How to Wash a Comforter

Even though your bed sheets cover your body, your comforter still picks up sweat, dead skin cells, and dust mites every night. This accumulation builds up and may lead to allergic reactions. Cleaning your comforter routinely prevents allergen buildup.

It can also help reduce odors caused by moisture buildup and prevent potential mold and mildew growth in humid environments. Over time, sweat and body oils seep through your sheets and penetrate the comforter’s filling, creating an ideal breeding ground for bacteria. 

A neglected comforter can even attract bed bugs or other pests if not cleaned regularly, making routine washing not just a hygiene step but an essential part of maintaining a healthy sleep environment.

How To Wash A Comforter?

Regular cleaning may keep your comforter fluffy too. Proper washing reduces dust mites, bacteria, and other allergens, while also maintaining fluff. Plus, washing your comforter may also extend its lifespan.

When a comforter goes unwashed, the accumulated debris causes the filling to clump together, leading to flat or uneven spots that make the bedding less cozy. Regular cleaning helps re-distribute the filling, keeps it aerated, and preserves the loft for many years.

A well-maintained comforter not only feels softer but also provides consistent insulation during cold months, ensuring a comfortable and restful sleep experience.

The best time to wash your comforter is every few months, but if you suffer from allergies, monthly cleanings are best. It’s not only important to regularly clean your comforter but to do so in the right way by following care instructions attached to your comforter.

Neglecting proper cleaning can shorten the fabric’s life, fade colors, and cause early wear and tear. Allergists often recommend frequent washes for households with pets, as pet dander tends to settle into the comforter’s layers.

Regular maintenance also keeps your bedroom smelling fresh and can prevent health issues like skin irritation or aggravated asthma symptoms.

Before Cleaning

Following these steps before washing your comforter ensures the right care. Always check the care tags, since manufacturers know how to best care for their products.

Making small repairs, like tightening loose seams and sewing up small holes, prevents worse damage. Finally, pre-treating your comforter by removing stains maintains its vibrant color and appealing look.

You should also gently shake and dust off your comforter before placing it in the washer to remove loose debris, crumbs, or pet hair. This step helps prevent your washing machine from getting clogged and ensures a deeper clean.

If your comforter has decorative embroidery, embellishments, or delicate trims, take extra precautions to avoid fraying or tearing during the wash cycle.

1. Check the Care Tags

Care tags are manufacturer instructions on how to care for the comforter. Ignoring these instructions could cause damage. You can usually find the comforter care labels by one of the bottom corners.

Most care tags state if a comforter is machine wash or dry clean only, the proper water temperature setting, type of laundry detergent, if it’s okay to use bleach, and recommended drying cycle. However, they typically do so using laundry care symbols, so it’s best to know what specifically each symbol means to prevent any improper laundering.

For example, you may not be able to clean a down comforter yourself and may have to take it to a professional cleaner. A laundry machine can reduce the comfort of a genuine down fill.

Synthetic comforters are usually easier to clean, but high-end silk, wool, or cashmere comforters often require specialized cleaning to preserve their softness and natural fibers. Some eco-friendly or organic comforters also come with strict washing guidelines to avoid chemical damage, so carefully reading the label can save you from costly mistakes.

2. Make Small Repairs

Look over your comforter and check for loose seams and holes. Make sure to repair these areas with a needle and thread before washing. It may take more time, but it’s worth it. This extra step could extend your comforter’s lifespan.

Otherwise, the washing and drying process may tear more seams or larger holes, causing the filling to leak out. If the damage is severe enough, you may have to replace your comforter.

For comforters with quilted stitching, reinforcing weak seams helps keep the fill evenly distributed after washing. If you notice missing buttons or damaged decorative elements, fixing them before the wash can prevent the issue from worsening. In case you’re not confident with sewing, consider taking the comforter to a tailor or dry cleaner for professional repair services.

3. Remove Any Stains

Before washing your comforter, remove any stains. You may not have to wash the whole comforter if it’s still clean—spot treatments work perfectly instead. But, if your comforter is due for a wash, pre-treat it by removing any stains.

Stains from body oils, makeup, food spills, or even ink can be tricky to remove once they’ve set into the fibers. Using a gentle, enzyme-based cleaner or oxygen bleach solution can effectively break down tough stains without damaging delicate materials. Allowing the stain remover to sit for at least 15–20 minutes before washing boosts its cleaning power. For particularly stubborn stains, repeating the treatment may be necessary to fully restore the comforter’s appearance.

To make a simple DIY stain remover, mix four tablespoons of baking soda and ¼ cup of cold water to make a paste. You can store the paste in an air-tight container for future use. Using warm water can set the stain and make it harder to remove.

For fresh stains, dip a soft, white rag and wet in cold water. Gently press the damp rag to the stain and lift it—scrubbing may spread the stain. Rub a small amount of DIY stain remover (enough to cover the stain) into the fabric and let it set for a few minutes. Take a clean, soft cloth and blot to remove the stain.

For older stains, dampen the area with cold water and apply enough DIY stain remover to cover the stain. Gently rub the remover into the stained area, then blot with a soft, clean cloth.

If spot cleaning only, hang the comforter in a sunny, dry area. Make sure the comforter is completely dry before using—you don’t want to risk mildew growth.

Washing Your Comforter

Before starting the washing machine, place your comforter inside to see if it will fit. Smaller sizes, like a twin, twin XL, and full, are more likely to fit. Larger comforter sizes, including a queen, king, and California king, may be more difficult.

Don’t force the comforter inside the washer. It should be loosely stuffed and evenly distributed. Running your washing machine with a tightly packed comforter may damage your machine, and the comforter may not get cleaned thoroughly. If your comforter looks like it’s tightly packed in, using a front load washing machine at your local laundromat or taking your comforter to a dry cleaner might be a better solution.

Also, consider hand washing your comforter or duvet. It will save you the hassle of taking it to the cleaners and may even save you a few bucks.

Front-load washers are preferable because they don’t have a central agitator, making them gentler on fabrics and preventing tears. When washing at home, using a commercial-size washer ensures there’s enough room for water and detergent to fully circulate, resulting in a more thorough clean.

Select the cool water temperature setting and the delicate cycle for your washing machine. If you can, add an extra rinse cycle. This will better remove dust mites, bacteria, and allergens from your comforter.

Add mild detergent for a large capacity load. This type of detergent is gentle on delicate fabrics, and if you’re washing a down comforter, it won’t strip the soft feathers of their natural oils.

Natural oils maintain insulation—using a stronger detergent may result in a flat, lumpy comforter.

Avoid using bleach or fabric softeners, as these chemicals can weaken the fibers and reduce breathability. For an extra boost of freshness, adding half a cup of white vinegar during the rinse cycle can naturally soften the fabric and help eliminate lingering odors.

If you don’t have a dryer, you may want to consider using hot water instead of cool water. Water temperature over 130 degrees kills dust mites.

Add a few clean tennis balls to the washer. Tennis balls balance the load and enable even cleaning.

Hand Washing Your Comforter

If you don’t have a washer or choose to hand wash your comforter, you can clean it using a bathtub. Follow these instructions for proper cleaning:

• Fill your bathtub with cold water and add mild detergent for a large capacity load. Swirl your hand in the water to make sure the detergent is mixed in with the water.
• Place the comforter in the bathtub until it is fully immersed in the water. Wash the comforter by gently pressing down and swirling around in the water. Never wring out the comforter—it may reduce fluff or cause damage. Let it soak for 10 minutes.
• Drain the water, gently pressing the comforter down against the bottom of the tub. Refill the bathtub with clean, cold water. Continue to press the comforter until you no longer see any suds.
• Once the comforter is sufficiently rinsed, drain the bathtub and press the comforter to remove excess water. Hang dry or place the comforter in a drying machine.

The Drying Process

After washing your comforter, place it in the dryer. You can use the same tennis balls from the washer or add wool dryer balls. Wool dryer balls speed up the drying process by absorbing moisture. Plus, they eliminate static. Both tennis balls and wool dryer balls prevent the comforter from clumping up while in the dryer.

Make sure the comforter is spread out evenly in the drum to allow balanced tumbling and airflow. If it’s bunched up or folded unevenly, the inner filling may not dry properly, leading to musty odors or mold growth. If your dryer is too small to accommodate the full size of your comforter without overcrowding, consider using a commercial-sized dryer at a laundromat. These larger machines offer better space and airflow, which helps in drying bulky bedding more effectively and evenly.

If you don’t have either tennis balls or wool dryer balls, take the comforter out of the dryer every 20 to 30 minutes and hand-fluff. Fluffing re-distributes fill and ensures even drying.

When hand-fluffing, shake and knead the comforter gently to break up any clumps forming inside the fabric shell. Pay special attention to the corners, edges, and seams—these areas tend to trap moisture and can become hard and misshapen if not fluffed regularly. Repeat this process several times during the drying cycle to maintain the comforter’s loft and softness.

Tumble dry your comforter on the low heat setting. It may take longer than the typical hour for your comforter to dry, but check it every 30 minutes until it’s done.

Avoid using high heat, as it can damage the outer fabric, melt synthetic fill, or shrink natural down feathers. High temperatures may also weaken stitching or cause the batting to clump permanently. If your comforter feels dry to the touch on the surface but still damp inside, continue drying in 10–15 minute intervals. It’s important to check the interior of the comforter by squeezing or folding it gently to feel for hidden dampness.

Once dry, take it out and air dry your comforter in a dry, sunny area for a few hours. Rotate the comforter 90 degrees every 30 minutes to prevent fill from collecting in one spot. Also, the sun’s rays kill any remaining dust mites.

Lay the comforter flat on a clean surface like a drying rack, clothesline, or large towel on a patio. If drying outdoors isn’t an option due to humidity or lack of space, hang it indoors in a well-ventilated room. Use fans or open windows to increase airflow, which helps speed up drying and ensures no moisture is trapped inside. The sunlight also acts as a natural disinfectant, helping to remove lingering odors and bacteria.

Following this process ensures the comforter is thoroughly and evenly dried. Not allowing time for the comforter to air dry may result in leftover moisture that can cause mildew to grow.

Lingering dampness not only creates an unpleasant smell but also poses health risks, especially for people with allergies or asthma. Once you’re confident the comforter is fully dry, fluff it one last time and give it a gentle shake to restore its volume. Always store the comforter in a breathable cotton bag or on an open shelf—never in a plastic bag or airtight container—as this traps moisture and encourages mold growth. Proper drying and storage extend the life of your comforter and keep it fresh for the next use.

Consider a Duvet Cover

If you want to minimize the frequency that you wash your comforter, you might want to try slipping it inside a duvet cover.

These covers add a protective barrier that keeps out allergens, limiting how often you need to wash the comforter.

You can simply toss the cover in with your sheets during the weekly wash.

Just make sure you choose a cover for the right duvet size, as a too-small cover won’t slip over your comforter or duvet insert.

FAQs

How often should you wash your bed comforter?

You should wash your comforter at least once a month. Even though your bed sheets have more direct contact with your body, your comforter still accumulates body fluids and dead skin cells. They also absorb dust mites and bacteria. Over time, your comforter may also become flat from constant use.

Regularly washing your comforter removes these allergens and leaves your comforter smelling fresh. Also, cleaning maintains the comforter’s fluffiness for continuous comfort. It’s also vital to clean your comforter before storing it away for warmer seasons. This prevents allergen buildup and ensures your comforter is clean and fresh when you bring it out of storage.

Will a king size comforter fit in a washing machine?

King size comforters can fit large capacity washing machines. However, if you have a stackable washer and dryer, your comforter may not fit. Keep in mind that a comforter of any size should be loosely packed in.

If you have to cram in your king size comforter, it might be a better option to hand wash instead. Also, most laundromats have large capacity washers and dryers. Taking your comforter to the dry cleaners is another great option.

Please don’t force your comforter into your washing machine. A tightly packed comforter won’t get cleaned and may even damage your washing unit.

Is dry cleaning better than machine washing?

Dry cleaning is often a safer option for comforters made from delicate materials like silk, wool, or down, especially if the label suggests it. It uses chemical solvents instead of water, which helps maintain the fabric’s shape and texture. 

On the other hand, machine washing works well for most everyday cotton or synthetic comforters and is more convenient and cost-effective. However, it requires a large-capacity washer and a gentle cycle to prevent clumping or tearing. The best method depends on the material, construction, and what your care label recommends.

Can I fit my king size comforter in the dryer?

We don’t recommend drying your comforter in the dryer, especially since the filling could shift in the dryer or get clumpy. Instead, air-dry your comforter on a chair in the sun or indoors with a fan on it.

Should you wash a comforter after you buy it?

Washing a brand new comforter before using it removes any remaining residues and scents attached to the fabric. It can also give you the peace of mind that your comforter is nice and clean.

A new comforter may have a lingering scent from the plastic packaging. Washing a new comforter may seem like a hassle, but it will remove any leftover allergens and leave your comforter smelling fresh.

Can I use bleach when washing my comforter?

Using bleach is generally not recommended unless your comforter is completely white and the care tag specifically says it’s safe. Even then, it’s wise to dilute the bleach and use it sparingly. Bleach can weaken the fabric over time, cause yellowing, and strip away any special coatings or treatments. If your comforter has any colored sections, patterns, or delicate stitching, avoid bleach altogether. Instead, choose a gentle, non-chlorine alternative to keep your comforter clean without damaging it.

Can you wash your comforter in hot water?

Check the care tag on your comforter for washing instructions and the correct water temperature to wash in. If your comforter is dyed with different colors, wash in cold or warm water. White comforters can usually be washed safely in hot water.

How to wash and dry a comforter without it getting lumpy?

You can use a large-capacity washer with a gentle cycle and mild detergent to wash a comforter without it getting lumpy. Also, adding dryer balls or clean tennis balls when drying may keep the filling evenly distributed. And if you have a space, then try to air-dry under sunlight as an alternative to high-heat drying, which can damage fibers. This method works for most materials washed in top loaders safely even king-size comforters. 

Will a comforter shrink in the dryer?

Yes, when dried on a high heat setting a comforter can shrink in the dryer. You must check the care label and materials, and use a low-heat or air-dry setting to avoid this issue. Materials, for example, cotton or down, are more sensitive to heat and can cause the comforter to shrink. To avoid this, tumble dry with dryer balls and make sure the comforter dries evenly. Air-drying is the safest method for heavy or king size comforters.

Conclusion

Through proper care, the best comforters can last between 15 to 20 years. Regular cleaning and fluffing, plus minor sewing repairs, may even help it last longer.

Be sure to follow the care instructions attached to your comforter. If your washer is not built for large capacity loads, a local laundromat or dry cleaner are also excellent options. Also, hand washing may take more effort on your part, but it will still result in a clean and fluffy comforter.
