How to wash a duvet

A duvet is an essential part of our bedding. We keep it on the bed for several months, sometimes all year round, and it naturally accumulates dust, perspiration, and dust mites. However, we don't always think about cleaning it regularly. How do you wash a duvet correctly, without damaging or deforming it? Should you opt for a washing machine or dry cleaning? How often should you clean it?

Here's a simple and clear guide to answer all these questions.

Unlike sheets, which are in direct contact with the skin, duvets may seem to stay "clean" longer. However, they also deserve regular, thorough care.

- Every 6 months: for daily use
- Every 3 months: if you sweat a lot at night or let a pet sleep on the bed
- At least once a year: for duvets used occasionally (vacation home, guest room)

Between full cleanings, regularly airing out the duvet by the window helps to limit bad odors and humidity.

Yes, washing a comforter in a machine is entirely possible, provided you follow a few rules.

First and foremost, check the care label: it specifies the material, the grammage, the maximum temperature, and specific instructions:

The drum volume is essential for the duvet to move freely and wash properly

For a duvet size of

• 140 x 200 cm, the minimum machine capacity must be 7 to 9kg.
• 200 x 200 cm, the minimum machine capacity must be 10 to 12kg.
• 240 x 220 and 260 x 240 cm, the minimum machine capacity must be 12kg or dry cleaning recommended.
  
  

If your machine is too small, it's best not to force it: the duvet might come out poorly rinsed or misshapen.

• Synthetic fiber duvets: 40°C is sufficient
• Cotton duvets: 40°C to 60°C depending on the label
• Down or feather duvets: 30°C on a delicate cycle

Excessive heat can damage the filling, cause clumping, or flatten the loft.

• Delicate or bulky laundry cycle
• Gentle spin (800 revolutions maximum)
• A long rinse is recommended to thoroughly remove detergent

Tip: add two clean tennis balls to the drum to prevent the filling from clumping during a duvet wash.

Machine washing requires special attention:

• Use liquid detergent (it dissolves better)
• Avoid fabric softener, which can coat the fibers and reduce breathability
• Make sure the duvet is perfectly dry before putting it back on the bed, otherwise there's a risk of mold

To wash a down comforter, choose:

• A special down or delicate cycle
• A low temperature (30°C)

Drying is crucial for the down to regain its loft:

• Tumble dry on low heat
• Add 3 to 4 tennis balls
• Remove the comforter every 30 minutes to shake it and redistribute the filling

This type of filling can take several hours to dry properly.

Washing a duvet by hand can be useful if:

• The material is delicate
• The machine is not large enough

Place the duvet in a bathtub filled with lukewarm water and mild detergent:

1. Let soak for 1 to 2 hours
2. Gently press (do not wring)
3. Rinse several times until the water runs clear
4. Let drain then dry flat or tumble dry on low heat

This method for washing a duvet is long, but effective in preserving the fibers.

Dry cleaning for duvets is recommended if:

• The duvet is very bulky
• The filling is high-quality down
• There are difficult stains to remove
• You are unsure of the appropriate program

Dry cleaners use professional machines that guarantee thorough cleaning and optimal drying.

Even if well-maintained, a comforter doesn't last forever.

Signs it's time to change it:

• It has lost its loft
• The filling is clumping
• It no longer keeps you warm enough
• It has a persistent odor

Generally, the average lifespan of a comforter is 5 to 10 years, depending on its use and quality.
