tumble drying options, and other restrictions. According to IKEA guidelines, acceptable modes may vary even for items with identical filling, so universal "settings" do not exist. If the label states that machine washing is prohibited, you should take the item to a dry cleaner. If washing is permitted, it is important to ensure that the duvet does not completely fill the drum: according to Which? recommendations, water and detergent must circulate freely around the item. If the duvet is too large for a home washing machine, it is better to wash it at a laundromat with large-capacity equipment.

### Temperature and Program Selection

The temperature regime depends on the type of filling, the outer fabric, and the manufacturer's instructions. The IKEA manual provides approximate values for various materials: for synthetic fillings, washing at 30–40 °C is usually acceptable; for down fillings, 30–40 °C on a delicate cycle; and for wool, cold water on a special program. It is important to emphasize that all listed temperatures are approximate, and you must check the label of the specific item before washing. According to Samsung specialists, programs such as "Bedding" or "Bulky Items" are suitable for voluminous items, provided that the washing machine supports the corresponding load and the drum is not overloaded.

### Washing Characteristics by Filling Type

Synthetic fillings are considered the easiest to care for: they handle machine washing well and dry quickly. Down duvets require a more delicate approach — according to Sleep Foundation recommendations, they should be washed at a low temperature and thoroughly dried, as moisture inside down stays trapped longer than in synthetics. Wool items suitable for machine washing, according to Woolmark recommendations, should be cleaned in cold water on a special wool program using a detergent specifically designed for wool fabrics. Using regular powder or aggressive bleach can damage the fibers and cause shrinkage.

### Drying: A Crucial Step That Cannot Be Skipped

Improper drying can ruin the results of even the most delicate wash. Down duvets approved for tumble drying should be dried at a low temperature, periodically shaking the drum to prevent the filling from clumping. If you do not have a tumble dryer, a synthetic duvet can be laid flat in a well-ventilated area — provided the label allows it — and turned over periodically while drying. Wool duvets are best dried without machine heat, ensuring uniform support for the damp fabric: hanging a heavy wet item by a single corner is prohibited, as it will deform under its own weight. A down duvet without a dryer must be dried with extreme care; if the room is cold and humid and complete drying cannot be ensured, it is wiser to use a professional laundry service with appropriate drying facilities.

### Common Mistakes and Storage Rules

One of the most common mistakes is putting the duvet into a duvet cover or storing it before it is completely dry. Residual moisture inside the filling causes a musty odor, mold growth, and the formation of clumps that cannot be straightened out by hand. Experts are unanimous: the item must be completely dry to the touch and on the inside before being folded. It is also important not to use chlorine-based bleaches for down and wool duvets, not to wring out the item after spinning, and not to dry it in direct sunlight or near an open flame. Following these simple rules will extend the service life of a winter duvet for several seasons and preserve its original volume and softness.
