How to wash blankets

Typical machine settings

The table shows a lightweight cotton blanket. Fleece: cold only, no softener. Weighted: check the weight limit first — many are laundromat or spot-clean jobs. Comforters: delicate cycle, and only if the machine fits it loosely.

These settings match what our laundry checker uses. The garment's own care label always wins.

What blankets can usually be washed with

• Nothing, ideally — a blanket is its own load, both for cleaning and for machine balance.
• A second small throw of similar color and fabric, if the drum is big enough to keep everything loose.

What to keep separate

• Clothes — blankets wrap around smaller items, which then neither wash nor rinse properly.
• Towels — with fleece especially: towel lint plus fleece static is a fuzz disaster.
• Anything with zippers or Velcro — open-weave and knitted blankets snag on hardware.

Color considerations

• New saturated blankets bleed in their first washes — alone, always, the first time.
• Dark fleece shows every speck of light lint — one more reason fleece washes solo.
• Sun-fading is real for line-dried dark blankets; dry them in shade or inside out.

Fabric considerations

• Cotton throws and cellular blankets: the easy case — warm or cold, normal or delicate, low tumble.
• Fleece and sherpa: cold wash, no fabric softener (it mats the pile), low or no heat — and expect heavy lint shedding when new.
• Weighted blankets: check the blanket's weight against your washer's capacity BEFORE washing; many 15-20 lb blankets exceed home machines wet. Glass-bead and pellet fills differ — the label decides everything here.
• Comforters and duvet inserts: if it doesn't fit in the drum with room to move, take it to a laundromat's oversized machine. Down must be dried completely (low heat, dryer balls, patience) or it clumps and mildews.
• Wool blankets: wool rules — cold, wool-cycle or hand wash, never the dryer, dry flat.

Drying

• Low heat and extra time is the blanket formula; high heat shrinks cotton and melts fleece pile.
• Down and thick fills: dry until genuinely dry inside — stop-and-feel checks beat trusting the timer; a clumpy, cool center means keep going.
• Line drying works for everything except heavy fills that stretch wet (knits) — those dry flat.
• Re-fluff comforters with clean tennis balls or dryer balls.

Common mistakes

• Adding a blanket "on top of" a clothes load — the wrap-around problem ruins both.
• Washing a weighted blanket without checking the machine's capacity — burned-out bearings are a real repair bill.
• Softener on fleece — permanent matting of the pile.
• Putting a comforter away slightly damp — mildew inside the fill, and the smell never fully leaves.
• Dry-clean-only comforters into the machine — the fill shifts and clumps; the label means it.

When the usual advice changes

• Baby blankets follow baby-clothes rules: gentle fragrance-free detergent, no softener. See washing baby clothes.
• Electric blankets have their own strict label procedure — controller off and detached, specific cycles; never assume, always read it.
• Heirloom quilts and anything hand-stitched: hand wash or professional cleaning; a machine cycle can be the end of them.
