Can You Wash an Electric Blanket? 

You can wash most electric blankets. Modern electric blankets are designed to be machine-washable, with insulated wiring that can withstand gentle cleaning cycles. However, older models or certain high-end versions may require hand-washing only to maintain their functionality. 

The key concern when washing an electric blanket is preventing damage to the internal wiring. Submerging it in water for too long, using harsh detergents, or exposing it to high heat can weaken the electrical components. Most manufacturers recommend using a mild detergent and a gentle wash cycle to keep the blanket clean without compromising safety. 

When wondering if you can wash an electric blanket, many people worry that washing an electric blanket could lead to electrical hazards, but as long as the blanket is completely dry before being plugged in, and you don’t wash the cord that comes with the blanket, it’s safe to use. Proper care can also extend the lifespan of the blanket, ensuring it remains warm and effective for years to come. 

What Is the Best Way to Wash an Electric Blanket?  

The best way to wash an electric blanket is to follow the manufacturer’s care instructions. Generally, modern electric blankets can be machine-washed using a gentle or delicate cycle with cool to warm water and a mild detergent.  

Avoid using bleach or fabric softeners, as they can damage the blanket’s internal wiring. After washing, it’s recommended to air-dry the blanket by laying it flat on a drying rack something parallel.  

While you can dry your electric blanket in the dryer, it’s generally recommended to dry at a low heat and only for a few minutes and to let the blanket dry naturally.  

Materials Needed to Wash an Electric Blanket 

Washing an electric blanket is a simple process. Most electric blankets will come with their own washing instructions since each brand of blanket is different. But in the case your model doesn’t come with specific instructions; to wash your electric blanket, you’ll typically need the following materials: 

• Mild detergent: Choose a gentle laundry detergent free from bleach and fabric softeners to protect the blanket’s wiring.  

• Washing machine or large basin: Depending on the manufacturer’s instructions, you may use a washing machine or hand-wash the blanket in a bathtub or large sink.  

• Drying rack or clothesline: For air-drying the blanket flat to maintain its shape and prevent damage to internal components. 

How to Clean an Electric Blanket in a Washer 

Before washing, read the manufacturer’s instructions on the care label to ensure the blanket is machine-washable and to determine the recommended settings. If you don’t have specific written instructions, start by disconnecting and unplugging the blanket and detach any controllers or cords.  

Be sure to inspect the blanket for visible damage, such as exposed wires or scorch marks. If you see any of these, do not wash your blanket in a washer as this could ruin and break the electrical function of your blanket. 

 If there are stains, apply a small amount of mild detergent directly to the affected areas and gently blot with a clean cloth to remove them. For most washing instructions, the cycle length and settings recommended for washing an electric blanket won’t be enough to fully remove stains. 

Next, set your washer setting and place the blanket loosely in the washing machine to allow for proper movement during the cycle.  Use a gentle or delicate cycle with cool to warm water and add a mild detergent. Avoid bleach and fabric softeners, as they can damage the blanket’s internal wiring. After washing, gently squeeze out excess water without wringing. 

How to Clean an Electric Blanket by Hand 

Confirm that hand-washing is recommended by the manufacturer by reading the care instructions. Hand washing your electric blanket is the most recommend method for blanket brands. 

Like with washing your blanket in the washer, be sure to unplug the blanket and remove any controllers or cords. Check for visible damages, such as exposed wires or scorch marks and cover any exposed areas you may see as a safety to avoid electrical shock when prewashing stains. 

For bigger stains, apply a small amount of mild detergent to any stained areas and gently blot with a clean cloth. To wash your entire blanket, fill a bathtub or large basin with lukewarm water and add a small amount of mild detergent, mixing it to create a soapy solution.  

Submerge the blanket in the soapy water and let it soak for 10 to 15 minutes. Gently agitate the blanket by hand to clean it, avoiding twisting or wringing, which can damage the internal wiring.  

After 10-15 minutes, drain the soapy water and refill the basin with clean water. Rinse the blanket by gently pressing out the soapy water. Repeat this process until all detergent is removed.  

Can You Dry an Electric Blanket? 

Yes, you can dry an electric blanket, but it’s essential to follow proper guidelines to maintain its functionality and ensure safety. Air-drying is the safest method when it comes to drying an electric blanket. Lay the blanket flat on a drying rack or clothesline, ensuring it’s evenly supported to prevent stretching. Allow it to air dry completely before reconnecting any power components.  

Some electric blankets are designed to withstand machine drying. If the manufacturer’s instructions permit, use a low-heat or air-dry only setting on your dryer. Avoid high heat, as it can damage the internal wiring.  It’s advisable to partially dry the blanket in the dryer for about 20 minutes and then remove it while it’s still damp to finish air-drying.  

Keep in mind that excessive heat can damage the blanket’s wiring and insulation. Before plugging in and using the electric blanket, make sure it’s thoroughly dry to prevent electrical hazards. Wait at least overnight to make sure your sheet is completely dry. 

Here’s How I Washed Our Electric Blanket 

To help you solve if you can wash an electric blanket, we’ve done the work for you! Our Senior Digital Marketing Assistant, Jenna, has the scoop on how she washed her electric blanket:  

For this process, I washed a black and white Biddleford Blanket following these washing instructions printed on the blanket itself: 

”Wash by hand or as follows inan  automatic washer using slow agitation and normal spin speed. Fill washer with warm water, add minimal detergent and soak for five minutes. Agitate gently for two minutes. Spin. Fill for cool rinse. Agitate one minute. Spin. Dry in automatic dryer five minutes on low heat or air dry. Remove from dryer, stretch to original size and drape to finish drying.” 

Note that all electric blanket washing & drying instructions are different, and exact instructions will vary by brand. 

Here is a photo of the blanket we’re cleaning and the detergent I used during this cleaning process.  

I used this brand from Costco (Suavitel) and only used about 2 tablespoons of detergent to wash this blanket. Before I washed this blanket, I of course, unplugged the cord from the blanket and checked for frays in wires before cleaning. I checked the blanket again for bigger stains, I was planning on doing some spot cleaning before the full wash, but the blanket didn’t have any.  

Before I started the cycle, I used around two tablespoons of detergent. The instructions for cleaning this blanket stated using a cycle with warm water and washing the blanket for 10 minutes on a slow cycle would do the trick to wash it. 

My washer doesn’t have a “set your time” setting on it so, I set it for quick wash, with warm water and monitored the cycle for 10 minutes and took the blanket out. 

The blanket was still pretty wet so I lightly squeezed the water out before putting it into the dryer. I set my dryer to 10 minutes and applied low heat to dry out my blanket. 

After drying, I spread the blanket out on a parallel surface to air dry. As a safety for the wiring I left my blanket out to dry for 48 hours instead of 12. After that period, the blanket is working well and smells great! So, yes, you can wash an electric blanket! 

How Often Should You Wash a Heated Blanket?  

You should wash your heated blanket every two to four weeks if used regularly, especially during colder months. This helps maintain cleanliness by removing sweat, body oils, and dust. If you only use the blanket occasionally, washing it once per season may be sufficient. 

For people with allergies or sensitive skin, more frequent washing (every one to two weeks) can help reduce allergens like dust mites and pet dander. To minimize wear and tear, consider spot-cleaning small stains between washes instead of doing a full wash cycle every time. Always follow the manufacturer’s cleaning guidelines to prevent damage and extend the lifespan of your electric blanket. 

Common Mistakes to Avoid When Washing an Electric Blanket 

Proper cleaning of your electric blanket ensures longevity and safety. Because electric blankets are considered an electric appliance, avoid these mistakes when washing: 

1. Always wash your electric blanket in cool or warm water. Hot water can damage the internal wiring and insulation.  
2. Opt for a gentle or delicate cycle to prevent unnecessary agitation that could harm the heating elements.  
3. Avoid dry cleaning electric blankets unless specified by the manufacturer, as dry-cleaning chemicals can deteriorate wire insulation.  
4. Do not wring or twist the blanket. Instead, gently squeeze out excess water and air-dry or use a low-heat dryer setting.  
5. Always consult the care label for specific washing and drying guidelines to prevent damage and perform any other step you might have missed. 

Do Electric Blankets Use a Lot of Electricity? 

Compared to other appliances in the home, electric blankets do not use a lot of electricity compared to other heating options. They are designed to be energy-efficient, typically consuming 50-200 watts per hour. 

Unlike space heaters, which can use 750 to 1500 watts per hour, electric blankets focus heat directly on the user rather than warming an entire room. This targeted heating approach reduces overall power consumption while still providing effective warmth. 

Additionally, many modern electric blankets come with adjustable heat settings and automatic shut-off features, allowing users to optimize energy use by lowering the heat level once the bed is warm or setting a timer to turn off after a few hours.  

In short, an electric blanket doesn’t use a lot of electricity as long as you use it strategically, such as preheating the bed before sleep to further help minimize electricity usage. Compared the second best targeted heating alternative (the space heater), a heated blanket burns 1.3 kWh less electricity per hour. 

At around 100W of electricity, electric blankets use significantly less energy than space heaters or central heating.  Electric blankets aim to warm your body directly rather than heating the air, which minimizes energy waste. 

Are Electric Blankets Safe? 

Electric blankets are generally safe when used correctly and maintained properly. Modern electric blankets come with built-in safety features such as auto shut-off, overheat protection, and temperature control settings to reduce risks. However, like any electrical appliance, misuse, wear and tear, or manufacturing defects can pose safety concerns. 

To ensure safety with your electric blanket, always follow the manufacturer's guidelines for use, cleaning, and storage. Be sure to regularly inspect your blanket for any signs of damage or malfunction and avoid using electric blankets on infants, elderly individuals with reduced heat sensitivity, or people with certain medical conditions (such as diabetes or nerve disorders). 

Lastly, never leave an electric blanket on overnight unless it has an auto shut-off feature to prevent overheating.
