Yes, most electric blankets are washable, but only on a gentle, cold-water cycle with the cord removed before any part of the blanket gets wet.
Throwing a heated throw into a hot wash with a spin cycle is the fastest way to ruin the internal wiring. The safe approach for how to wash an electric blanket comes down to one rule: follow the sewn-in care label and the user manual, because every model differs. Still, a few ground rules apply across nearly every brand, and they are simple enough to remember even without the paperwork in front of you.
What To Do Before The Blanket Touches Water
Unplug the blanket first, then remove the controller and any attached power cord. Sunbeam’s care guidance and other manufacturer notes are consistent here: those parts are not waterproof, and submerging them can damage the device or create a shock risk. Set the controller aside and keep it dry for the whole process.
Check the care label before doing anything else. If it says “do not wash,” stop there and spot-clean instead — some heated blankets are only meant for surface cleaning. If it permits washing, move on.
What Wash Cycle And Water Temperature Work?
Cold or lukewarm water and a delicate cycle are the universal safe defaults. Their method also tells you to skip bleach entirely and to gently pull the blanket back to its original shape afterward.
Some manufacturer manuals describe machine washing only if the blanket fits loosely in a domestic washer, using a wool or delicates cycle, water below 40°C, and a mild wool detergent or soap flakes. Hand washing in lukewarm water is the gentler alternative and works for anyone worried about the machine tugging at the wiring. Either path works; the point is to avoid hot water, harsh detergent, and a long agitated cycle.
Drying Without Damaging The Heating Wires
Drying is where most blankets get ruined. Do not wring or twist the fabric, and do not use a high-heat commercial dryer. The safe pattern across official manuals is air-drying or line-drying until the blanket is completely dry, with some brands permitting a brief low-heat tumble cycle.
Reconnect the controller only after the blanket is 100% dry. Plugging in a damp heating element invites shorts and uneven heating. If the blanket comes out of the wash feeling lumpy or the wires have shifted, smooth the fabric flat and let it air-dry completely before you even think about powering it on.
Three Mistakes That Shorten An Electric Blanket’s Life
- Bleach and fabric softeners leave residue that can break down the insulation around the wires over time.
- Wringing, twisting, or a high-spin cycle can crimp or snap the internal heating elements.
- Washing a blanket labeled “spot clean only” at all — official guidance consistently says to follow the label rather than a generic method.
Most heated blankets handle gentle washing well when you stick to cold water and a short cycle.

Just remember that whatever model you own, the care label is the final word on how to wash an electric blanket.
FAQs
Can you put an electric blanket in the dryer?
Some manuals allow a brief, low-heat tumble dry, but air-drying or line-drying until completely dry is the safest choice for most models. High heat can melt the wiring insulation, so if the label does not explicitly permit machine drying, hang it up instead.
Why does my electric blanket have lumps after washing?
Lumps usually mean the internal heating wires have shifted or bunched up from a rough cycle or wringing. Gently reshape the blanket while it is damp and lay it flat to dry. If the wires stay bunched after drying, the blanket may be unsafe to use and worth replacing.
How often should you wash a heated blanket?
Wash it only when it is visibly soiled, not on a schedule. Most care guides suggest a gentle wash once or twice a season at most, because every cycle adds wear to the wiring. Spot-clean small marks with a damp cloth to stretch the time between full washes.
