Can I wash a king size comforter in my washing machine?

Only if it fits with room to spare. A wet king size comforter is very heavy, and in a machine that is too small it can throw the drum off balance and strain the motor, bearings and suspension. Large laundromat machines are another option.

How do you dry a down comforter without clumps?

Dry it on low heat with clean dryer balls or tennis balls, and stop every so often to shake it and pull clumps apart by hand. A thick comforter often needs several cycles. Check the corners and center for dampness before using it.

How often should you wash a comforter?

A comforter used inside a duvet cover usually needs cleaning only a few times a year. One used without a cover needs it more often, since it touches skin directly. Spills, illness, pets on the bed and allergies are all reasons to clean sooner.

Cleaning comforters and bedding at home or with a professional

Comforters, duvets, quilts and blankets get used every night but cleaned far less often than sheets. They are also some of the hardest items in the house to clean well at home, because size, weight and filling all matter.

Start with the care label

The care label is the first thing to check. It tells you whether the item can be machine washed, at what temperature, whether it can be tumble dried, and whether the maker calls for dry cleaning only.

On bedding, labels are often sewn into a corner seam. Some list separate instructions for the outer shell and the fill. If the label is missing or faded, treat the item cautiously until you know what it is made of.

A few fill types call for extra care:

Down and feather fill can often be washed, but it needs thorough, gentle drying.
Wool fill can felt and shrink with heat and agitation.
Silk fill is delicate and is often labeled for dry cleaning or spot cleaning only.
Weighted blankets vary widely. Some have a removable cover and an inner blanket that are cleaned separately. Read the instructions closely, since the weight can be hard on a home machine.

When a home machine works

Many comforters and blankets can be washed at home if the machine is large enough.

Capacity is the main question. The comforter needs room to move freely in the water. If it is packed tightly into the drum, water and detergent cannot circulate through it. Parts of the comforter stay dirty, and soap stays trapped in the filling.

A simple rule: if you have to force the comforter in, the machine is too small.

Front load washers, and top load washers without a center agitator, are generally easier on bulky bedding. A center agitator can wrap and twist a comforter, tear the shell or pull stitching apart.

The large capacity machines at a laundromat are an option for bulky items that will not fit at home.

Tips for washing at home

Check for loose seams or small tears first. Washing can make them much worse and let filling escape.
Use a mild detergent, and less of it than you would for a regular load. Bulky fillings hold on to soap.
Choose the gentle or bulky cycle with the water temperature the label allows.
Run an extra rinse to clear out detergent.

When to skip the home machine

Some situations call for a different approach:

The comforter does not fit with room to spare.
The label says dry clean only.
The item is an heirloom or handmade quilt, an antique, or has fragile fabric, embroidery or appliqué.
The fabric has colors that may bleed.
The fill is silk or wool and the label does not allow washing.
Your machine has struggled or gone off balance with heavy loads before.

A king size comforter soaked with water is very heavy. In a machine that is too small, it can throw the drum off balance during the spin and put strain on the motor, bearings and suspension. That is a real risk to the washer, not just to the comforter.

Older quilts deserve particular care. Aged thread, fabric and dyes can be weaker than they look, and machine agitation can damage them in a single wash.

Drying fully to avoid mildew

Drying is where many home washes go wrong. The outside of a comforter can feel dry while the filling inside is still damp. A comforter put back on the bed or into storage while damp can grow mildew and develop a musty smell that is hard to get rid of.

Down and down alternative

Down clumps when wet. As it dries, the clumps need to be broken up so the down can regain its loft. Fiberfill and other down alternatives can also clump and shift, leaving thin areas in some places and lumps in others.

Dry on low heat. High heat can scorch the shell and damage the fill.
Add clean dryer balls or clean tennis balls to help break up clumps.
Stop the dryer every so often, take the comforter out, shake it and pull apart any clumps by hand.
Expect it to take a long time. A thick comforter often needs several cycles.
Check for dampness deep in the fill, especially at the corners and in the center.

Uneven drying is another reason capacity matters. In a dryer that is too small, the comforter cannot tumble freely, so the center stays wet while the outer edges overheat.

If you are unsure whether it is fully dry, give it more time. Extra drying on low heat is safer than storing it damp.

Air drying

Air drying a down or fiberfill comforter is slow and tends to leave the filling clumped, so a finish in the dryer on low heat is usually needed. Lighter cotton blankets and quilts can often be air dried flat or spread across several lines to share the weight. Keep them out of direct sun to limit fading.

How often to clean bedding layers

There is no single schedule, but thinking in layers helps.

Sheets and pillowcases sit against skin and pick up oils and sweat. Many people wash them every week or two.
Duvet covers can be washed about as often as sheets, since their job is to protect what is inside.
Comforters and duvet inserts used with a cover usually need cleaning only a few times a year.
Comforters used without a cover need cleaning more often, since they take direct contact with skin.
Decorative quilts and throws can be cleaned seasonally or when they look or smell like they need it.
Mattress pads and protectors should be washed on a regular schedule and right away after any spill or accident.

Spills, illness, pets on the bed and allergies are all reasons to clean sooner.

Protecting comforters with duvet covers

A duvet cover is the easiest way to extend the life of a comforter. The cover takes the body oils, sweat, makeup and spills. You wash the cover often, and the comforter itself needs cleaning far less. That means fewer trips through a washer and dryer, which is easier on the shell, the stitching and the fill.

Choose a cover close to the size of the insert so the fill does not shift and bunch inside it. Many covers have ties at the inside corners that keep the insert in place.

Storing off season bedding

When a heavy comforter goes into the closet for the summer:

Clean it first. Body oils and soil left in bedding can yellow over time, and soiled wool bedding can attract moths.
Make sure it is completely dry.
Store it in a breathable cotton storage bag, or wrap it in a clean cotton sheet. Avoid sealed plastic for long periods, since it can trap any moisture left inside.
Keep it in a cool, dry closet or under a bed. Avoid attics, garages and damp basements.
Avoid heavy compression for long stretches. Down and fiberfill may not fully regain their loft after months in a vacuum bag.
Before using it again, shake it out and let it air for a day so it can fluff back up.
