Heated blankets are great for staying warm and cozy, especially during chilly nights. But things can get a little confusing when it’s time to clean them. So, can you wash a heated blanket? Is it safe to toss one in the washer or dryer? Find out below.

What Is a Heated Blanket?

A heated blanket is basically a cozy blanket with built-in wires that warm up when plugged into a power source. These wires are safely tucked inside the fabric. Once you turn the blanket on, it heats up and spreads warmth across the surface. Most electric blankets let you adjust the temperature, so you can pick what feels right for you.

There are two types of heated blankets: electric and self-heating. Electric ones plug into a wall outlet, while self-heating blankets run on batteries. Either way, the goal is the same: keep you warm, whether you're in bed, on the couch, or just trying to relax.

Heated blankets can help with more than just cold nights. They also help ease muscle aches and joint pain by boosting blood flow. Plus, some find that the warmth helps reduce stress and makes it easier to fall asleep. However, they might not be the best fit if you’re a hot sleeper or have certain medical conditions, like poor circulation or nerve damage.

Safety-wise, modern heated blankets come with features like timers and sensors to prevent overheating. Just don’t use them with pets or small kids, and avoid layering too many covers on top. When used right, a heated blanket can be a safe and comfy way to stay warm and relaxed.

Can You Wash a Heated Blanket?

Yes, you can wash a heated blanket. However, you’ve got to be careful about how you do it. If the label says the blanket is machine washable, you're good to go with a gentle wash. Use cold or lukewarm water, a mild detergent, and the delicate cycle. Don’t use bleach, harsh chemicals, and high-speed spins.

On the other hand, some heated blankets can’t be machine-washed. If this is the case, hand-washing is the way to go. Fill a tub with cool water and mild detergent, gently swirl the blanket around, rinse well, and air dry flat.

Never twist, wring, or iron a heated blanket. You should also fold or roll it loosely to protect the wires inside when storing. 

Heated Blankets vs. Thermal Blankets: What's the Difference?

Heated blankets are perfect for staying warm at home. They plug into a wall outlet or run on batteries, and they use internal wires to generate heat. You can adjust the temperature and enjoy steady warmth while you sleep, watch TV, or relax on the couch. But what happens when there’s no power or you’re outside in the cold? That’s where thermal blankets come in.

Thermal blankets like the Prepared Hero Survival Bag don’t need electricity. They’re made from special materials designed to trap and reflect your body heat. These emergency blankets are thin, lightweight, and easy to carry. They’re ideal for emergencies, camping, or power outages. While they won’t feel warm when you touch them, they’re incredibly effective at keeping you from losing heat when it matters most.

Both types serve different purposes. A heated blanket is great for everyday comfort, but a thermal blanket is a must-have for your wilderness survival and car emergency kit. Whether you’re planning a cozy night in or prepping for the unexpected, having both on hand means you’re covered no matter what. One keeps you comfortable now, while the other keeps you safe later.

How to Wash a Heated Blanket By Hand

Washing a heated blanket by hand is easy, but you must be gentle. Here’s how to  wash a heated blanket by hand properly: 

1. Check the Label and Unplug Everything

Before anything else, read the care tag to make sure hand-washing is allowed. Then, unplug the blanket and detach the controller or power cord. Never submerge these electrical parts in water. If your blanket has stains, gently spot-clean using a soft cloth, sponge, or toothbrush with a bit of mild detergent.

2. Set Up Your Wash Area

Next, fill a clean tub or large sink with cool to lukewarm water. Add a small amount of mild detergent and swish the water around until it’s fully mixed. Make sure the water isn’t too hot, or you could damage the heating elements.

3. Wash the Blanket Gently

Place your blanket in the water and let it soak for 10 to 15 minutes. Then, lightly move it around with your hands to help loosen dirt. Don’t scrub too hard, just enough to clean the fabric without stressing the wires.

4. Rinse Until Clean

Drain the soapy water and refill the tub with clean water. Rinse the blanket thoroughly. You may need to do this a couple of times to get all the soap out.

5. Dry It Properly

Gently squeeze out extra water, but don’t twist or wring the blanket. Lay it flat on a drying rack or hang it over a clothesline or shower rod. Let it air dry completely before using or storing.

How to Wash a Heated Blanket By Hand Using a Washer

You can clean a heated blanket using a washer, but you have to do so carefully. You should also check the label first. Here's how to wash a heated blanket using a washer properly: 

1. Check the Care Label First

Before anything else, read your blanket’s care tag. Not all electric blankets are washer-safe. If yours is, follow the instructions below.

2. Unplug and Remove the Controller

Unplug your heated blanket and remove the power cord or controller. These parts should never go in the washer.

3. Spot-Clean If Needed

If your blanket has visible stains, treat them before washing. Wet the spot, dab on mild detergent, and let it sit for about 20 minutes. Then gently rub with a toothbrush or cloth, rinse, and blot with a towel.

4. Load the Blanket Into the Washer

Next, place your blanket loosely in the washer. Don’t ball it up. For top loaders, wrap it around the agitator. For front loaders, lay it in evenly. If it’s a large blanket, wash it alone. You can add towels to balance the load if needed.

5. Use a Gentle Wash Setting

Choose a delicate or gentle cycle with cool or lukewarm water and a mild detergent. Doing this protects the inner wires while still getting the blanket clean.

6. Dry It the Right Way

Gently squeeze out excess water after washing. Don’t twist or wring it. Lastly, lay the blanket flat to air dry completely before plugging it back in.

How to Spot Clean a Heated Blanket

Spot cleaning your heated blanket is a quick way to deal with small messes without throwing the whole thing in the wash. It’s perfect for food spills, coffee drips, or anything else that lands on your blanket unexpectedly.

1. Unplug Before You Clean

Always unplug your blanket and remove the controller first. Never clean it while it’s still plugged in.

2. Blot the Stain Quickly

The sooner you tackle a stain, the easier it is to remove. Use a clean, absorbent cloth to blot the area. Don’t rub, or you’ll push the stain deeper.

3. Use a Mild Detergent or Stain Remover

Spray a gentle, oxygen-based laundry stain remover on the spot. If you don’t have that, a little mild detergent and water will do. Blot again with a towel to lift the stain and soak up moisture.

4. Rinse and Air Dry

Use a clean, damp cloth to wipe away any detergent left behind. Let the blanket air dry completely before plugging it back in.

How Often Can You Wash a Heated Blanket?

Wash your heated blanket once a month during cold seasons. If you’re not using it a lot, washing it once or twice per season should be enough. 

You should also wash it before storing it away for the summer. Doing this keeps it clean and ready for next time. Just make sure to check the care label for washing instructions specific to your blanket.

Go easy on the heat to help your blanket last longer. Use a gentle cycle with cool water and mild detergent. Alternate between air drying and low-heat tumble drying if your blanket allows it. Avoid ironing or tightly folding it because it can mess with the internal wiring. For small messes, just spot clean instead of tossing the whole blanket in the wash.

Can You Put Heating Blankets in the Dryer?

You might be able to put your heated blanket in the dryer, but always check the care label first. Some blankets are dryer-safe on a low or air-fluff setting, while others are not. High heat can damage the wires inside and even turn your blanket into a fire risk.

Use the lowest heat setting and keep the drying time short if your blanket’s label lets you put it in the dryer. Still, air drying is usually the safest route. Lay the blanket flat or hang it over a clothesline to let it dry gently without stressing the wiring.

Skip the laundromat dryers, too. They often run too hot, even on the lowest settings. When in doubt, air dry it to be safe.

How Do You Remove the Cord From an Electric Blanket for Washing?

Always check the care label and follow the manufacturer's instructions before washing your heated blanket. Most modern electric blankets have a detachable cord and controller that you can safely remove before cleaning. Look for the connector (usually at the foot of the blanket) and gently press the release button or squeeze the sides to unlock it. Then, pull the cord away from the blanket without forcing it.

Once the cord and controller are removed, inspect both ends to make sure they’re clean and undamaged. If your blanket has a permanently attached cord, don’t try to remove it. Instead, keep the electrical parts out of the water and handwash only the fabric areas.

Never get the cord or controller wet. Always air dry it flat, whether you’re washing it by hand or using the washing machine. 

Why Is My Heated Blanket Not Working After Washing?

If your heated blanket isn’t working after washing, it’s likely because of damage to the heating wires or moisture that didn’t fully dry. Washing can sometimes cause the thin wires inside to break, especially if the blanket was twisted, folded too tightly, or not washed according to the care label.

Another reason could be that it wasn’t completely dry before plugging it in. Even a little leftover moisture can mess with the electrical parts and stop the blanket from heating up.

Sometimes it’s just a simple error, like using the wrong settings or not fully connecting the cord. Check for damage, let it dry out fully, and test it in a different outlet. If nothing works, reach out to the brand’s support team or a technician.

Conclusion

Taking care of your heated blanket doesn’t have to be tricky. Whether you're spot-cleaning, hand-washing, or using a machine, just follow the care label and handle it gently. Always unplug it before cleaning, and let it dry completely before using it again. With the right care, your heated blanket will stay clean, cozy, and working properly all season long.
