How to Wash a Duvet at Home Safely (UK Guide)

Can You Wash a Duvet at Home?

Yes — in most cases. The key is knowing your filling type, checking your washing machine capacity, and following the care label. Washing your duvet at home saves money and keeps it fresh without the expense of dry cleaning.

Before You Start: Check the Care Label

Always read the care label first. Most modern duvets are machine washable, but some fillings — particularly silk and certain down-and-feather blends — require dry cleaning or specialist laundering. When in doubt, take it to a professional.

Do You Have the Right Machine?

A standard 7 kg drum can usually handle a single duvet up to 10.5 tog. A 10–12 kg machine is recommended for a king or super-king duvet, especially at higher tog ratings. If your home machine is too small, most launderettes have large-capacity commercial washers that are ideal for bulky duvets.

Washing by Filling Type

Synthetic (hollowfibre / microfibre): The easiest to wash at home. Most can be washed at 40–60°C on a gentle or delicate cycle. Spin at low speed to protect the filling.

Duck or goose down: Wash at 30–40°C on a delicate cycle with a specialist down detergent (or a small amount of mild liquid detergent). Avoid fabric softener — it coats the down and reduces loft.

Feather and down blends: Follow the same guidance as pure down. Use a gentle cycle, low temperature, and a slow spin.

Wool: Check the label carefully. Some wool duvets are machine washable on a wool cycle at 30°C; others require dry cleaning only.

Silk: Generally requires dry cleaning. Do not attempt to machine wash unless the label explicitly permits it.

The Right Detergent

Use a small amount of mild liquid detergent. Powder detergents can clump in the filling and are harder to rinse out completely. Avoid biological detergents for down and feather fills — the enzymes can degrade the natural fibres over time. Never use fabric softener.

Drying Your Duvet

Drying is the most important step. A duvet that isn't fully dry can develop mould or mildew inside the filling.

• Tumble dryer: The best option. Use a low heat setting and add two or three clean tennis balls (or dryer balls) to break up clumps and restore loft. Expect 2–3 hours for a synthetic duvet; down may take longer.
• Line drying: Possible on a warm, breezy day, but allow several hours and shake the duvet regularly to redistribute the filling. Avoid direct strong sunlight for down, which can dry out natural oils.
• Check before storing: Squeeze different sections to feel for any damp patches. When in doubt, put it back in the dryer for another 30 minutes.

How Often Should You Wash Your Duvet?

As a general guide, wash your duvet two to three times a year — or more frequently if you suffer from allergies or sweat heavily at night. A duvet cover, washed more regularly (every 1–2 weeks), is your duvet's first line of defence.
