    Electric blankets are one of the most efficient ways to stay warm during colder months. They work through a network of internal wires that regulate the blanket's heat.  Many people wonder whether an electric blanket can be washed safely because of its built-in heating elements.

    However, electric blankets can be washed safely when proper care instructions are followed. Most recent heating blankets are designed to withstand machine washing. This article further explores how a heated blanket can be safely washed.

    How to Wash a Heated Blanket?

    Below are detailed steps to wash a heated blanket. Following this, make sure the blanket is washed thoroughly without damaging its mechanism.

    Read the Care Label

    Prior to washing, check the care label on the blanket for the manufacturer’s cleaning instructions. Although most recent electric heated blankets are suitable for machine washing, it is important to check whether specific guidelines are provided. This includes wash temperature and cycle settings.

    Prepare the Blanket

    The next important step is to prepare the blanket. All debris and loose remnants on the blanket must be removed by thoroughly shaking it.  Heated blankets have components such as cords and controls that must be removed before placing the blanket in the washing machine.

    Spot Clean Any Stains

    Make sure to check the blanket for any stains. They should be pretreated before the full wash. The steps below outline how to spot clean stains effectively:

    • Dampen the stained area and dab a small amount of mild detergent onto it.
    • The detergent should be left to sit on the stain for 20 minutes.
    • Use a warm, damp cloth to pat the stain. If not, use a toothbrush to gently rub it off.
    • Next, rinse the area and press it with a towel to absorb excess moisture.
    • The process can be repeated 2-3 times until the blanket is completely dry.

    Load the Washing Machine

    For high-efficiency washing, it is best to place the blanket loosely in the drum. However, it should be spread evenly around the drum for standard washers with a central agitator. A few non-lint-producing towels or sheets may also be added to the load to keep the machine balanced.

    Add Detergent

    After you put the blanket in the machine, add a mild detergent to the dispenser.  It can also be directly poured into the tub if the machine does not have a dispenser.

    Instructions on the package should be followed to know the amount of detergent required for washing. It is best to avoid bleach and fabric softener at any point during the process.

    Choose the Correct Washer Cycle

    The washer should ideally be set to a short or gentle cycle. If the machine allows for the final speed to be adjusted, it should be reduced to the lowest available setting. Excessive force during the spin cycle can put unnecessary strain on the blanket's internal wiring.

    Gently Dry the Blanket

     Set the dryer to a cool or air-only setting, and partially dry the blanket for approximately 20 minutes. You can remove it while it is still slightly damp, and allow it to finish drying on a clothesline or drying rack.

    Avoid drying the heated blanket in high heat, because it can cause the blanket to shrink and may damage the insulation around the internal wires. The dryer should also be large enough to allow the blanket to tumble freely during the cycle. If the dryer is not large enough, a laundromat dryer set to cool or air-dry only can be used.

    Most electric heated blankets are suitable for hand washing, but the care label should be read before washing. This works well for homeowners who do not have access to a large-capacity washer or dryer. Here are detailed steps on how to wash a heated blanket by hand:

    • Before washing, the blanket should be unplugged, and the controller and cord must also be fully removed.
    • A bathtub or large sink should be filled with cool to warm water. To this, add a small amount of mild detergent and mix well until foamy.
    • The blanket should be submerged completely and left to soak for several minutes, then shaken.
    • After cleaning, the soapy water should be drained, and the tub refilled with clean water. The blanket should be rinsed by swishing it through the fresh water. This step can be repeated until the water runs clear with no trace of soap.
    • Excess water can then be squeezed out of the blanket. Make sure not to wring or twist it, as this may damage the internal wiring.
    • The blanket can be hung to dry on a drying rack, over a clothesline without clothespins, or even over a shower rod. However, make sure that the shower rod is sturdy enough to handle the load. The blanket must be left to dry completely before it is plugged in and used again.

    Conclusion

    Caring for an electric blanket is not a highly complicated process. It simply requires careful consideration of the care label and other manufacturer instructions. Disconnecting all electrical components before washing the blanket is important for safety. With the right approach, the blanket can be kept clean and in good condition for a long time.
