Hub / Care and washing
Can you wash an electric blanket?
Yes. Every mains blanket we track is machine washable, and every one of them means something slightly different by it. The differences are where blankets die.
The short version is below; the step-by-step is washing an electric blanket. Wondering when to replace it? How long they last.

Caring for a Bedsure heated blanket
The one brand that publishes a wattage on everything, and what its preheat does.

Check priceYes. Detach the controller and the power cord first, wash on a gentle or delicate cycle in cool or lukewarm water, and either tumble dry on low for a short time or line dry. Never dry clean, never bleach, never wring it, and never use it while it is still damp. Those rules are common to every manufacturer in our set.
The one rule that breaks blankets
Detach the controller. It appears on every listing and every manual we read, and it is still the most common way a heated blanket is destroyed. The controller is an electronic module and it does not survive immersion. On most modern blankets the connector is a plug at one corner of the hem; on some it is a two-part cord that separates in the middle.
Sealy goes further than most and specifies the machine settings too: slow agitation and low spin speed, with dry cleaning, bleaching and wringing all prohibited by name. Those are the conditions that damage the element itself rather than the electronics, because the failure mode is mechanical. A heating wire that is twisted hard enough eventually cracks its insulation, and it will not tell you it has.
The dryer question
This is where manufacturers genuinely disagree and where generic advice is worst.
- Biddeford states plainly that its blankets are dryer safe and should be tumble dried on low heat.
- Westinghouse says tumble dry on low or line dry.
- Sealy prohibits dry cleaning and specifies a low-spin wash, and its guidance leans towards line drying.
- The consistent advice across all of them: a short low-heat tumble to remove most of the water, then finish flat or on a line. Nobody in our set endorses drying a heated blanket to completion on high heat.
One rule is universal and non-negotiable: do not use the blanket while it is damp. Westinghouse states it explicitly. Every other maker implies it. Water and a heating element in the same fabric is the one combination that has no upside.
How often, and what washing costs you
Less often than a sheet. A blanket that sits above your top sheet is not against your skin, and every wash cycle flexes the heating wire. Two or three washes a season is a reasonable rhythm for a bed blanket; a throw that lives on the sofa and gets sat on will want more.
This is also the honest tension in the category. Washability is the headline feature on every listing, and washing is one of the two things that shortens a heated blanket's life, the other being folding it hard for storage. Both are covered in how long do electric blankets last.
Storing it for the summer
The rule is the same as the folding rule, for the same reason: a crease is a stress point in the wire. Roll a heated blanket rather than folding it, store it somewhere dry and not compressed under other bedding, and do not put anything heavy on top of it. Full detail in storing a heated blanket.
Per-brand instructions
Generic advice is where blankets get ruined, because the differences between brands are exactly the parts people get wrong. We have the specifics for the two brands people search for most: Sunbeam and Bedsure.
Questions people actually ask
- Can you wash an electric blanket in the washing machine?
- Yes, with the controller and power cord detached first, on a gentle or delicate cycle in cool to lukewarm water with a slow spin. Never dry clean, never bleach, never wring it out.
- Can you put an electric blanket in the dryer?
- Usually, on low heat and for a short time. Biddeford states its blankets are dryer safe on low; Westinghouse says tumble dry low or line dry. What every maker agrees on is that you must not use the blanket until it is completely dry.
- How often should you wash a heated blanket?
- Less often than sheets. Two or three times a season for a bed blanket is reasonable. Each wash flexes the heating wire, so washing it weekly shortens its life for no real benefit.
- How do you wash a heated blanket with wires in it?
- The same way as any other, because the wires are why the rules exist: detach the controller, use a gentle cycle and a slow spin so the wire is not twisted, dry it flat or on low heat, and never wring it. The full sequence is on washing an electric blanket.
