How To Wash A Heated Blanket?
To wash a heated blanket, unplug it first and remove every detachable cord, controller, and remote. Check the care label before choosing machine washing, hand washing, or spot cleaning.
If the label allows machine washing, use mild detergent, cool or cold water, and a gentle cycle. It is always best to avoid things like:
- Bleach
- Fabric softener
- Harsh stain removers
- Aggressive spin settings
After washing, reshape the blanket gently with your hands. Don’t twist it like a towel - dry it fully before reconnecting anything.
Pay close attention to the connector area because moisture can hide there. If any part still feels damp, you should wait. A warm bed is not worth electrical risk.

Can You Wash A Heated Blanket Without Damaging It?
Many heated blankets can be washed without damage, but only if the maker says they are washable. That answer matters because older electric blankets may not be built like newer washable heated blanket designs.
Some have detachable controls and protected internal wiring. But others may be too fragile, worn, or poorly sealed for water. Before cleaning electric blanket items, inspect the fabric, looking for issues like:
- Frayed areas
- Exposed wires
- Stiff lumps
- Scorch marks
- Cracked connectors
- Odd smells
If anything looks wrong, do not wash it yet - contact the manufacturer or replace the blanket. A damaged heated blanket should not be “saved” with a careful wash. For a simpler alternative, explore our custom fleece blankets for a warm, personalized throw at a great price.
Can Heated Blankets Go In The Washing Machine?
Some heated blankets can go in the washing machine, but not all models qualify. The care tag and manual have the final say - look for symbols or wording that says machine washable, gentle cycle, cold water, or tumble dry low.
If the label says spot clean only, follow that instead. Heated blankets use embedded heating wires and other electrical components that may not be shielded against water. Large washable heated blankets need a roomy washer so they can move without bunching into a tight ball.
Bunching can bend wiring and strain seams. If your machine has a delicate or low-agitation setting, use it. The wash should be short, gentle, and mild - this is not the load for heavy towels, jeans, or a high-speed scrub.
Can You Wash A Heated Blanket With Wires Inside?
You can wash a heated blanket with wires inside only when it is designed for washing. The wires in washable models are protected, but they are not indestructible. Treat them like something that needs respect.
Heated blankets have electrical parts, so this is more complicated than a duvet vs blanket discussion. Do not:
- Scrub wired areas hard
- Twist the blanket
- Wring it
- Crush it under heavy laundry
Use gentle movement and let water do most of the work. After washing, run your hands over the blanket, checking for lumps, kinks, bunched areas, or spots that feel different from before. If the texture has changed or a wire feels bent, stop using it until you know it is safe.
Can Washing Damage The Heating Parts Inside A Heated Blanket?
Improper washing can damage the heating parts inside a heated blanket. High heat, harsh cycles, bleach, wringing, dry cleaning solvents, and rough handling can all cause trouble.
Sunbeam’s own heated bedding instructions warn against bleach, dry cleaning, cleaning fluids, and wringers, and they also advise following washing instructions carefully. Washing and rubbing may affect heating performance in many models.
The care label reduces risk because it is written for that specific blanket. After washing, stop testing if the blanket:
- Smells burnt
- Heats unevenly
- Sparks
- Shows discoloration
- Trips the controller
Unplug it and stop using it. That is not being fussy - that is basic electrical sense.
Here’s a quick reference guide on what NOT to do:
| What not to do | Why it matters | What to do instead |
|---|---|---|
| Do not wash it without checking the care label first. | Heated blankets vary by model. Some are machine washable, some are hand wash only, and some should only be spot cleaned. | Read the care label or product manual before using water, detergent, or a washing machine. |
| Do not leave the controller, plug, or power cord attached. | Electrical controls are not designed to be washed and can become unsafe if exposed to water. | Unplug the blanket and remove every detachable cord, controller, and remote before cleaning. |
| Do not use bleach. | Bleach can damage the fabric, wiring insulation, and internal components. | Use a small amount of mild detergent unless the manufacturer says otherwise. |
| Do not dry clean it unless the label specifically says it is safe. | Dry cleaning solvents may damage the heating elements or insulation inside the blanket. | Follow the washing method named on the care label. |
| Do not wring, twist, or aggressively spin the blanket. | This can bend, kink, or break the internal wiring. | Press out excess water gently using clean towels. |

How Do You Dry A Heated Blanket Safely?
Drying is just as important as washing. A heated blanket must be fully dry before it is plugged in again. If the label allows machine drying, use low heat or air-only settings, and follow the time limit.
Many instructions suggest partial low drying, then finishing by air drying. If air drying, spread the blanket open over a drying rack or clean surface with good airflow.
- Do not hang it from sharp clips that pinch the wires.
- Do not stretch it to “make it dry faster.”
Gently reshape it while damp so it returns to its normal size. Check seams, corners, and connectors last.

Can You Put A Heated Blanket In The Dryer?
Some heated blankets can go in the dryer, but only when the care label allows it. Use low heat, air-only, or the exact setting named in the instructions. High heat can damage wiring, connector areas, fabric, and internal insulation.
Whirlpool notes that machine drying depends on the care tag and that heated blankets may need extra care because of their heating elements. If the instructions say to remove the blanket while slightly damp and finish air drying, do that.
It may feel slow, but it protects the blanket. Never use a hot dryer because you are in a hurry - heat shortcuts are where many problems begin. If you are cold and your blanket isn’t dry yet, try adding layers to your sleepwear or sleeping in socks.
Safe Ways To Dry A Heated Blanket Faster
To dry a heated blanket faster without high heat, start by pressing out water with clean towels. Lay the blanket flat between towels and press gently - do not twist. Then spread it open in a warm, ventilated room.
A fan can help move air across the fabric. A dehumidifier can help too if the room is damp. Turn the blanket over after a while so both sides dry evenly. Avoid radiators, space heaters, direct scorching sun, heated rails, or intense dryer settings. These can overheat small areas and stress the wiring.
Damp electrical textiles should never be powered on, even “just to test.” If you want something to keep you warm while you wait, consider custom knitted socks - keeping feet warm can make a big difference.
How Do You Remove The Cord From An Electric Blanket Before Washing?
Before washing, unplug the blanket from the wall. Then remove the controller cord from the blanket connection point if it is detachable. Do not yank it out - hold the connector area and separate it carefully, following the manual.
Before washing, check for things like:
- Cracks
- Looseness
- Dark marks
- Bent pins
Be sure to keep cords, plugs, remotes, and controllers away from water completely. They are not part of the wash, so place them somewhere dry while the blanket is cleaned. Flexible heating elements are durable, but the guidance in the care label is crucial.
Reconnect only when the blanket is fully dry and visually inspected. If the plug area feels damp, cool, sticky, or strange, leave it longer. The connector is one of the most important areas to check.
Can You Wash And Dry A Heated Blanket At Home?
Many people can wash and dry a heated blanket at home if the care instructions allow it. Think of the job as one connected routine, not separate steps:
- Unplug first
- Remove cords
- Inspect the blanket
- Wash gently
- Dry slowly
- Inspect again
- Reconnect only when fully dry
The way you wash affects the way it dries. A rough spin can twist the blanket and leave bunched wiring. A heavy wash can leave wetter seams.
If moisture remains near the connector, wait before testing. We know it is tempting to plug it in once the outside feels dry, but hidden damp spots are the concern. With bedding, it’s important to understand what a queen size blanket is and other dimensions, but the specifics of caring for heated blankets is an issue of actual safety.
Why Is My Heated Blanket Not Working After Washing?
A heated blanket may stop working after washing because moisture remains near the connector, the controller is loose, wiring was bent, or the safety system has shut it off. Heating elements can fail due to water exposure or damage from agitation.
First, make sure every part is fully dry. Then reconnect the controller firmly and follow the manual’s reset or testing steps. Some blankets display flashing lights when connections are not seated correctly. If it still fails, do not keep unplugging and replugging it in frustration.
Stop if you notice a burnt smell, sparks, overheating, buzzing, visible damage, or uneven heating. A blanket that behaves oddly after washing should be treated as unsafe until checked.

Learn moreHow Do You Clean An Electric Blanket By Hand?
Hand washing is gentler when the blanket is washable but you do not trust the machine. Fill a tub with cool water and mild detergent. Submerge the blanket without the cords or controls attached.
Let it soak for a short time, then move it through the water gently with your hands. Do not scrub wired sections or twist the fabric. Drain the water and rinse with clean cool water until all detergent is gone.
Lift the blanket carefully with both hands so the wet weight does not stretch the wires. Press out water with towels, then dry flat or spread open with good airflow. If you are cold during drying, consider custom contrast fleece robes for warmth.
How Often Should You Wash An Electric Blanket?
How often you wash an electric blanket depends on use. A blanket used nightly may need cleaning more often than one used on occasional cold evenings. Sweat, spills, pets, crumbs, and storage odors all change the answer.
A washable cover or electric blanket duvet cover can reduce full laundering because you can clean the cover more often than the blanket itself. Washing is important to remove mite allergens or odors and to maintain hygiene.
Spot clean small stains when possible instead of washing the whole blanket every time. Before seasonal storage, clean and dry the blanket fully so odors and dirt do not settle in. Store it loosely folded, not crushed under heavy bedding.

How Do You Wash A Sunbeam Heated Blanket Safely?
For a Sunbeam heated blanket, brand-specific instructions should override general advice. Check the Sunbeam care tag or product manual for your exact model.
Sunbeam’s heated bedding care page says to do the following:
- Pre-soak in mild soap and cold water.
- Wash on a delicate or gentle cycle for two minutes
- Rinse in fresh cold water
- Spin dry
- Gently shape back to size
Some Sunbeam materials and controls may differ by model, so do not assume every blanket follows the same timing. Verify cord removal, washer settings, dryer limits, and warnings before starting.
If the tag and website disagree, contact Sunbeam support before guessing. Alternatively, work with us to create a custom sherpa blanket that offers superb warmth and comfort without any electrical components, ensuring washing is straightforward.
