The Right Way to Wash a Heated Blanket

Heated blankets are a great way to stay warm, especially during winter. These blankets have electrical wiring that, when connected to a power source and turned on, warm the fabric. Because of this electrical component, cleaning a heated blanket can be tricky. In addition to reading your manufacturer's instructions for guidance, use our tips to help you safely machine- and hand-wash, as well as dry your heated blanket.

How Often to Wash a Heated Blanket

Wash your electric blanket at least once or twice per season. These blankets are used more frequently during colder months, so you may need to wash yours more often based on frequency of use, says Kathy Cohoon, the director of franchise operations of Two Maids.

Before Getting Started

Most heated blankets can be cleaned in the washing machine or by hand, but make sure you read the manufacturer's care instructions before getting started. "Some electric blankets may have specific requirements," says Alicia Sokolowski, the president and co-CEO of AspenClean. "In many cases, electric blankets with removable controls and cords can be machine washed, while others may require spot cleaning or hand-washing."

Materials Needed

Make sure you have these materials on hand before getting started.

• Mild detergent
• Water
• Basin or bathtub
  

How to Machine-Wash a Heated Blanket

If your heated blanket allows it, detach the controls and cords, says Sokolowski. Otherwise, you may not be able to put it in the washing machine. Some newer heated blankets are designed to withstand machine-washing, but just be sure to check the manufacturer's care instructions first.

1. Unplug your heated blanket and disconnect the controls and power cord.
2. Pre-treat stains by adding a small amount of natural detergent to the problem area and dabbing with a clean microfiber cloth.
3. If it's a large blanket, wash it separately to ensure it has enough room to move around.
4. Launder on the delicate cycle with cold water and mild detergent.
5. Squeeze out excess water from your blanket gently. Avoid wringing or twisting, as this can damage the wiring.
6. Lay your blanket flat to air dry. Wait until it's completely dry before plugging it back in.
   

How to Hand-Wash a Heated Blanket

Like you did when machine-washing, detach the control and cord from the heated blanket and check the manufacturer's care instructions to ensure your blanket can be cleaned by hand.

1. Unplug your heated blanket and disconnect the controls and power cord.
2. Pre-treat stains by adding a small amount of natural detergent to the problem area and dabbing with a clean microfiber cloth.
3. Fill a basin (or clean bathtub) with lukewarm water.
4. Add a small amount of natural detergent to the basin (or bathtub)
5. Agitate the water a bit and fully immerse your blanket into the water.  
6. Allow your blanket to soak in the soapy water for 10 to 15 minutes.
7. Lightly rub the fabric with your hands to hand wash the blanket.
8. Drain the soapy water, refill the basin (or bathtub), and rinse your blanket.
9. Gently press or squeeze out excess water from the blanket. Avoid wringing or twisting, as this can damage the wiring.
10. Lay your blanket flat to air dry. Wait until it's completely dry before plugging it back in.

Can You Put a Heated Blanket in the Dryer?

Read your blanket's care instructions before putting it in the dryer. While many electric blankets can go into the dryer on the lowest heat setting, it's best to opt for air drying. "Excessive heat will damage the wiring," says Cohoon. "Air drying is the safest method."

Tips for Maintaining an Electric Blanket

Keep these tips in mind when caring for your heated blanket.

• Store the blanket in a cool, dry place when not in use.
• Avoid folding the blanket tightly to prevent damage to the wiring, says Cohoon.
• Pay attention to the cords and connectors. If they start looking frayed or worn, it might be time to purchase a new blanket.
• Read and follow the care instructions and guidelines from the manufacturer.
• Inspect regularly for stains (but also for signs of wear). 
• Address spills promptly. You don't want the liquids to penetrate the fabric, says Sokolowski.
