- Clothesline or drying rack
Materials
- Mild laundry detergent
Easy Instructions: Washing Your Electric Blanket

Step 1: Preparing Your Electric Blanket for Washing
Gently shake the blanket to remove loose debris. Before placing the electric blanket in the washing machine, ensure all cords and controls are detached according to the manufacturer’s instructions.

Step 2: How to Load Your Electric Blanket into the Washer
In high-efficiency washing machines, load the blanket loosely. For standard top-loading machines with a center agitator, distribute the blanket evenly around the drum. To balance the load if necessary, add a few lightweight, non-lint-producing items like sheets.

Step 3: Choosing the Right Water Temperature and Detergent for Electric Blankets
Wash the blanket using cold or lukewarm water and a small amount of mild laundry detergent.
Warning
Do not use chlorine bleach or fabric softeners, as these products can damage the insulation of the blanket’s internal wiring.

Step 4: Selecting the Best Washer Cycle for Your Electric Blanket
- Select the gentle or delicate cycle, using the shortest wash duration available.
- If your washing machine allows, set the final spin speed to the lowest setting to minimize stress on the blanket’s internal wiring.

Step 5: Optimizing Wash Time – Short Agitation & Rinse for Electric Blankets
- Allow the machine to agitate for only two to three minutes. Then, if possible, manually advance the cycle to rinse.
- Remove the blanket promptly once the rinse cycle is finished.

Step 6: How to Safely Dry Your Electric Blanket
- Use a cool air, air-only, or very low heat setting on your clothes dryer.
- It is often recommended to partially dry the blanket in the dryer for a short period (e.g., 10-20 minutes), then remove it while still damp. Finish by air-drying it completely on a clothesline or drying rack. Excessive heat can damage the wire insulation or cause shrinkage.
- Ensure the dryer drum is large enough for the blanket to tumble freely. If not, consider using a large-capacity dryer at a laundromat, strictly using an air-dry or cool setting.

How Often Should You Wash an Electric Blanket?
The frequency of washing an electric blanket depends on its usage and whether it comes into direct contact with skin. Generally, wash it when visibly soiled, at the end of its season of use before storage, or as recommended by the manufacturer. Always handle it gently during cleaning to protect internal components.
Expert Tips: Best Practices for Washing Electric Blankets
- Address stains promptly. After unplugging the blanket, gently blot the stain. Apply a small amount of mild detergent to the spot, then carefully remove the detergent with a clean, damp cloth until rinsed.
- If your washing machine is too small for the blanket to fit loosely, hand-wash it. Use a bathtub or large basin with cold water and a minimal amount of mild detergent. Gently squeeze the soapy water through the blanket. Do not wring or twist. Rinse thoroughly with clean water.
- Never dry-clean electric blankets or heated mattress pads. The solvents used in dry cleaning can damage the insulation of the wires.
- Avoid using commercial dryers that operate at very high temperatures, as this heat can harm the internal wiring.
- Consider replacing electric blankets that are over 10 years old, or sooner if recommended by the manufacturer or if signs of wear appear. Older blankets may have an increased risk of malfunction.
- Do not iron an electric blanket. The heat from an iron can melt or damage the wire insulation. If wrinkled, hang the blanket, gently smooth it by hand, and allow gravity to reduce the wrinkles.
Proper Storage Guide for Your Electric Blanket
When not in use, such as during warmer months, electric blankets and heated mattress pads should be stored correctly. Use this checklist to ensure your blanket is properly stored and ready for use when needed.
- Disconnect controls from the blanket and unplug from the wall. Inspect the blanket for any damage such as exposed wires, scorched areas, rips, or tears. Assess if repairs are possible or if the blanket requires replacement.
- Before storing, ensure the blanket is clean and completely dry according to the washing instructions. Inspect controls and cords for any cracks, discoloration, or damage. If damage is found, the blanket or its components should be replaced.
- Once clean and thoroughly dry, roll the blanket loosely. Avoid making sharp folds or creases, which can damage the internal wires. Store in a dry, climate-controlled area, protected from insects and rodents.
- Store controls and cords unplugged from the blanket. Loosely coil the cords, ensuring they are not bent, pinched, or tightly wound. Place the blanket and its accessories together in a breathable storage bag or container to prevent dust accumulation.

Will machine washing ruin an electric blanket?
Most modern electric blankets are designed to be machine washable. Their heating elements are encased in protective, flame-retardant, and water-resistant insulation. However, gentle handling (e.g., no crushing or wringing) is crucial to keep the internal heating grid intact. Always check the care label, as some older or specific models may require hand-washing only.
-
Can I dry an electric blanket in the dryer?
Yes, typically an electric blanket can be partially dried in a dryer on a very low or no-heat setting for a short duration. However, it is generally recommended to finish by air-drying completely on a clothesline or drying rack. High heat from a dryer can damage the blanket’s wiring or insulation.
-
How do I hand-wash an electric blanket?
First, disconnect all power cords. Fill a bathtub or large basin with cold or lukewarm water and a small amount of mild laundry detergent. Submerge the blanket and let it soak for about 15 minutes. Gently agitate the water and squeeze it through the blanket for a few minutes. Avoid twisting or wringing. Drain the soapy water, refill with clean, cool water, and gently swish the blanket to rinse. Repeat rinsing if necessary until all detergent is removed.
-
Is it dangerous to use an electric blanket on pet beds?
It is generally safer to use heated beds specifically designed for pets rather than a standard electric blanket. Electric blankets intended for human use may become too hot for animals, and their cords may not be chew-resistant. Pet-specific heated beds are designed for appropriate temperatures and durability for animal use.
-
How do I know when to throw away an electric blanket?
Discard an electric blanket if you observe any signs of damage such as frayed or worn fabric, scorch marks, exposed wires, or damage to the cord, plug, or controller. It’s also advisable to replace electric blankets that are more than 10 years old, or as per the manufacturer’s lifespan recommendation, due to potential degradation of components over time.
