Your electric blanket or heated mattress pad is washable, so long as you know these general tips to get it safely clean.

How Often to Wash Electric Blankets
Electric blankets or throws and heated mattress pads can make your bed cozy on cold nights and provide relief to sore muscles and aching joints. As with any blanket, frequent use means your electric blanket will get dirty from body oils and maybe food or beverage spills, too. Blankets and throws also collect dust mites and pet dander.
So, you should wash your electric blanket at least two or three times during the cold season while it’s in use, and again before storing it for the warmer months. (See also, How Often to Clean Everything.)
Steps to Wash Your Electric Blanket
Before you start washing your electric blanket, make sure your home machines are large enough for the task. Your blanket needs enough space in the washer to swirl, and enough room to tumble dry. If it’s crowded in the washer, follow the tips further down to hand-wash it in the bathtub. If it’s crowded in your dryer, the commercial dryers at your local laundromat offer more space.
Active time 45 minutes.
Materials and Supplies
• Mild laundry detergent
• Microfiber cloth
• Washing machine
• Clothes dryer (optional)
• Clothesline or drying rack
- Unplug and shake it
Remove the power cord and controller from your blanket. Then, shake the blanket to dislodge as much dust and pet hair as possible. Since you’ll be using a very short wash cycle, this step helps get your electric blanket cleaner quickly.
- Pre-treat stains
Remove food spills and other crusty messes from your blanket’s surface with a rubber spatula or old credit card. Pre-treat stains by dabbing them with a small amount of laundry detergent or even soap and warm water on a microfiber cloth. Avoid rubbing stains, since this can spread the mess.
- Set the washing cycle and temperatures
Top Loading Machines: Use half the usual amount of laundry detergent, and no other laundry additives. Set the washer for the gentle cycle using cold water. Let the machine’s drum fill with water, so the detergent dissolves. Then add your blanket to the washer’s tub, arranging it around the agitator. If needed, you can add a lint-free towel or sheet to the load to balance it.
Front Loading Machines: Set the washer on the delicate cycle using a cold water setting. Add a minimal amount of detergent and the blanket. Do not use bleach, fabric softener, or any other laundry additives. - Time the washing cycle
Start the washer and let it agitate for 2 to 3 minutes, then skip to the rinse cycle. Allow the machine to complete the rinse and spin, then remove the blanket immediately after the spin cycle ends.
- Dry your electric blanket
Use a low heat setting for 15-20 minutes, just long enough to remove excess water. Then transfer your electric blanket to a clothesline or drying rack to finish air-drying away from direct sunlight, which can damage the heating elements.
- Plug it in
Feel the blanket in several places with your hands to ensure it’s completely dry before you return it to your bed and plug it back in.
Washing Older Electric Blankets
All electric blankets manufactured in the U.S. since 1990 are required by law to be washable. If your blanket is from overseas, or you are not sure where it was made, consult the care label’s washing instructions. Or, if it came with a user manual, follow the manufacturer’s instructions for washing and drying.
Hand-Washing Electric Blankets
Fill your bathtub with 3-4 inches of cool water and swirl in 2 tablespoons of mild laundry detergent until dissolved. Add your electric blanket and soak it for 10 minutes, agitating it a few times with your hands. Take care that you do not bend the wires. Drain the tub and gently press down to remove soapy water. Refill the tub with fresh water to rinse away the soap and immediately drain it again. Carefully roll your blanket to get rid of excess water without bending the wires, then follow the steps to dry it in the dryer or air-dry it over a rack.
Important Tips
• Do not use bleach. Chlorine bleach can damage the electrical components in your heated blanket.
• Avoid soaking. It’s important to minimize how long your electric blanket or heated mattress pad remains wet. Be sure to watch the times carefully for the best results.
• Do not use high heat. If you choose to use your dryer, make sure to tumble dry your electric blanket on low heat. This will take longer, but protects the electric wiring from damage.
• Never dry-clean an electric blanket. The harsh chemicals used for dry cleaning can damage your heated blanket and electric mattress pad. Most dry cleaners will know this, but you can avoid problems by washing your electric blanket at home.
• If your electric blanket looks smaller after washing, place it on a flat surface and gently smooth the fabric to its original shape. Once you’ve reshaped it, hang the electric blanket over a laundry line or clothes drying rack overnight.
• Never iron an electric blanket. The iron’s high temperatures can damage the wiring insulation and cause it to melt. If you need to remove wrinkles after washing your electric blanket, hang it over a shower rod or drying rack while it is slightly damp and let gravity pull the wrinkles out.
How to Store Your Electric Blanket
Always wash your electric blanket before storing it for the season. Once your blanket is completely dry, roll it up or fold it gently without creasing or compressing the wires. Then place it in a plastic storage container to protect it from pests and your electric blanket will be fresh and ready for you to use next winter.
