How to Wash Bedding in a Washing Machine: A Complete Guide

Most machine-washable bedding can be cleaned at home by running a separate load, following the care label’s temperature, and drying on low heat.

A bloodstain on a pillowcase survives the wash cycle and comes out darker than it went in — that happens when the load was too full and the water too cool for the fabric. The label sewn into the hem is the first thing worth reading, because it sets every limit that follows. The steps below split into two jobs: sheets, which are easy, and comforters and pillows, which need space and patience.

The single biggest mistake is mixing bulky items into one load. Whirlpool’s laundry guidance says sheets belong in their own load, away from towels and comforters, and that matters more than detergent choice. Comforters go alone.

Read The Care Label Before Anything Else

The care label is the controlling instruction for washability and maximum water temperature, and no generic advice overrides it.

A washtub symbol means the item can be washed, and a number inside the tub shows the hottest temperature allowed — one dot or the number 30 means cool, three dots or higher means warm to hot. A tub with a hand in it means hand wash only; a tub with an X through it means no machine washing at all.

Some bedding, including certain wool, silk, and dry-clean-only duvets, carries that X. Those items go to a professional cleaner, and no washer setting fixes them. If the label is missing, treat a natural-fiber comforter as dry-clean-only rather than gambling on it.

How To Wash Sheets Without Tangling Them

Sheets wash on a sheets cycle or the normal/regular cycle in warm water, and they need room to move freely rather than a packed drum.

Whirlpool recommends loading sheets evenly around the agitator or drum so they don’t bunch into a rope and trap dirt in the middle. Add nothing else — towels shed lint onto sheets and tangle around them.

  • Pretreat stains first: a fabric-safe pre-wash stain remover on blood, sweat, or oil marks, applied before the load and given a few minutes to work.
  • Choose warm water for cotton, polyester, and linen; cool water for colors you’re worried about fading.
  • Use the normal amount of detergent, not extra. More suds don’t mean cleaner sheets.
  • Tumble dry on low. High heat is what shrinks cotton sheets over time.

If your washer is too small to let a queen set move, the load stays bunched and rinses poorly. A drum with enough capacity solves that before any detergent or cycle choice matters, and our roundup of washing machines built for bulky bedding loads covers which capacities actually handle a comforter.

Bedding Item Recommended Wash Cycle Water Temperature And Drying
Cotton, polyester, or linen sheets Sheets cycle, or normal/regular Warm water; tumble dry low
Down comforter or duvet Bedding cycle, washed separately Warm water, mild detergent; dry low with dryer balls
Pillows (down or fiberfill) Bedding cycle Cool or warm water, mild detergent
Delicate or specialty fabrics Follow the care label only Per label; some require hand washing
Dry-clean-only bedding No machine washing Professional cleaning

Washing Comforters, Duvets, And Pillows

Down comforters and pillows wash on the Bedding cycle with warm water and mild detergent, and bleach is never used on down.

Samsung’s bedding care guidance is specific here: wash these items separately, use a mild detergent, and expect that a large or heavily soiled comforter may need a second rinse cycle to flush out leftover soap. Residue left in down is what leaves a stiff, flat comforter after drying — a small extra rinse protects the fill.

Drying is where down bedding is won or lost. Use a large-capacity dryer on low heat, and add dryer balls or dryer rings to break up clumps as the feathers dry. A comforter pulled out while still damp inside will smell musty within a day, so expect two or three low-heat cycles rather than one long hot one. Never use bleach or fabric softener on down; both damage the feathers’ natural loft.

Pillows follow the same logic at a smaller scale — Bedding cycle, cool or warm water, mild detergent, and a low-heat dry with the same dryer balls to restore shape.

FAQs

Can I wash bedding with towels or other laundry?

No, keep them separate. Bulky items tangle together in the drum, which stops water and detergent from reaching the fabric evenly, and towels transfer lint onto sheets. Run sheets as one load, comforters as their own load.

Why does my comforter still smell after washing?

Damp down or fiberfill in the center is the usual cause. The outer fabric dries first while the inside stays wet, so run additional low-heat cycles with dryer balls until the comforter is dry all the way through.

Hot water does reduce germs, but the care label sets the real limit. Many fabrics shrink or fade above warm, so follow the label’s temperature instead of defaulting to the hottest setting your washer offers.
