Electric blankets collect body oils, sweat, dust mites, and pet dander just like regular bedding, yet many owners avoid washing them out of fear of damaging the internal wiring. The good news: most modern electric blankets are designed to be washed. Knowing how to wash electric blanket properly keeps it fresh, extends its lifespan, and eliminates allergens that accumulate over a heating season. Follow these steps to clean yours safely.
Check the Care Label First
Before doing anything, read the manufacturer’s care instructions. Most electric blankets made after 2010 are machine-washable on a gentle cycle, but a few older or luxury models require hand washing only. If the care label is missing or illegible, check the manufacturer’s website using the blanket’s model number. Brands like Sunbeam, Beautyrest, and Biddeford publish washing instructions online for current and discontinued models.
If the wiring inside the blanket feels stiff, cracked, or bunched in spots, do not wash it. Damaged wiring can short-circuit when wet, and a blanket in that condition should be replaced, not cleaned. Inspect the blanket flat on a bed and run your hands over the surface to feel for any irregularities before proceeding.
Prepare the Blanket for Washing
Disconnect all cords and controllers from the blanket. Most electric blankets have detachable connectors near the edge. Remove the plug end from the wall and detach the controller module from the blanket itself. These electronic components must never be submerged in water.
Shake the blanket outdoors to remove loose debris, pet hair, and crumbs. Pre-treat any visible stains with a small amount of mild liquid detergent applied directly to the spot. Let the pre-treatment sit for 5-10 minutes, then gently blot with a damp cloth. Avoid rubbing aggressively, which could shift the internal wires out of position.
Machine Washing Instructions
Use a front-loading or top-loading machine without a center agitator. The agitator post in older top-loaders can twist and damage the internal wiring. If you only have an agitator-style machine, hand washing is the safer route.
- Set the machine to a gentle or delicate cycle with cold or lukewarm water, never exceeding 86 degrees F.
- Add a small amount of mild liquid detergent. Skip bleach, fabric softener, and OxiClean, as these chemicals can degrade the wire insulation over time.
- Place the blanket loosely in the drum. Do not wrap it tightly or bundle it up, as you want the water to flow freely through the fabric.
- Let the wash cycle run for 2-3 minutes only, then skip ahead to the rinse cycle if your machine allows it. A brief wash is sufficient since the blanket does not accumulate the heavy soil that sheets and towels do.
- Run one additional rinse cycle to ensure all detergent is removed. Residual soap can attract dirt faster and may cause the heating wires to smell when powered on.
Hand Washing Method
Fill a clean bathtub with enough cool to lukewarm water to fully submerge the blanket. Add one tablespoon of mild liquid detergent and swirl to dissolve. Lay the blanket flat in the water and gently press it down to saturate the fabric. Let it soak for 10-15 minutes, gently agitating by hand every few minutes.
Drain the tub and refill with clean, cool water for rinsing. Press the blanket to release soapy water without wringing or twisting. Repeat the rinse until the water runs clear. Carefully lift the blanket out, supporting its weight evenly to avoid pulling on the internal wires. A wet electric blanket is surprisingly heavy, so take your time.
Drying Your Electric Blanket
Spin the blanket in the washing machine on the lowest spin setting to remove excess water. Then transfer to a dryer set on the lowest heat or air-fluff setting. Tumble dry for 10-15 minutes, just enough to remove dampness but not enough to overheat the wiring. High heat can melt or warp the thin insulation around the internal wires, creating a safety hazard.
The ideal finishing step is to drape the blanket over a drying rack or clothesline for the final hour or two of drying. Spread it flat rather than folding it over, ensuring air circulates around the entire surface. The blanket must be completely dry, inside and out, before you reconnect the controller and plug it in. Using a damp electric blanket is a fire and shock risk.
How Often to Wash an Electric Blanket
Washing once per season, either at the end of winter before storing or at the beginning of the cold season before first use, is the standard recommendation. If you use the blanket nightly and have pets on the bed, twice per season is reasonable. Overwashing accelerates wear on the wiring connections and fabric, so resist the urge to clean it as frequently as regular bedding.
Between washes, spot-clean stains promptly and use a washable duvet cover or flat sheet over the blanket as a protective barrier. The cover catches most of the sweat, oils, and pet hair that would otherwise require a full wash. Simply launder the cover weekly with your regular bedding.
Storage Tips for the Off-Season
When heating season ends, wash the blanket following the steps above and ensure it is bone-dry. Roll the blanket loosely rather than folding it tightly, as repeated folding along the same crease lines can stress and eventually break the internal wires. Store it in a breathable cotton bag or a cardboard box, not a sealed plastic bin, which traps moisture and promotes mildew.
Keep the detachable controller and cord stored with the blanket so nothing gets lost over the summer. Avoid stacking heavy items on top of the stored blanket, which can compress and damage the wiring. A shelf in a climate-controlled closet is the ideal storage spot. Garages and attics with extreme temperature swings can degrade the wire insulation over time.
