Towels and bedding are the laundry that gets washed most and thought about least. They're also the loads where temperature, drying and detergent residue make the most visible difference — a towel that's gone stiff and stopped absorbing, a sheet that smells musty a day after washing — and all of it is fixable.
The common guidance is towels every three or four uses and sheets weekly, with pillowcases more often if you have oily skin or acne. A towel that dries fully between uses lasts longer between washes; one that stays damp in a bathroom is growing things. See how often to wash your clothes for the rest of the wardrobe.
Warm water, around 40 °C, cleans towels and sheets well in an ordinary week. Go to 60 °C when hygiene matters — after illness, for dish towels, for bedding used by someone with allergies — provided the label allows it; most cotton towels and sheets do. Cold works for lightly used items but doesn't dissolve body oils as well, and body oil is what builds up in sheets.
Towels need to be dried completely; a towel folded slightly damp smells within a day. A medium dryer setting is safest for both towels and sheets, and line drying works well for sheets in particular. Don't dry towels on high just to speed things up — high heat stiffens the loops.
A towel or sheet that smells sour after washing was either dried too slowly, left wet too long, or washed in a machine that itself needs cleaning. Rewash it hot with detergent and no softener, dry it fully and quickly, and run the machine's drum-clean cycle or an empty hot wash if the problem keeps returning. Leave the door open between washes so the drum dries.
Dark and brightly colored towels bleed generously for their first few washes; wash them alone or with darks until a bleed test comes back clean. White towels and sheets can be kept white with the methods in our whites and bleach guide.
The bigger items follow the same logic as sheets — they just fail differently. Check the label first: most synthetic-filled pillows and duvets are machine washable, while feather and down often need a gentler programme or a professional clean, and the label wins every time. If an item has to be crammed in to fit, it won't wash clean — the outside rinses while the core stays soapy — so a duvet that fills the drum on its own belongs in a laundrette's larger machine. Wash pillows together rather than alone so the drum stays balanced, and dry filled items completely, breaking up clumps of filling as they dry — damp filling left in clumps is where mildew starts. Waterproof mattress protectors are the exception: high heat can damage the membrane, so keep both the wash and the dryer low unless the label says otherwise.
Not all towels and sheets are cotton, and the differences change the rules. Linen sheets get softer with every wash but crease deeply if over-dried — take them out while slightly damp. Flannel sheds lint generously when new, so wash new flannel sheets on their own for the first few washes, exactly as you would dark towels. Microfiber towels are the strictest of all: never use fabric softener on them — it clogs the fibers that do the absorbing — and keep them away from high dryer heat, which can melt the pile flat. When the label is unclear, our fabric care guide covers each material in turn.
Should I wash new sheets before sleeping on them?
Yes — like new towels, they arrive coated in finishing agents that feel slick and can irritate skin. A normal wash removes them and leaves the sheets more breathable.
Why do my pillowcases turn yellow?
Body oils, sweat and hair products build up faster on pillowcases than anywhere else on the bed. Wash them more often than the rest of the set, at the warmest temperature the label allows, and treat yellowed whites with the methods in our stain removal guide before the marks set.
Can I use vinegar to soften stiff towels?
Try an extra plain-water rinse first — detergent residue is the usual cause, and rinsing fixes it without adding anything. If you do add white vinegar to a rinse, never combine it with chlorine bleach in the same load or the same machine: chlorine bleach must never be mixed with vinegar or ammonia. Test vinegar on a hidden corner of a colored towel first.
How do I stop sheets balling up in the dryer?
Button or zip duvet covers closed before washing so smaller items can't collect inside, shake everything out between the wash and the dryer, and don't overfill the drum. Dryer balls help keep the load tumbling instead of rolling into a knot.
Which cycle should I use for bedding?
A cotton cycle with a full spin suits most sheets and towels, and if your machine has a bedding or bulky programme, it exists for exactly these loads. Our guide to wash cycles explains what each one changes.
LaundryMax keeps towels and bedding in their own loads with their own temperature and cycle, alongside your clothes. See how it works.
