How to Sanitize and Clean Your Weighted Blanket: A Complete Guide
Weighted blankets have become essential comfort items in many homes, providing therapeutic benefits and improved sleep quality. However, like any frequently used bedding, they require proper sanitization and cleaning to maintain hygiene and longevity. Unlike standard blankets or when you wash flannel sheets, weighted blankets demand special care due to their unique construction and weight distribution materials. This comprehensive guide will walk you through the best practices for sanitizing your weighted blanket safely and effectively.
Understanding Your Weighted Blanket Before Cleaning
The first and most critical step in sanitizing your weighted blanket is to check the care label. The care label contains important guidelines specific to your blanket, such as washing temperature and whether it's safe for machine washing. Some materials, like wool or silk, may require hand washing or dry cleaning instead of standard laundering methods.
Generally, weighted blankets weighing above 20 pounds should be washed professionally at a laundromat. You should also avoid washing your weighted blanket in a washing machine if it's made from organic materials like sand, corn, beans, and rice, as these materials are non-washable. If your blanket's care label states "dry clean only," do not attempt to wash it at home—the materials are too delicate for machine or hand washing, and you should bring it to a professional cleaner to avoid damage.
Pre-Treatment: The Foundation of Sanitization
Before you begin any washing process, pre-treating stains is essential for effective sanitization. Start by gently blotting the stained area with a clean towel to absorb excess liquid before it sets into the fabric.
For visible stains, apply a solution of water and mild detergent or vinegar to the affected area, then gently dab with a soft cloth. If stains are more stubborn, use a toothbrush or soft rag to rub the stain in a circular motion for one to two minutes. For deeper cleaning, you can create a cleaning solution by mixing water with a high-quality detergent, then soak the stained area in this solution for about an hour before scrubbing.
Machine Washing Your Weighted Blanket
If your weighted blanket is machine-washable and weighs 20 pounds or less, you can clean it using a home washing machine. However, if your home washing machine isn't large enough to accommodate your blanket, visit a laundromat with commercial washers. Ensure the item has enough room to move freely during the wash to prevent uneven cleaning or damage.
Essential steps for machine washing:
- Remove any blanket cover or duvet cover before washing, as these can be cleaned separately
- Place the weighted blanket in the washer by itself—weighted blankets are already large and adding more items will overwhelm your washing machine
- Make sure the blanket is evenly distributed in the tub for balanced washing
- Select the gentle cycle using cold water, as hot water can shrink or weaken the fabric
- Use a mild, dye-free detergent with no fabric softener or bleach additives, as harsh chemicals can break down the fabric and filling over time
To remove particularly potent odors, add ¼ cup of vinegar to the washer just before the last rinse cycle, or add it after the wash cycle ends and select an extra rinse cycle on your machine.
Hand Washing for Delicate Blankets
Hand washing is an excellent option for weighted blankets that require extra care or for those who prefer a gentler approach. This method is particularly useful when you need to organize your bedroom space efficiently—similar to how you might organize hat storage or organize handbag storage, proper blanket care fits into a comprehensive home management routine.
Hand washing process:
- Fill your bathtub or a large sink with cold to lukewarm water
- Add a small portion of gentle detergent to the water and mix thoroughly
- Gently submerge the weighted blanket in water and massage the fabric for several minutes
- As the water gets dirty, drain and refill with fresh water, adding another small amount of detergent
- Repeat the washing steps until the water runs clear
- Use a soft brush to gently clean the blanket surface if needed
Drying Your Weighted Blanket Properly
Proper drying is crucial for sanitization and preventing mold and mildew growth. After washing, wring the blanket thoroughly to remove excess water—be as thorough as possible to reduce drying time.
Lay the blanket flat or hang it to air dry. If you prefer using a dryer, use low heat and add a few clean tennis balls to help distribute the filling evenly and prevent clumping. Always ensure your bedding is completely dry before using or storing it to prevent mold, mildew, or musty smells. Keep heavy bedding in breathable cotton bags in a dry area to avoid moisture buildup.
Special Situations: Sanitizing After Accidents
If your weighted blanket has been soiled by urine or other accidents, remove the blanket from the bed right away to avoid transfer of soil to other fabrics. Launder as you normally would, being careful to follow instructions on the care label. Washing in cold water with a high-quality detergent is recommended for these situations.
Common Mistakes to Avoid
Many well-meaning people inadvertently damage their weighted blankets by treating them like regular bedding. Avoid these critical mistakes:
- Using hot water: This can shrink or weaken the fabric, especially for cotton or minky covers
- Harsh detergents or fabric softeners: These break down the fabric and filling over time
- Overloading the machine: Weighted blankets can weigh between 10 to 25 pounds, which strains standard home washers and causes uneven washing
- Using bleach: Bleach damages both the fabric and the filling materials
- Improper drying: Machine drying on high heat can damage the blanket; always use low heat or air drying
Maintaining Your Weighted Blanket Between Cleanings
Regular maintenance extends the time between deep cleanings. Spot clean visible stains as soon as they appear using a damp cloth and mild soap. Ensure the beads or pellets are evenly distributed and securely enclosed before washing. After washing and drying, manually fluff your blanket to redistribute the filling and maintain its shape.
