How do you wash a heated electric blanket? Expert advice

For those who have tried to lower heating costs, you may have turned to trendy, fluffy electric throws during the colder months of the year.

But after long, dreary winter spells, you might be wondering if and how you can safely wash them in a washing machine to give them a new lease of life, especially when it comes to getting rid of any musty smells and stubborn stains.

With this in mind, we asked the experts for their recommended advice and compiled a trusty how-to guide when it comes to cleaning heated blankets properly.

Energy saving tips – what works and what’s just a myth

Can you wash electric blankets in a washing machine?

Scott Byrom, energy expert at The Energy Shop explained: “In most cases, yes – modern electric blankets are designed to be machine washable, as long as you detach the controller and power cable first.

“Once unplugged, treat it a bit more gently than your usual bedding. 

“Always be sure to check the manufacturer’s guide and the wash label on the blanket itself.

“If your blanket is washing machine-safe, always be sure to keep the temperature to 30°C max, and use a mild detergent.

“Always avoid bleach or fabric softener, as these can damage the internal wiring. A shorter wash is best to avoid unnecessary strain.”

Scott added: “Those that own a heated blanket containing insulated wiring within them should be aware of aspects such as harsh chemicals, high temperatures and fast motions, such as sharp twists and spins”.

Additionally, he said those looking to wash electric blankets should first ensure the blanket is disconnected from all electricity sources for safety reasons.

Scott continued: “Following that, it’s worth examining any stains or bits of dirt to see if they can be spot cleaned, and if so, apply lukewarm water and a mild detergent to a localised area.”

However, if spot cleaning does not suffice, and your heated blanket is machine washable, simply wash it on the recommended setting, which is likely to be a low temperature, delicate cycle, Scott advised.

If your heated blanket cannot be cleaned in a washing machine, Scott further detailed: “For heated blankets that are not machine washable, wash by hand using lukewarm water and a mild detergent, rinsing thoroughly and ensure all detergent is removed whilst avoiding wringing out the blanket to avoid damaging any metal wiring.”

7 steps to cleaning your heated blanket properly and safely according to an expert

In agreement with Scott, smol’s sustainable cleaning guru, Catherine Green has offered an additional seven top tips when it comes to cleaning your electric blanket safely.

Unplug and disconnect

Before cleaning your electric blanket, unplug it from the power source and remove any cords or controllers. Ensuring the blanket is completely disconnected is key to cleaning safely.

Check manufacturer instructions

Refer to the manufacturer guidelines for specific cleaning recommendations – a lot can be machine washed, but some may require hand washing or spot cleaning.

Tackle stains

For localised stains use a stain remover, like smol’s bleach-free stain gel. Apply a small amount to the affected area and gently rub with a soft cloth or sponge. Alternatively, apply a weak-ish solution of laundry detergent and warm water to the stain with a cloth, and then use another clean, damp cloth to rinse out.

Machine washing

If machine washing is safe for your electric blanket, remove all cords and controls and use a gentle, cold-water cycle. Catherine recommends smol laundry capsules, which don’t contain bleaching agents or conditioners.

Rinse thoroughly

Ensure thorough rinsing to remove all detergent residue- multiple rinse cycles may be necessary to achieve this.

Dry carefully

As previously mentioned by Scott from The Energy Shop, Catherine also clarifies you must never wring out or twist the electric blanket as you may damage the wiring.

Instead, gently press out excess water and then air-dry the blanket on a flat surface.

Avoid using heat sources like radiators or tumble dryers, as they can damage the electrical components.

Reconnect and test

Once the blanket is completely dry, reconnect the cords and controllers, following the manufacturer’s instructions.

Test the blanket to ensure it functions correctly before use – if the shape has been changed or the wiring damaged, a more gentler hand wash may correct things.
