You can safely clean a heated blanket, but you must follow the care label and avoid harsh heat or wringing so you don’t damage the wiring or create a fire risk.

Quick Scoop

  • Always unplug and remove the controller/cord before cleaning.
  • Check the care label first; many modern heated blankets are machine-washable on a gentle cycle with cold or warm water and mild detergent.
  • Never use bleach, never wring or twist, and avoid high heat in the dryer.
  • When in doubt, hand wash gently and lay flat to dry.

Step-by-step: Machine washing

If your care label says the blanket is machine-washable:

  1. Unplug and detach
    • Unplug the blanket and disconnect the controller and any cords completely.
 * Check for visible damage to the fabric or wiring; do not wash or use if you see exposed wires or burns.
  1. Prep and pretreat
    • Smooth the blanket out and loosely fold or roll it so it fits without cramming in the washer (ideally a large-capacity drum).
 * Spot-treat stains with a small amount of mild liquid detergent and a soft cloth or soft brush; dab rather than scrub hard.
  1. Wash settings
    • Use a gentle or delicate cycle, cold or lukewarm water, and a small amount of mild detergent.
 * Skip bleach and fabric softener, as they can damage fibers and possibly affect the insulation around the wiring.
  1. Spin and remove
    • Allow a short or normal spin, then immediately remove the blanket so it doesn’t sit bunched up and saturated.

Step-by-step: Hand washing

Hand washing is safer for older or more delicate heated blankets (as long as the label allows immersion):

  1. Prep the blanket
    • Unplug and remove the controller and cords.
 * Pretreat stains with diluted mild detergent and a soft cloth, then gently blot.
  1. Wash in tub or sink
    • Fill a tub or large sink with cool to warm water and mix in a small amount of mild detergent.
 * Submerge the blanket (wiring part only, no controller) and gently agitate with your hands—no twisting or wringing.
  1. Rinse and press
    • Drain, refill with clean water, and swish until no suds remain, repeating as needed.
 * Press water out by gently pressing sections of the blanket against the side of the tub or between your hands; do not wring.

Drying safely

Drying is where many heated blankets are ruined, so go slowly:

  • Initial moisture removal
    • After washing, gently press out extra water; rolling the blanket in a large dry towel and pressing helps absorb moisture.
  • Machine drying (only if label allows)
    • Use low heat or air-fluff and dry for a short time (often about 10–15 minutes) just to remove most dampness.
* Remove promptly, then lay flat on a drying rack or clean surface to finish air-drying completely.
  • Air drying
    • Lay the blanket flat on a bed, rack, or clean surface; smooth it to distribute internal wiring evenly.
* Avoid hanging from one edge—weight from the water can pull and stress the internal wires.
  • Before plugging back in
    • Ensure the blanket is completely dry throughout, including seams and connector port areas.
* Reattach the controller, check for any unusual bumps, hot spots, or damage; stop using and contact the manufacturer if anything seems off.

Quick FAQ and extra tips

  • How often to wash?
    • Many manufacturers suggest a full wash once or twice per season, with spot-cleaning as needed, depending on use and spills.
  • Can every heated blanket be washed?
    • Most modern electric blankets are made to be washed, but some older or specialty models may be “surface clean only,” so the label always wins.
  • What about quick spot-cleaning?
    • For small spills, unplug, remove the controller, dab with a cloth dipped in mild soapy water, then wipe with a clean damp cloth and let air-dry fully before use.
