Knowing how to wash a heated blanket the right way is important for both safety and longevity. Because heated blankets contain electrical wiring and controllers, washing them incorrectly can damage the blanket or even create safety risks. The good news is that most modern heated blankets are washable—as long as you follow the correct steps.
In this guide, we’ll explain how to clean a heated blanket safely, whether you can wash it in a machine, how to dry it properly, and the most common mistakes to avoid.
Can You Wash a Heated Blanket?
Yes, you can wash a heated blanket, but only if you follow the manufacturer’s instructions carefully. Most electric and heated blankets sold today are designed to be machine washable, provided that all electrical components are removed before washing.
However, older models or damaged blankets may not be safe to wash. Always check the care label before proceeding.
Before Washing: Important Safety Checks
Before you wash a heated blanket, take a few minutes to prepare it properly.
✔ Unplug the blanket completely
Make sure the blanket is disconnected from the power source.
✔ Remove the controller and cords
Never wash a heated blanket with the controller attached. This is the most important step.
✔ Inspect for damage
If you notice frayed wires, burn marks, or exposed heating elements, do not wash the blanket. It may be unsafe to use.
✔ Check the care label
Some heated blankets require gentle washing or air drying only.
How to Wash a Heated Blanket in a Washing Machine
If the care label allows machine washing, follow these steps carefully.
Step 1: Use cold or lukewarm water
Set your washing machine to cold or warm water. Avoid hot water, as it can damage the internal wiring.
Step 2: Choose a gentle cycle
Use the delicate or gentle cycle to reduce stress on the heating elements.
Step 3: Use mild detergent
Avoid bleach, fabric softeners, or harsh detergents. These can break down the wiring insulation.
Step 4: Wash alone or with light items
Do not overload the washer. Heavy items can twist or damage the blanket.
This method answers the common question: how do you wash a heated blanket safely without damaging it—gentle handling is key.
Can You Wash an Electric Heated Blanket by Hand?
Yes, you can wash an electric heated blanket by hand, especially if the manufacturer recommends it.
To hand wash:
- Fill a tub with lukewarm water
- Add a small amount of mild detergent
- Gently agitate the blanket for a few minutes
- Rinse thoroughly without wringing or twisting
Hand washing is a good option if you’re unsure whether your blanket can handle machine washing.
How to Dry a Heated Blanket Safely
Drying is just as important as washing.
✔ Air drying (best option)
Lay the blanket flat on a clean surface or hang it over a drying rack. Make sure it is completely dry before reconnecting the controller.
✔ Low-heat dryer (if allowed)
Some blankets allow tumble drying on low heat for a short time, followed by air drying. Never use high heat.
⚠️Do not iron or dry clean a heated blanket.
Common Mistakes That Damage Heated Blankets
Avoid these mistakes to extend the life of your blanket:
- Washing with the controller attached
- Using hot water or high heat
- Twisting or wringing the blanket
- Using bleach or fabric softener
- Plugging it in before it’s fully dry
These errors are the main reasons heated blankets stop working after washing.
How Often Should You Wash a Heated Blanket?
You don’t need to wash a heated blanket frequently.
- Once or twice per season is usually enough
- Spot clean small stains when possible
- Always wash before storing it after winter
If you use your blanket daily, washing it every few months is reasonable.
Are Heated Blankets Safe After Washing?
Heated blankets are generally safe to use after washing, as long as:
- They are completely dry
- The controller is reattached properly
- There is no visible damage
Before regular use, plug it in and test it on a low setting for a few minutes.
When Should You Replace a Heated Blanket?
Consider replacing your blanket if:
- It no longer heats evenly
- The controller malfunctions
- You notice electrical damage
- It’s more than 8–10 years old
If you’re upgrading, you may want to look for newer models with improved safety features and washable designs.
