Unlike standard bedding, these specialized comfort items require specific care to maintain their therapeutic benefits and structural integrity.

At Zonli, we understand that your weighted blanket is an investment in your sleep health. That's why we've created this comprehensive guide to help you properly clean and care for your weighted blanket, ensuring it remains a sustainable, long-lasting addition to your sleep routine. From understanding the unique construction of different weighted blanket types to mastering the proper washing techniques, this step-by-step guide covers everything you need to know about maintaining your comfort companion.

With the right care approach, your weighted blanket can continue providing that perfect gentle pressure and soothing comfort for years to come. Let's dive into the essential steps for keeping your weighted blanket fresh, clean, and functioning exactly as designed.

Understanding Your Weighted Blanket

Weighted blankets aren't just ordinary bedding—they're specially engineered sleep tools designed to provide therapeutic benefits through deep pressure stimulation. Before approaching the cleaning process, it's important to understand what makes your weighted blanket unique.

Most weighted blankets are constructed with an inner layer containing the weighted material (typically glass microbeads or poly pellets) distributed across pocketed sections to ensure even weight distribution. This inner layer is often surrounded by outer fabric layers that provide comfort and can be made from various materials including cotton, polyester, minky fabric, or cooling fabrics.

The filling type significantly influences how you should clean your blanket:

Glass Microbeads: These tiny, sand-like beads are the most common filling in premium weighted blankets, including many of Zonli's designs. They're environmentally friendly, hypoallergenic, and provide consistent weight distribution. They also tend to be washer-friendly when properly secured in well-constructed pockets.

Poly Pellets: Made from polypropylene plastic, these are slightly larger than glass beads and can withstand washing but may create more noise during use and cleaning.

Other Fillings: Some weighted blankets use natural materials like rice, millet, or sand, which generally cannot be machine washed as they break down with moisture exposure.

The outer fabric material is equally important to consider before washing. Natural fibers like cotton may shrink if exposed to high heat, while specialty materials like those used in cooling blankets often require gentler treatment to maintain their temperature-regulating properties.

Pre-Washing Considerations

Before you begin the washing process, take these important preliminary steps to protect your weighted blanket's integrity:

Check the manufacturer's care label: Always start by reviewing the specific care instructions provided by the manufacturer. Zonli weighted blankets come with detailed care guidelines tailored to each specific product's materials and construction.

Consider the weight: Weighted blankets typically range from 5 to 30 pounds. Blankets weighing over 15 pounds generally shouldn't go in home washing machines as they can cause damage to both the machine and the blanket. For heavier blankets, consider commercial machines or professional services.

Inspect for damage: Before washing, carefully examine your blanket for any tears, loose threads, or damaged stitching, particularly in the weighted sections. Repair any issues before washing to prevent filling from leaking and causing further damage.

Check for removable covers: Many weighted blankets, including several Zonli models, feature removable, washable covers. If your blanket has one, remove it and wash it separately according to its specific care instructions.

Washing Instructions by Blanket Type

Glass Bead-Filled Weighted Blankets

Glass bead weighted blankets, which make up many of Zonli's offerings, are generally the most washing machine-friendly, provided they're under the weight limit for your machine (typically under 15 pounds for home washers).

For machine washing these blankets:

Use cold or warm water (never hot) and set your machine to a gentle cycle. Add a mild, eco-friendly detergent without bleach or fabric softeners, as these chemicals can break down the fabric and impact the blanket's durability. Harsh chemicals also contradict the eco-friendly standards that quality weighted blankets are designed to meet.

For blankets exceeding your machine's capacity, professional cleaning services with commercial machines are recommended. Alternatively, bathtub washing (discussed later) offers a manageable home solution.

Poly Pellet Weighted Blankets

Poly pellet weighted blankets follow similar care instructions to glass bead blankets but may experience more shifting during washing. When machine washing:

Use cold water only and select the gentlest cycle available. Avoid strong agitation, which can cause the pellets to break down over time or shift more dramatically within their pockets. These blankets may require more frequent weight redistribution after washing.

Cooling Weighted Blankets

Zonli's cooling blankets feature specialized temperature-regulating fabrics that require extra care to maintain their functionality:

Always use cold water when washing cooling weighted blankets, as hot water can damage the technical fibers that provide the cooling effect. Select a gentle cycle and mild detergent. Avoid fabric softeners completely, as they leave a coating that can interfere with the cooling properties of the fabric.

For drying, air-drying is strongly recommended over machine drying to preserve the temperature-regulating qualities of the specialized fabric. If you must use a dryer, use only the lowest heat setting and remove the blanket while still slightly damp to complete air drying.

Machine Washing Guide

For machine-washable weighted blankets under 15 pounds, follow these step-by-step instructions:

Step 1: Remove any detachable covers and wash them separately.

Step 2: Treat any stains using the spot cleaning method described later in this guide before proceeding with a full wash.

Step 3: Place the weighted blanket in the washing machine, ensuring it has enough space to move. For optimal results and to protect your machine, the blanket should only fill the machine to about 2/3 capacity.

Step 4: Add a small amount of mild, eco-friendly detergent. Avoid using fabric softeners, bleach, or strong detergents with enzymes or whiteners, as these can damage the blanket's fabric and filling.

Step 5: Select a gentle or delicate cycle with cold or warm water (never hot). Hot water can damage the integrity of the blanket's materials and potentially cause shrinkage or bead damage.

Step 6: Once the cycle completes, carefully remove the blanket. Due to its weight when wet, lift from underneath with both arms rather than pulling from one edge to prevent stress on the stitching.

For balanced cleaning, it's advisable to wash your weighted blanket every 3-4 months with regular use. However, if you use it directly against your skin without a cover, or if you have allergies or pets, more frequent washing may be necessary.

Hand Washing Guide

For weighted blankets that are too heavy for your washing machine or particularly delicate, hand washing in a bathtub provides a safe alternative:

Step 1: Clean your bathtub thoroughly to remove any soap residue or cleaning chemicals.

Step 2: Fill the tub with cold or lukewarm water, enough to submerge the blanket.

Step 3: Add a small amount of mild detergent and mix it into the water until dissolved.

Step 4: Submerge the blanket fully and gently agitate the water with your hands to help the detergent penetrate the fabric. Avoid scrubbing vigorously, which can damage the internal structure.

Step 5: Allow the blanket to soak for 10-15 minutes.

Step 6: Drain the soapy water and refill the tub with clean water to rinse. You may need to repeat this rinsing process 2-3 times to remove all detergent.

Step 7: Carefully press down on the blanket to remove excess water. Do not wring or twist the blanket, which can damage the internal weight distribution and stitching.

Step 8: With assistance from another person, lift the wet blanket from the tub by supporting it from underneath to prevent stretching.

Drying Your Weighted Blanket

Properly drying your weighted blanket is crucial to prevent mold, mildew, and damage to the filling materials:

Air Drying (Preferred Method):

Lay the blanket flat on a clean, waterproof surface in a well-ventilated area. For faster drying, place it on top of a dry towel and periodically replace the towel as it absorbs moisture. Alternatively, drape the blanket over a sturdy drying rack or clothesline, ensuring the weight is evenly distributed to prevent stretching.

Flip the blanket every few hours to promote even drying. Depending on the blanket's weight and ambient conditions, air drying may take 24-48 hours. Ensure the blanket is completely dry before using or storing it.

Machine Drying (When Applicable):

If your weighted blanket's care instructions permit machine drying and it's within your dryer's capacity (typically under 15 pounds), use these guidelines:

Select the lowest heat setting possible, ideally air fluff or tumble dry low. High heat can damage the filling and fabric. Place a couple of clean, dry towels in the dryer with the blanket to help absorb moisture and reduce drying time.

Set the dryer for 20-minute intervals, checking between cycles to prevent overheating and to redistribute the filling if necessary. Remove the blanket while still slightly damp and allow it to finish air drying to prevent shrinkage and excessive wear.

Spot Cleaning Techniques

For minor stains or when full washing isn't practical, spot cleaning offers an efficient solution:

Step 1: Act quickly when spills occur—immediate attention prevents stains from setting.

Step 2: Blot (don't rub) the affected area with a clean, dry cloth to absorb excess liquid.

Step 3: Prepare a cleaning solution by mixing a small amount of mild detergent with cold water.

Step 4: Using a clean white cloth, gently dab the stain with the solution, working from the outside toward the center to prevent spreading.

Step 5: Once the stain is removed, dab with a cloth dampened with clean water to remove soap residue.

Step 6: Press a dry towel against the area to absorb moisture, then allow the spot to air dry completely.

For specific stains, adjust your approach:

For protein-based stains (food, sweat, blood): Use a solution of cold water and enzyme-based stain remover specifically designed for protein stains.

For oil-based stains: Apply a small amount of dish soap directly to the stain, let it sit for 15 minutes, then proceed with the regular spot cleaning process.

Seasonal Care and Storage

Many people switch to lighter bedding during warmer months, making proper storage of your weighted blanket essential:

Before storing, ensure your weighted blanket is completely clean and thoroughly dry to prevent mold and mildew growth. Store in a cool, dry place away from direct sunlight, which can fade colors and degrade fabrics over time.

Use a breathable storage bag—ideally cotton or canvas rather than plastic—to allow air circulation while protecting from dust. Some premium weighted blankets, like those from Zonli, come with their own storage bags specifically designed for this purpose.

Avoid compressing the blanket under heavy items during storage, as this can damage the filling and affect weight distribution. For longer-term storage, periodically air out the blanket and check for any moisture or pest issues.

When transitioning back to using your weighted blanket, give it a gentle shake and redistribute the filling by hand. If it's been stored for several months, consider a quick refresh by air fluffing in the dryer (no heat) for 10-15 minutes or airing it outside on a dry, mild day.

Troubleshooting Common Issues

Even with proper care, you may encounter these common weighted blanket issues:

Uneven Weight Distribution: After washing or extended use, the filling may shift. To redistribute the filling, lay the blanket flat and gently massage the fabric to move the beads or pellets back into position. For more stubborn cases, fold the blanket in different directions and run your hands over each section to guide the filling back into place.

Lingering Odors: If your blanket retains odors after washing, try adding 1/2 cup of baking soda to your next wash cycle, or spray lightly with a mixture of water and a few drops of essential oil before air drying. For persistent odors, place the blanket in a large plastic bag with an open box of baking soda for 24-48 hours before washing again.

Pilling Fabric: Some fabric types may develop pills with use. Remove pills with a fabric shaver designed for delicate materials, being careful not to damage the stitching. To prevent future pilling, use gentle wash settings and avoid excessive friction during use and cleaning.

Minor Tears or Loose Threads: Address small tears immediately to prevent filling leakage. For minor repairs, use a needle and thread that matches your blanket color to hand-sew the damaged area. For larger tears or damaged weight pockets, professional repair may be necessary.

Maintaining Blanket Longevity

Extend your weighted blanket's lifespan with these preventive maintenance tips:

Use a Duvet Cover: A removable, washable duvet cover acts as a protective barrier for your weighted blanket, reducing the frequency of full blanket washing. This is particularly beneficial for preserving specialized fabrics like those used in cooling blankets. Choose a cover in a breathable material that complements your blanket's therapeutic properties.

Rotate Usage: If you have multiple weighted blankets, rotating their use helps distribute wear evenly. Consider having a dedicated blanket for different seasons—perhaps a cooling weighted blanket for summer and a standard one for winter.

Keep Food and Drinks Away: Minimize exposure to potential stains by avoiding eating or drinking while under your weighted blanket.

Create a Pet Boundary: If you have pets, training them to stay off your weighted blanket reduces hair, dander, and potential claw damage. Alternatively, designate specific blankets for pet-friendly and pet-free zones.

Regular Light Cleaning: Between deep cleanings, use a handheld vacuum with an upholstery attachment on a low setting to remove surface dust and particles that can work their way into the fabric over time.

Support Your Sleep Environment: Complement your weighted blanket with quality pillows and mattress options like a futon mattress that support proper sleep posture, reducing unnecessary strain on your blanket from tossing and turning.

With proper care and maintenance, a high-quality weighted blanket like those from Zonli can provide years of comfort and therapeutic benefits. The initial investment in time for proper care pays dividends in extended product life and sustained performance.
