How to Wash an Electric Heated Blanket? | Safe Cleaning Steps

An electric heated blanket needs different care than a regular one, since it contains wiring that can break or short out if handled roughly. The process that works for most models is straightforward: unplug everything, wash gently, and dry fully before plugging it back in. Your blanket’s care label always overrides general advice, so check it first.

Steps For Machine Washing An Electric Blanket

Most electric blankets can go in a washing machine, but only if they’re prepped correctly. The single biggest mistake people make is skipping the setup, which leads to damaged wiring or a ruined controller.

• Unplug the blanket from the wall and let it cool completely.
• Detach the controller and power cord from the blanket itself. The cord should never enter the water.
• Set the machine to a gentle or delicate cycle with cool or cold water.
• Add a mild detergent — nothing with bleach or fabric softener.
• Give the blanket room to move freely in the drum. In a top-loader with an agitator, spread it evenly so the wiring isn’t stressed.

If your blanket’s label doesn’t say otherwise, this presoak approach is a safe template to follow.

Hand Washing When The Label Says No Machine

If the care label says hand wash only — or if your blanket’s wiring feels delicate — the tub method works just as well. It takes a little longer but gives you total control over how much the blanket gets agitated.

Fill a tub or large sink with cool to lukewarm water and add a mild detergent. Submerge the blanket and let it soak for several minutes, then gently squeeze and move it through the water — don’t scrub or twist. Drain the soapy water, refill with clean water, and repeat until the suds are gone. Press the water out by squeezing rather than wringing, then move on to drying.

One thing to know: some product manuals, including ones for heated underblankets, are more specific. They may direct you to machine wash inside a thin mesh laundry bag on a wool or gentle program at around 30°C (86°F), or to hand wash in lukewarm water for about 15 minutes. And a few explicitly warn against top-loading machines. Always defer to what came with your specific blanket.

How To Dry An Electric Blanket Safely

Drying is where most electric blankets get damaged. The wiring inside is sensitive to high heat, and using a blanket before it’s completely dry can be a fire hazard.

Air drying is the safest route for nearly every model. Lay the blanket flat on a drying rack or clothesline, and avoid hanging it by clothespins or by the cord, which can stress the internal wires. If the care label explicitly permits low heat, a tumble dry on the lowest setting works, but many manuals say line dry only.

Sunbeam’s instructions say to spin dry the blanket in the washing machine after the rinse cycle, then reshape it to its original size before drying. Other manufacturers recommend skipping the spin entirely or using a minimal spin to protect the wiring. Since guidance differs from brand to brand, the label is your final authority here. Whatever method you choose, don’t reconnect the controller or use the blanket again until it’s completely dry — inside and out.

What Not To Do With A Heated Blanket

The common mistakes are easy to avoid once you know them. Never wash the blanket while it’s plugged in, and never submerge the controller or cord. Skip hot water, bleach, and harsh detergents entirely. Don’t wring, twist, or use high-heat drying, and don’t hang the blanket by clothespins. If the cord, controller, or wiring looks damaged in any way, stop using the blanket altogether rather than risking a bigger problem.

One more thing worth knowing: not every electric blanket is machine washable, and some are hand wash only. The product category doesn’t decide the method — the care label does. If you’re shopping for a new one and washability matters, it’s worth checking the care instructions before buying. Our tested electric heated blanket roundup covers models you can actually clean without frustration.

For most blankets, the routine is the same: unplug, detach, gentle wash in cold water, and dry completely. Follow that sequence with a close eye on your care label, and your heated blanket will stay cozy for years.
