How to Clean a Weighted Blanket: Your Essential Guide
Weighted blankets are fantastic for relaxation and comfort. They provide deep pressure stimulation, helping many people feel calm and sleep better. But like any frequently used bedding, your weighted blanket eventually needs a good cleaning. Knowing how to clean weighted blanket correctly is important. Incorrect washing can damage the blanket’s internal structure or distribution of its weight.
I know you want to keep your cozy comfort item fresh and clean. This guide will walk you through everything you need to know about cleaning your weighted blanket. We will cover different types of blankets, crucial care label information, and safe washing and drying methods. By the end, you will feel confident in giving your weighted blanket the care it deserves.
Takeaway
Keeping your weighted blanket clean ensures its longevity and effectiveness. Follow these key steps:
- Always check the care label first: This is the most important step for safe cleaning.
- Spot clean minor spills: Address small stains quickly to avoid full washes.
- Use a removable cover: This protects the inner blanket and makes routine cleaning much easier.

- Air dry completely: Avoid high heat, which can damage fillers and fabrics.
To clean a weighted blanket, first check its care label for specific instructions. Most weighted blankets with removable covers allow machine washing the cover and spot cleaning the inner blanket. If the entire blanket is machine washable and your washer can handle its weight, use a gentle cycle with cold water and mild detergent, then air dry thoroughly to prevent damage.
Understanding Your Weighted Blanket: Fillers and Fabrics
Before you start cleaning, it is important to know what your weighted blanket is made of. Weighted blankets come with different types of fillers and outer fabrics. Each material reacts differently to water and cleaning agents. Understanding these materials helps you choose the right cleaning method.
Common Fillers: Glass Beads, Plastic Pellets, Grains
The weight in your blanket comes from its internal filling. Different fillers have different properties when it comes to moisture and heat.
- Glass Beads: These are tiny, smooth, and sand-like. Glass beads are very durable and generally safe for washing. They do not absorb water, making them easier to dry. Many high-quality weighted blankets use glass beads.
- Plastic Pellets: These are small, pea-sized plastic pieces. Plastic pellets can melt or deform under high heat. This is why you must avoid hot water and high heat drying when cleaning blankets with plastic fillers. They are a common and affordable filler option.
- Organic Fillers (Rice, Beans, Corn, etc.): Some DIY or older weighted blankets use natural grains or seeds. These organic fillers should never be submerged in water. They can mold, rot, or sprout if they get wet. Blankets with organic fillers are usually spot-clean only or require special dry-cleaning methods.
Knowing your blanket’s filler prevents damage during cleaning. Always prioritize protecting the internal weight distribution. This ensures your blanket remains effective and safe to use.
Popular Outer Fabrics: Cotton, Minky, Polyester, Bamboo
The outer fabric of your weighted blanket also influences the cleaning process. Different fabrics have specific washing requirements.
- Cotton: Cotton is a common and breathable fabric. It is generally easy to clean and holds up well to washing. Cotton can be machine washed but might shrink if exposed to hot water or high heat.
- Minky: Minky fabric is soft, plush, and very comfortable. It is often used for a luxurious feel. Minky fabric can usually be machine washed on a gentle cycle. However, it should be air dried or tumble dried on very low heat to maintain its softness and texture.
- Polyester: Polyester is a durable and synthetic fabric. It resists wrinkles and stretching. Many weighted blanket covers are made from polyester because it is easy to care for and durable. Polyester generally handles machine washing well. For more specific tips on cleaning this material, you can refer to how to wash a polyester blanket. how to wash a polyester blanket
- Bamboo: Bamboo fabric is known for being soft, breathable, and hypoallergenic. It is also often more delicate than cotton or polyester. Bamboo fabric usually requires gentle washing cycles and cooler water to prevent damage.
Understanding both the filler and the fabric helps you prepare for the best cleaning approach. This double-check ensures you protect your investment in comfort.
Checking the Care Label: Your First Step to Cleaning
Before you do anything else, find the care label on your weighted blanket. This small tag holds the most important information about how to clean your specific blanket. Manufacturers provide these labels to ensure you maintain the blanket properly. Ignoring the care label can lead to irreversible damage to your blanket.
The care label will show symbols that tell you how to wash, dry, and iron the blanket. These symbols are universal, so you can understand them even without words. Look for instructions on temperature settings, spin cycles, and drying methods. Some blankets may be machine washable, while others might require hand washing or even professional dry cleaning.
If your weighted blanket has a removable cover, check both the cover’s label and the inner blanket’s label. Often, the cover is machine washable, but the inner weighted portion might need a different approach, such as spot cleaning. This distinction is crucial for proper maintenance. If there is no care label, or if it is unreadable, it is safer to default to hand washing and air drying methods. This approach minimizes risk and helps preserve your blanket’s quality. Remember, a quick check of the label can save you from a ruined blanket.
Spot Cleaning: Addressing Minor Spills and Stains
Spot cleaning is your best friend for minor spills and everyday dirt on your weighted blanket. This method is often preferred because it avoids fully soaking the blanket. It also saves you the effort of a full wash, which can be challenging with heavy items. Spot cleaning is especially important if your blanket has a non-washable inner filler like grains.
You should spot clean immediately after a spill occurs. Fresh stains are much easier to remove than old, set-in ones. This quick action can prevent the stain from spreading or becoming permanent. It also keeps your blanket looking fresh between deeper cleans.
Here is a simple guide to effective spot cleaning:
- Gather Your Supplies: You will need a mild detergent, like dish soap or a gentle laundry detergent. Also, have a clean white cloth or sponge and a spray bottle filled with cool water.
- Blot, Do Not Rub: First, gently blot the stained area with a clean cloth. This lifts as much of the spill as possible without spreading it further. Rubbing can push the stain deeper into the fibers.
- Prepare Cleaning Solution: Mix a very small amount of mild detergent with cool water in your spray bottle. A little soap goes a long way here. You want a weak solution that effectively cleans without leaving residue.
- Apply and Blot: Lightly spray the cleaning solution onto the stained area. Be careful not to over-saturate the fabric. Then, gently blot the area with a clean, damp cloth. Work from the outside of the stain inward to avoid spreading.
- Rinse and Dry: Once the stain lifts, spray the area with plain cool water to rinse out any soap residue. Use a dry, clean cloth to blot up excess moisture. Allow the spot to air dry completely before using or storing the blanket. You can use a fan to speed up drying.
Spot cleaning is a convenient and effective way to manage everyday messes. It extends the time between full washes, preserving your blanket’s integrity. Always remember to be gentle and patient when treating stains.
Machine Washing Your Weighted Blanket: When Possible
Machine washing a weighted blanket is the most convenient option if your blanket and washing machine allow it. However, this is not always possible for all weighted blankets. You must consider the blanket’s weight and your washing machine’s capacity. Overloading your machine can damage both the blanket and the appliance.
Always check your blanket’s care label first. If it says “machine washable,” proceed with caution. Most standard home washing machines can handle blankets up to 12-15 pounds. Larger or heavier blankets, like those weighing 20 pounds or more, often require a commercial-sized washing machine. You can find these at laundromats.
Washing Removable Covers
Many weighted blankets come with removable covers. These covers are specifically designed for easy cleaning. This makes the cleaning process much simpler for you.
- Remove the Cover: Unzip or unbutton the cover from the inner weighted blanket. Set the inner blanket aside in a clean, dry place.
- Check the Cover’s Label: Follow the specific washing instructions for the cover fabric. Most covers are machine washable.
- Load the Machine: Place the cover into your washing machine. You can wash it with other similar items if space allows.
- Choose Settings: Select a gentle cycle with cold or cool water. Use a mild, liquid laundry detergent. Avoid bleach or harsh chemicals, as they can damage the fabric.
- Drying: Tumble dry on low heat or, ideally, air dry. Air drying helps maintain the fabric’s softness and prevents shrinkage. For polyester covers, low heat drying is usually safe. Remember, if it’s a knitted cover, laying it flat to dry helps maintain shape. For more about washing delicate items, you may find our guide on how to wash a knitted blanket useful.
Washing the Inner Blanket (if machine washable)
If your weighted blanket does not have a removable cover, or if the care label specifically states the entire blanket is machine washable, you can wash the inner blanket directly. This is typically only recommended for blankets with glass bead or plastic pellet fillings.
- Check Machine Capacity: Ensure your washing machine can handle the blanket’s weight. A top-loader with an agitator might not be suitable for very heavy blankets. A front-loading machine often works better.
- Load Carefully: Place the blanket evenly in the washing machine drum. Do not try to force it in if it is too snug. Overloading can damage your machine.
- Wash Cycle: Use a gentle or delicate cycle with cold water. Cold water protects both the fabric and the filler material. Hot water can damage plastic pellets and some fabrics.
- Detergent: Add a small amount of mild, liquid detergent. Powder detergents can sometimes leave residue, especially in cold water.
- Rinse Thoroughly: Ensure the blanket gets a complete rinse cycle to remove all soap. You might even run an extra rinse cycle to be safe. Soap residue can attract dirt and feel stiff.
- Spin Cycle: Use a normal or high spin cycle to remove as much water as possible. This step is crucial for reducing drying time and preventing mildew.
After machine washing, the inner blanket will be very heavy when wet. Handle it with care to avoid putting strain on seams. Move it directly to your chosen drying method.
Hand Washing Your Weighted Blanket: For Delicate Options
Hand washing is a gentle and safe method for cleaning weighted blankets. This method is ideal for blankets with delicate fabrics, or those too heavy for a standard washing machine. It is also the best choice for blankets with fillers that should not be machine washed, even if the label permits it, just to be extra careful. I often choose hand washing for blankets that feel too precious for a machine.
Hand washing gives you more control over the cleaning process. It reduces the stress on seams and filler distribution, which can be an issue with heavy machine cycles. While it takes more effort, it can prolong the life of your blanket. This method protects the delicate balance of weight inside the blanket.
Here is how to hand wash your weighted blanket effectively:
- Prepare Your Space: Find a large, clean space like a bathtub or a large utility sink. Ensure it is clean and free of any sharp objects or residue.
- Fill with Water: Fill the tub or sink with lukewarm or cold water. Never use hot water, especially if your blanket contains plastic pellets. Hot water can also shrink some fabrics or damage delicate ones.
- Add Mild Detergent: Pour a small amount of mild, liquid detergent into the water. Swish the water around to create some suds. Avoid using too much soap, as it will be harder to rinse out later.
- Submerge the Blanket: Carefully place your weighted blanket into the soapy water. Allow it to soak for about 15-30 minutes. Gently press down on the blanket to ensure it is fully submerged and absorbing the water. You can gently agitate it by hand.
- Gentle Agitation: Gently squeeze the blanket in sections. Avoid twisting or wringing it, which can damage the internal structure or shift the filler unevenly. Focus on gently pushing the soapy water through the fabric. If your blanket has any wool content or a similar delicate fabric, remember to handle it gently, much like you would if you were learning how to clean a wool blanket. how to clean wool blanket
- Rinse Thoroughly: Drain the soapy water from the tub. Refill the tub with clean, cool water. Gently press the blanket to release the soapy water and absorb clean water. Repeat this rinsing process several times until no more soap suds appear. This might take multiple rinses.
- Remove Excess Water: Once rinsed, gently press down on the blanket to squeeze out as much water as possible. You can roll the blanket tightly, but do not wring it. You might also lay it flat on several large, clean towels and roll them up together to absorb more water. This step is crucial because weighted blankets hold a lot of water. The blanket will be extremely heavy at this point, so be careful when lifting it.
Hand washing is a patient process. Take your time to ensure the blanket is thoroughly cleaned and rinsed. This method ensures your blanket remains in excellent condition.
Drying Your Weighted Blanket: Patience is Key
Drying a weighted blanket properly is as important as washing it correctly. Incorrect drying can lead to several problems. These include mildew growth, damaged fillers, or uneven weight distribution. Patience is key here, as weighted blankets can take a long time to dry completely.
My advice is always to prioritize air drying whenever possible. This method is the safest for all types of weighted blankets. It prevents heat damage and ensures the blanket dries evenly. High heat, especially in a dryer, can melt plastic pellets, damage delicate fabrics, and even compromise the stitching that holds the filler in place.
Here are the best ways to dry your weighted blanket:
Air Drying (Recommended):
- Lay Flat: After removing as much water as possible, lay the weighted blanket flat on a clean, dry surface. You can use a large drying rack, multiple clean towels on the floor, or even a clean tarp outdoors.
- Even Distribution: Make sure the blanket is spread out evenly. This helps the air circulate and prevents clumping of the filler.
- Rotate and Flip: Every few hours, flip the blanket over and rotate its position. This ensures both sides dry completely and helps redistribute the filler.
- Use Fans: Place a fan near the blanket to increase air circulation. This significantly speeds up the drying process.
- Sunlight (Cautiously): If drying outdoors, direct sunlight can help. However, prolonged exposure to strong sunlight can fade fabrics. Bring the blanket inside if the sun is too intense or if rain is expected.
- Drying Time: Depending on its weight and material, a weighted blanket can take anywhere from 24 to 72 hours, or even longer, to air dry completely. Do not rush this step. The blanket must be bone dry before storing or using.
Tumble Drying (Use with Extreme Caution):
- Check Label: Only tumble dry if the care label specifically permits it. Even then, use the lowest heat setting available.
- Low Heat/No Heat: Set your dryer to “air fluff” or the lowest heat setting. High heat is a major risk for melting plastic pellets and damaging fabric.
- Large Capacity: Use a large commercial dryer if your blanket is too heavy for your home machine. This prevents overloading and ensures better air circulation.
- Add Drying Aids: Place a few clean tennis balls or dryer balls in the dryer with the blanket. These help fluff the blanket and prevent the filler from clumping. They also improve air circulation.
- Check Frequently: Stop the dryer every 30-60 minutes to check the blanket’s dryness and redistribute the filler. Break up any clumps you find by hand.
- Partial Drying: Many people choose to tumble dry for a short period to remove initial moisture. Then they finish by air drying to ensure complete dryness and minimize heat exposure.
Never put a wet or even slightly damp weighted blanket back on your bed or in storage. This can lead to mildew and an unpleasant odor. Ensure your blanket is completely dry before you snuggle up with it again. This patience ensures your weighted blanket remains a clean, comfortable, and long-lasting source of relaxation.
Maintaining Your Weighted Blanket’s Freshness and Longevity
Regular maintenance is crucial for keeping your weighted blanket fresh, clean, and in good condition for years. It is not just about washing it when it gets visibly dirty. Small habits can make a big difference in its longevity. I find that a little effort daily goes a long way. This makes full washes less frequent and your blanket always ready for use.
Here are practical tips for maintaining your weighted blanket:
- Use a Removable Duvet Cover: This is by far the most effective way to protect your weighted blanket. A removable cover acts as a barrier against dirt, spills, and body oils. You can easily remove and wash the cover regularly. This significantly reduces the need to wash the heavy inner blanket. Look for covers specifically designed for weighted blankets to ensure a good fit and proper weight distribution.
- Shake and Redistribute Regularly: Weighted blankets can sometimes have their filler shift or clump over time. Gently shaking and fluffing your blanket daily or weekly helps redistribute the weight evenly. This maintains its therapeutic effectiveness and comfortable feel. Hang it over a sturdy railing or lay it flat and gently pat it.
- Aerate Your Blanket: Air your blanket out regularly. Lay it flat in a clean, well-ventilated area for a few hours. This allows air to circulate through the fabric and filler. It helps dissipate any odors and keeps the blanket smelling fresh. You can do this outdoors on a sunny, breezy day or indoors near an open window.
- Spot Clean Promptly: As discussed earlier, address spills and stains immediately. Prompt spot cleaning prevents stains from setting in and reduces the need for full washes. Always have mild detergent and clean cloths handy for quick clean-ups.
- Store Properly: When not in use for extended periods, store your weighted blanket in a cool, dry place. Use a breathable storage bag or container to protect it from dust and moisture. Avoid compressing it tightly, as this can damage the filler or fabric over time. Ensure the blanket is completely dry before storing to prevent mildew.
- Avoid Harsh Chemicals: Do not use bleach, fabric softeners, or harsh stain removers on your weighted blanket unless specifically instructed by the care label. These chemicals can damage the fabric, breakdown fillers, or leave residues that irritate the skin. Stick to mild detergents.
- Protect from Pets and Children: While weighted blankets are great for everyone, pets and young children can be tough on them. Consider using an extra throw blanket over the weighted blanket if pets are often on it. This adds another layer of protection.
- Rotate Use: If you have multiple blankets, or just want to extend the life of one, rotate its use. This prevents excessive wear and tear on one single blanket.
By implementing these simple maintenance steps, you ensure your weighted blanket remains a hygienic and comforting part of your routine. Proper care keeps your blanket feeling new.
