How to Wash Sheets and Bedding the Right Way
Updated August 2026
The short answer
Sheets collect what you leave behind nightly (sweat, body oils, and skin), which is why they need washing weekly. Check the care label first: many cotton sheets tolerate warm or hot water well, but the temperature a specific sheet set can actually handle depends on its exact fabric, finish, and construction, not just the material name. A normal detergent dose and a full cycle clean effectively at whatever temperature your label allows, including cooler settings when that's what it recommends. Wash sheets as their own load: they need room to move, and they tangle everything else into a knotted mass. Skip fabric softener: it coats fibers, reduces breathability, and builds up into that not-quite-clean smell. Dry fully and completely. Slightly-damp sheets folded into a closet are the origin story of musty linen.
Before you start
Check the care label first — it's specific to your exact sheets, not just the general fabric type. As a general pattern, many cotton and percale sheets tolerate warm or hot water, sateen often does better warm, linen tends to prefer warm water and lower dryer heat, and bamboo or lyocell blends usually want cool water and gentle handling — treat these as starting points to check against your label, not guarantees.
Pillowcases work harder than anything on the bed (face oils, hair product, drool) and benefit from twice-weekly rotation if breakouts or oily hair are in the picture.
Treat stains before the wash: blood gets cold water first (it's the one bedding stain where the warm-wash rule inverts), and body-oil yellowing gets an oxygen bleach soak.
Washing sheets by material
Check your care label first — the temperature a specific sheet set can handle depends on its exact fabric, finish, and construction, not just the material name. As a general pattern: many cotton and percale sheets tolerate warm or hot water, sateen and blends often do better warm, linen tends to prefer warm water and lower dryer heat, and bamboo or lyocell blends usually want cool water and gentle handling. A cooler wash with a suitable detergent dose and a full cycle still cleans effectively — going hot is not required. Always check your care label; it overrides this general guidance.
Flannel sheets are a separate case: wash warm, not hot, and dry on medium-low rather than high. The brushed nap that makes flannel soft is more prone to pilling and shrinking under aggressive heat than a tighter weave like percale. As always, check the care label first — this is a general guideline, not a universal rule.
Steps
- 1Strip the bed and shake sheets out: crumbs and debris off before the drum, and untwist everything.
- 2Wash sheets as their own load, warm to hot per the care label, normal detergent dose.
- 3Add oxygen bleach to white sheets every few washes to hold the brightness without chlorine damage.
- 4Run an extra rinse if your machine offers it: sheets hold detergent residue in their folds.
- 5Dry thoroughly on medium, with wool dryer balls or a couple of clean tennis balls to keep them from balling up around themselves. Check the folds: fully dry means fully dry.
- 6Line-dry in sun when practical: free brightening and that specific clean-sheet smell.
- 7Rotate two or three sheet sets so washing day never becomes make-the-bed-at-midnight day.
What not to do
- Do not wash sheets with towels: lint transfer, tangling, and uneven drying, all in one load.
- Do not use fabric softener on sheets; it coats the fibers and traps the very oils you're washing out.
- Do not fold or store sheets even slightly damp.
- Do not wash blood stains in hot water; cold first, treat, then wash normally.
- Do not stretch the schedule past two weeks and expect the yellowing to wait for you.
Frequently asked questions
What temperature should sheets be washed at?
Check your care label first — the safe temperature depends on the specific sheet's fabric, finish, and construction, not just the material name. Many cotton and percale sheets tolerate warm or hot water, while sateen and blends often do better warm. A cooler wash still cleans effectively with a suitable detergent dose and a full cycle; going hot isn't required.
Can I wash sheets with towels or clothes?
Better not to. Towels shed lint onto sheets and out-abrade them; clothes tangle into the sheets and rinse unevenly inside them. Sheets washed alone clean better, rinse better, and dry evenly, and one bed's set plus pillowcases is a properly-sized load anyway.
Why do my sheets smell musty even after washing?
Almost always incomplete drying (folds hold damp longer than the surface suggests) or storage in a humid closet. Dry until the folds are truly dry, store only bone-dry linen, and if the smell persists on clean sheets, check the closet and the washer, in that order.
How do I keep white sheets from going dull?
Wash them hot enough (per label), skip fabric softener entirely, add oxygen bleach every few washes, and line-dry in sun when you can. Dullness is body oil plus residue accumulating; the routine above removes it faster than it builds.
Can I wash sheets and a comforter together?
No — wash them separately. A comforter needs more room to move than sheets do, and often a different cycle. See our guide to washing a comforter for comforter-specific care.
