How to Clean an Electric Blanket: the Ultimate Complete Safety Guide
Machine washing is completely safe if you limit physical friction. Use a front-loading washer or a high-efficiency top-loader without an agitator column. Set the machine to cold or lukewarm water, never exceeding 105°F (40°C). Add a modest dose of mild laundry detergent. Heavy-duty detergents containing bleaches, enzymes, or industrial brightening agents deteriorate the polymer wire jackets over time.
Submerge the blanket and initiate a short pre-soak cycle of roughly 15 minutes to loosen dust mites and body oils naturally. Follow this with a gentle cycle wash lasting no longer than 2 to 5 minutes. That brief window cleans the fleece without subjecting the internal grid to repeated centrifugal whipping. Cancel the extended spin cycle; set the machine to a single, low-rpm spin simply to evacuate standing water.
If your washing machine features a central post agitator, resort to the hand wash technique. Fill a clean bathtub with cool water and a tablespoon of liquid detergent. Submerge the blanket gently, pressing the fabric down with your palms for several minutes without wringing or scrubbing. Drain the tub, refill it with clean rinse water, and press the soapy water out against the porcelain floor of the tub. Never twist the blanket to wring it out.
