How to Wash a Heated Blanket Safely (Without Damage)
Your heated blanket is a sanctuary of warmth and comfort. But washing an electric appliance can feel risky. This definitive, safety-first guide walks you through every step to clean your heated blanket correctly, protecting its wiring and preserving its cozy lifespan.
There’s nothing quite like the pre-warmed hug of a heated blanket on a chilly September evening. But over time, our favorite comfort items collect dust, allergens, and body oils. While cleaning is essential for hygiene, washing a blanket filled with electrical wires requires a careful, methodical approach. One wrong step—like using high heat or twisting the fabric—can lead to irreparable damage or even a safety hazard.
Here at Blanket Insider, we’ve taken the guesswork out of the process. We’ve washed numerous electric blankets, consulted dozens of user manuals, and learned the best practices for keeping them safe and functional. You’re in the right place to learn exactly how to wash a heated blanket. Follow this guide to clean yours with confidence.
Quick Safety Checklist: Before You Begin
Your safety is the #1 priority. Before washing, confirm the following:
- Read the Care Label: Does it explicitly say “Machine Washable”? If not, you must hand wash or spot clean.
- Unplug Everything: The blanket must be disconnected from the wall outlet.
- Detach All Controls: The control module and any cords connected to it must be completely removed from the blanket itself. Never submerge electrical components.
- Inspect for Damage: Check for any frayed wires, cracks, or burn marks. If you find any, stop using the blanket immediately.
Special Considerations for Different Types of Heated Blankets
Not all heated blankets are the same. Here’s what to know based on your specific type:
Electric Blankets vs. Heating Pads
While similar, electric blankets are typically larger and may have removable controllers, making them more suitable for machine washing if the label allows. Heating pads usually have integrated controls and are often spot-clean only. Always check the manufacturer’s instructions for your specific device.
Seasonal Storage Tip: When putting your heated blanket away for warmer months, ensure it’s completely clean and dry. Store it loosely folded in a breathable cotton bag in a cool, dry place. Never store it tightly compressed, as this can stress the internal wiring.
Automatic Shut-Off vs. Manual Controls
Blankets with automatic shut-off features often have more complex wiring. Take extra care when washing these models. Blankets with simple manual controls might be more forgiving, but the same safety rules apply.
The Step-by-Step Washing Process
Once you’ve completed your safety check, you’re ready to proceed. We’ve broken down the process into clear, manageable steps.
1 Spot Clean First (If Possible)
For minor spills or stains, spot cleaning is always the safest option as it minimizes wear on the internal wiring. Mix a small amount of mild detergent with cool water. Use a soft cloth to gently blot the stain, then “rinse” by blotting with a clean, damp cloth. Let the area air dry completely.
2 Choose Your Washing Method
Based on your blanket’s care label, choose one of the two methods below. When in doubt, hand washing is the gentler and safer option.
Machine Washing (If Allowed)
- Use a large, front-loading washer. Top-loaders with agitators can snag and damage the wires.
- Wash the blanket alone to prevent tangling.
- Select a short, gentle cycle (e.g., “delicates”) with a cold or lukewarm water setting.
- Use a small amount of mild, bleach-free detergent.
- Allow the machine to run for only a few minutes for the wash and rinse cycles.
Hand Washing (Safest Method)
- Fill a clean bathtub with cool water and a capful of gentle detergent.
- Submerge the blanket and gently swish it for a few minutes. Let it soak for 15 minutes.
- Drain the soapy water and refill with clean, cool water to rinse.
- Gently press the water out of the blanket. Do not twist or wring it out, as this can break the internal wires.
- Repeat the rinse process until all soap is gone.
3 The Crucial Drying Stage
This is where most damage occurs. High heat is the enemy of a heated blanket.
- Air Drying (Recommended): The safest way to dry is to lay the blanket flat over a clean surface, several drying racks, or a clothesline (draped, not hung by clothespins). Flip it every few hours. It may take 24 hours to dry completely.
- Tumble Drying (Use Extreme Caution): If, and only if, the label allows, you may use a dryer. Set it to the absolute lowest heat setting or an “air fluff” (no heat) cycle. Check it every 20-30 minutes and remove it while it is still slightly damp to finish air drying.
4 Final Safety Inspection
Before plugging your blanket back in, perform one last check. Ensure the blanket and all connection points are 100% dry. Reattach the control module securely. Plug it in, turn it on to a low setting, and monitor it for a few minutes to ensure it’s heating evenly and correctly. If you notice any unusual smells or hot spots, unplug it and discontinue use immediately.
Troubleshooting Common Heated Blanket Problems
Even with proper care, issues can arise. Here are solutions to common problems:
Problem: Blanket Stops Working After Washing
Possible Cause & Solution: This usually indicates moisture trapped in the wiring or a loose connection. First, ensure the blanket is COMPLETELY dry—this may take an additional 24 hours in a warm, dry room. Check that the controller is firmly attached. If it still doesn’t work, the internal wiring may have been damaged during the wash, and the blanket should be replaced for safety.
Problem: Uneven Heating or Cold Spots
Possible Cause & Solution: This can occur if the blanket was wrung, twisted, or folded tightly while damp, damaging the heating elements. Unfortunately, this damage is often permanent. For safety, discontinue use of a blanket with uneven heating, as it can pose a fire risk.
Problem: Strange Smell When Turned On
Possible Cause & Solution: A burning smell indicates serious danger—unplug immediately and do not use. A musty smell suggests trapped moisture. Unplug the blanket and allow it to air out completely in a dry, well-ventilated area for several days. Never use a blanket that produces any unusual odors.
Essential Dos and Don’ts
Keep these simple rules in mind to ensure a long, safe life for your heated blanket.

Frequently Asked Questions
How often should I wash my heated blanket?
Unless visibly soiled, most heated blankets only need washing once or twice per season. Frequent washing increases wear on the electrical components. Using a removable, washable cover can help keep it clean between washes.
Can I wash an electric blanket with automatic shut-off?
Yes, but with extra caution. These blankets have more sensitive electronics. Always follow the manufacturer’s instructions precisely. Hand washing is often the recommended method for blankets with advanced safety features.
What’s the difference between washing a heated blanket and a regular blanket?
The key difference is the electrical wiring. Regular blankets can withstand more agitation and higher temperatures. Heated blankets require gentler cycles, cold water, and no-heat drying to protect the delicate heating elements from damage.
How long do heated blankets typically last with proper care?
With proper washing and storage, a quality heated blanket can last 5-10 years. However, if you notice any signs of wear, fraying wires, or inconsistent heating, it’s time to replace it for safety reasons.
Recommended Care Products
Using the right tools can make all the difference. Here are a few products perfect for safely caring for your heated blanket and other delicate items.

Important Safety Reminder
Heated blankets are electrical appliances. Improper care can create fire hazards or electrical shock risks. Always prioritize safety over convenience. If your blanket shows any signs of damage—frayed wires, discolored fabric, hot spots, or unusual smells—discontinue use immediately and replace it. Your safety and the safety of your home are more important than any blanket.
For those with specific health conditions or concerns about electric blanket safety, consider exploring alternatives like microwaveable heating pads or traditional blankets for warmth during colder months.
