How To Wash King Size Comforter

Can you put a king-size comforter in the washing machine?

More specifically to successfully wash a king-sized comforter, you need a washer that has a drum capacity of 5.0 cubic feet or larger. The washer should be a front-loading washer or a top-loading washer without or with a removable center agitator.

Washing a king-size comforter in a standard home washing machine can be challenging due to its size and weight. Here are some considerations and steps to follow if you want to attempt washing a king-size comforter:

Check the Care Label: Always start by checking the care label on your comforter for specific washing instructions. Some king-size comforters may be too large or contain delicate materials that are not suitable for home washing machines.

Machine Size: The capacity of your washing machine is crucial. Front-loading washing machines with larger drums are more likely to accommodate a king-size comforter compared to top-loading machines with agitators. Ensure that there is enough space for the comforter to move freely.

Pre-Treatment: Inspect the comforter for stains and pre-treat any visible stains with a suitable stain remover according to the product’s instructions.

Use a Mild Detergent: Choose a mild detergent designed for large loads and delicate fabrics. Avoid using bleach or harsh chemicals that can damage the comforter.

Balancing Act: Distribute the weight evenly in the washing machine by placing the comforter in a balanced position. Adding a few clean tennis balls or dryer balls can help prevent uneven distribution of the filling.

Wash on Gentle Cycle: Select a gentle cycle with cold water to minimize the risk of damage. Avoid using hot water, which can cause shrinkage or damage.

Extra Rinse: Run an extra rinse cycle to ensure that all detergent residues are thoroughly removed.

Dry Properly: Tumble dry the comforter on low heat with the addition of clean tennis balls or dryer balls to help fluff and redistribute the filling as it dries. Ensure that the comforter is completely dry to prevent mold or mildew growth.

How big of a washer do I need to wash a king-size comforter?

4.5 cubic feet

Comforters: Instead of lugging your king-size comforter to a laundromat, you can wash it in any washer with a claimed capacity of at least 4.5 cubic feet, according to our tests. It’s best washed by itself, for better agitation and rinsing. An extra rinse cycle might also be helpful for these bulky items.

To wash a king-size comforter effectively, you’ll need a washing machine with a large capacity, ideally at least 4.5 cubic feet or more. King-size comforters are substantial and can take up a significant amount of space, so a larger drum size is essential to accommodate both the comforter and provide enough room for proper cleaning. Here are some guidelines:

Check Machine Capacity: Check the user manual or specifications of your washing machine to determine its drum capacity. Front-loading machines tend to have larger capacities and are often better suited for washing king-size comforters.

Measure the Comforter: Measure the dimensions of your king-size comforter. Typically, king-size comforters are around 104 inches by 88 inches, but sizes can vary. Ensure that your washing machine’s drum can comfortably fit a comforter of this size without overloading it.

Load Size: Even if your washing machine has the capacity, avoid overloading it with additional items when washing a king-size comforter. This ensures that there’s enough space for the comforter to move freely during the wash cycle.

Select the Right Cycle: Use a gentle or delicate cycle with cold water to minimize the risk of damage to the comforter’s fabric and filling.

Dry Properly: After washing, tumble dry the comforter in a large-capacity dryer on low heat. Add clean tennis balls or dryer balls to help fluff and redistribute the filling as it dries.

Are comforters too heavy for washing machine?

Unless the label specifically instructs otherwise—you can wash and dry your comforter at home using a large capacity washer and dryer with a mild laundry detergent. Simply spot clean stains and repair holes or tears, then wash using a bulky cycle with cool or warm water.

The suitability of a washing machine for washing a comforter depends on several factors, including the comforter’s size, weight, and the capacity of the washing machine. While many washing machines can handle standard-sized comforters, larger and heavier comforters, such as king-size or those with dense fillings, can pose challenges. Here’s why:

Size: Some comforters, especially king-size ones, may be too large to fit comfortably in a standard washing machine. This can lead to uneven cleaning and potential damage to the comforter.

Weight: Comforters can become quite heavy, especially when wet. Washing machines have weight limits, and attempting to wash an excessively heavy comforter could strain the machine’s motor or suspension, potentially causing damage.

Agitation: The agitator or drum in a washing machine can agitate and move a comforter around during the wash cycle. Heavier comforters may put additional stress on the machine’s components.

Balancing: Properly balancing a heavy comforter in the washing machine can be challenging. An unbalanced load can lead to excessive vibrations and possible damage to the machine.

Filling Type: Comforters with certain filling materials, like down, may require delicate care, and machine washing might not be suitable.

How often should I wash my comforter?

How often should you wash your comforter? Assuming no spills or excess dirt sully your comforter, and the comforter does not have a protective duvet, try to wash it every one to two months. If the comforter does have a duvet, you’ll be okay to clean it a few times a year.

The frequency with which you should wash your comforter depends on several factors, including personal preference, lifestyle, and the use of a duvet cover. Here are some general guidelines to help you determine how often to wash your comforter:

Personal Comfort: If you’re comfortable with it and don’t have any specific reasons to wash more frequently, you can wash your comforter every 3-6 months. This allows for seasonal cleaning and is often sufficient for maintaining freshness.

Use of a Duvet Cover: Using a duvet cover as a protective layer over your comforter can significantly extend the time between washes. Duvet covers are easier to launder and can be washed more frequently, reducing the need to clean the comforter itself.

Allergies: Individuals with allergies may need to wash their comforters more frequently, potentially every 1-2 months, to remove allergens like dust mites, pet dander, and pollen.

Spills and Stains: If your comforter experiences spills or stains, it should be cleaned promptly to prevent permanent damage. Treat stains as soon as possible, and follow care label instructions.

Pets: If you have pets that sleep on the bed, consider washing your comforter more often, as it can accumulate pet hair and odors.

Climate: In hot and humid climates, you may want to wash your comforter more often to prevent moisture buildup and maintain freshness.

How To Wash King Size Comforter

What’s the best way to pre-treat stains on a king-size comforter?

Pre-treating stains on a king-size comforter is a crucial step in ensuring effective stain removal during the washing process. Here’s the best way to pre-treat stains:

Materials Needed:

  • Mild liquid detergent
  • A soft-bristle brush or a clean cloth
  • Hydrogen peroxide (3% solution) for tough stains
  • A basin or large sink


Identify the Stain Type: Examine the stain to determine its type, whether it’s food, beverage, oil, ink, or another substance. Different stains may require specific treatments.

Blot or Scrape: If the stain is fresh, gently blot any excess liquid or carefully scrape off solids using a spoon or a dull knife. Avoid rubbing, as it can push the stain deeper into the fabric.

Create a Pretreatment Solution: In a basin or large sink, mix a solution of mild liquid detergent and cold water. Follow the manufacturer’s guidelines for the detergent’s recommended dilution.

Apply the Solution: Submerge the stained area of the comforter in the detergent solution, gently agitating it to allow the solution to penetrate the fabric. For particularly stubborn or protein-based stains like blood or sweat, you can use hydrogen peroxide (3% solution) instead of water. Pour a small amount directly onto the stain.

Soak and Agitate: Let the comforter soak for 15-30 minutes, occasionally agitating the water to encourage stain removal.

Gently Brush or Rub: Using a soft-bristle brush or a clean cloth, gently work the stained area in a circular motion to help loosen the stain.

Rinse Thoroughly: After pre-treatment, rinse the comforter thoroughly with cold water to remove the detergent or hydrogen peroxide and the loosened stain particles.

Inspect the Stain: Check the stain. If it’s still visible, repeat the pre-treatment process until the stain fades or disappears.

Can I wash a king-size comforter in a standard home washing machine?

Washing a king-size comforter in a standard home washing machine is possible but requires careful consideration and preparation due to the size and bulk of the comforter. Here’s what you need to know:

Machine Size: First, assess the capacity of your washing machine. Standard home washing machines typically have a capacity of 3.5 to 5.5 cubic feet. While some may accommodate a king-size comforter, it can be a tight fit, and the machine may struggle to effectively clean and rinse the comforter.

Comforter Type: Consider the type of king-size comforter you have. Down and synthetic-filled comforters are bulkier, so ensure that your machine can handle the size and weight. Smaller, lightweight comforters are easier to wash in a standard machine.

Preparation: Before washing, check the care label on your comforter for specific washing instructions. Some comforters may recommend professional cleaning or oversized commercial machines due to their size.

Balancing the Load: If you decide to proceed, balance the load by adding a few towels or similar items to prevent the comforter from becoming lopsided during washing, which can affect the machine’s performance.

Gentle Cycle: Select a gentle cycle with a low spin speed to minimize stress on the comforter’s fabric and stitching.

Detergent: Use a mild, liquid detergent suitable for delicate fabrics and follow the manufacturer’s guidelines for the recommended amount.

Thorough Rinsing: Ensure that the comforter is thoroughly rinsed, as detergent residue can make it stiff or uncomfortable.

Drying: Drying a king-size comforter in a standard home dryer can be challenging due to its size. Consider using a commercial dryer or a laundromat’s oversized machines for better results.

For oversized or bulky comforters, professional cleaning services or laundromats with commercial-sized machines may be a more practical choice. Always follow the care instructions provided with your comforter for the best results and to prolong its lifespan.

Should I use cold, warm, or hot water to wash a king-size comforter?

The choice of water temperature for washing a king-size comforter depends on several factors, including the fabric type and any specific care instructions provided on the comforter’s label. Here are some guidelines to help you decide:

Cold Water (30-40°F / 0-4°C):

Suitable for: Cold water is safe for most comforters and is an excellent choice for delicate or vibrant-colored fabrics that may bleed or fade in warmer water.

Benefits: Cold water is energy-efficient, helping to preserve the color and quality of your comforter. It’s also suitable for down or feather-filled comforters, as hot water can damage the filling.

Warm Water (90-100°F / 32-38°C):

Suitable for: Warm water is a versatile choice for many comforters. It effectively removes dirt and stains without the risk of color bleeding or fabric damage.

Benefits: Warm water provides a good balance between cleaning power and fabric care. It’s a safe option for most comforters.

Hot Water (130-140°F / 54-60°C):

Suitable for: Hot water is best reserved for white or heavily soiled comforters, as well as those made of sturdier materials like cotton or polyester. Be cautious with this temperature to avoid fabric damage or shrinking.

Benefits: Hot water is effective at breaking down grease and oils, making it suitable for removing tough stains and allergens.

In most cases, using warm water is a safe and effective choice for washing a king-size comforter, as it balances cleaning power with fabric care. However, when in doubt, consult the care instructions or seek professional cleaning advice.

Are there specific detergents suitable for washing king-size comforters?

Yes, there are specific detergents suitable for washing king-size comforters, and choosing the right detergent can contribute to effective cleaning while preserving the quality of your bedding. Here are some considerations:

Mild Liquid Detergent: Mild liquid detergents are a safe and commonly recommended choice for washing comforters. They are gentle on fabrics and help maintain the comforter’s softness and color. Look for detergents labeled as “gentle,” “delicate,” or “for sensitive skin.”

Hypoallergenic Detergent: If you have allergies or sensitivities, consider using a hypoallergenic detergent. These detergents are formulated to minimize allergens and irritants, making them suitable for bedding.

Down Detergent: If your comforter is filled with down or feathers, you can find detergents specifically designed for down-filled bedding. These detergents are formulated to clean and preserve the delicate down fill, often without the use of harsh chemicals.

Eco-Friendly Detergent: Environmentally friendly detergents are a great choice if you’re conscious of eco-friendliness. They are typically free of phosphates and other harmful chemicals.

Fragrance-Free Options: Detergents with added fragrances may leave a scent on your bedding. If you prefer unscented bedding, opt for fragrance-free or unscented detergents.

High-Efficiency (HE) Detergent: If you have a high-efficiency washing machine, use a detergent labeled as HE. These detergents are formulated to work effectively in machines that use less water.

Always follow the manufacturer’s recommendations on the detergent label for proper usage and dosage. Using too much detergent can lead to residue buildup on your comforter, so measure carefully.
