How to Wash an Electric Heated Blanket?

An electric heated blanket can be washed safely, but the process is different from regular laundry. The blanket itself is usually fine to clean at home, but the wiring, controller, and cords need special handling. Get this wrong, and you risk damaging the heating elements or creating a shock hazard. The good news is that with the right steps, you can keep the blanket fresh without hurting it. Below is the method that works for most modern heated blankets, plus the warnings worth honoring.

Before You Wash: Prepping The Blanket

Preparation determines whether your blanket survives the wash. Start by unplugging the blanket from the wall and waiting for it to cool completely. Then remove the detachable controller and any cords. These components are electronic—they cannot be submerged with the fabric, and submerging them can ruin the blanket or pose a shock risk.

Once the electronics are out, check the care label sewn into the blanket’s edge. That label, not general advice, tells you what your specific model can handle. If it says “do not wash,” follow that instruction. If it gives washing guidance, the steps below align with what most manufacturers recommend.

Washing The Blanket: Cycle, Detergent, Water

Wash a heated blanket on a gentle cycle with cold or lukewarm water and a mild detergent. Sunbeam also notes that bleach should never be used. Maytag’s guidance matches the same core principles: unplug the blanket, remove the controller, use cool-to-warm water with a mild detergent, and avoid wringing or twisting the fabric.

The washing rules that appear consistently across official sources include:

• Unplug the blanket and disconnect the controller and all cords first.
• Use mild detergent—not bleach, and according to some guides, not fabric softener either.
• Set the machine to delicate, gentle, or wool cycle with short agitation.
• Avoid hot water, high spin speeds, wringing, twisting, and ironing.
• Never put the controller, cords, or power supply in the washing machine.

If your blanket is too large for your washer, or the label says not to machine wash, hand-washing in a clean tub or large sink with cool water and mild soap is the safe alternative.

Drying: The Step People Rush And Regret

Drying a heated blanket improperly is the most common cause of damage. The blanket must be completely dry before you reconnect the controller or use it again. Moisture inside the heating wires can cause shorts, and a damp blanket is both uncomfortable and unsafe.

Air drying is the safest option. Lay the blanket flat on a clean, dry surface or hang it over a shower rod, and let it dry fully—this can take a day or more depending on thickness. Maytag specifically advises hanging the blanket until it is completely dry before reuse. Tumble drying on a low or no-heat setting is acceptable for some models, but only if the care label permits it. High heat can melt or damage the internal wiring. Never iron a heated blanket, and never use it while it is even slightly damp.

Once the blanket is bone dry, reconnect the controller and cords, plug it in, and test it on a low setting for a few minutes before using it overnight.

Washability Varies By Model

Not every electric heated blanket is washable. Some are designed as “spot clean only,” and washing them voids the warranty or damages the wiring. The care label and the manufacturer’s manual are the only reliable guides for your specific blanket. When in doubt, spot-clean stains with a damp cloth and mild soap rather than risking a full wash.

The safest routine for any heated blanket is to wash it less often than regular bedding, use a removable cover if you want easier cleaning, and always give it time to dry fully. If you are shopping for a new blanket and want one that’s easy to keep clean, look for models with detachable controllers and machine-washable labels.

FAQs

Can you put an electric blanket in the washing machine?

Yes, if the care label says it is washable. Unplug the blanket and remove the controller and cords first, then wash on a gentle cycle with cold or lukewarm water and mild detergent. Never machine-wash the controller, cords, or power supply, and always air-dry the blanket completely before using it again.

What happens if you wash an electric blanket with the cord attached?

Washing the blanket with the controller or cord attached can damage the electronic components and create a shock or fire hazard. Water can get inside the controller and short-circuit it. Always remove all detachable electronics before washing, and only reconnect them once the blanket is completely dry.

Can you dry an electric blanket in a tumble dryer?

Yes, but only if the care label says it is safe. Use a low or no-heat setting and remove the blanket as soon as it’s dry. Air drying is the safest option for most blankets, since high heat can damage the internal wiring. Never use the blanket until it is fully dry.
