If you want to wash your bedding sustainably, it usually comes down to three things: do not wash hotter than necessary, load your washing machine wisely and use the tumble dryer as little as possible. For normal use, washing once a week at 40°C is often enough. Only in cases of illness, heavy sweating or visible soiling is 60°C sometimes the better choice. That way your bed stays fresh, the fabric feels comfortable and your bedding often lasts longer.
Start with the 3 choices that make the biggest difference
The first choice is how often you wash. For duvet covers, fitted sheets and pillowcases, one wash a week is a good and practical guideline for most people. During warmer periods, if you sweat a lot, after illness or if pets sleep on the bed, washing more often can make sense. Waiting longer may sound more economical, but if sweat, skin oils and dust build up too much, it actually becomes harder to get everything clean in the end. You can find more practical tips in How to Keep Your Bedding Fresh.
The second choice is the temperature. In many cases, 40°C is enough for bedding. Modern detergents usually work perfectly well at this temperature and it is gentler on fibres than routinely washing at 60°C. That helps keep your bedding soft for longer. Whether your bedding is cotton, Tencel or microfibre, always check the care label before washing at a higher temperature.

The third choice is the programme. A longer eco programme or normal cotton programme at 40°C is often smarter than a short, hot cycle. The biggest part of the energy used for washing usually goes into heating the water. So washing at a lower temperature often saves more than people think, while a longer programme can still get things thoroughly clean.
- Choose 60°C mainly in cases of illness, heavy sweating or visible soiling, if the care label allows it.
- Wash new sets separately the first time, or with similar colours.
- Washing hotter is not automatically better, but it is often harsher on the fabric.
Make your laundry routine smarter without extra effort
A sustainable wash is not only about temperature. Fill the drum well, but do not stuff it completely full. Bedding needs room to move around, otherwise dirt rinses out less effectively and creases or detergent residue are more likely to be left behind. A drum that is about three quarters full is often a good guideline.
Also do not use more detergent than necessary. The right dosage cleans better than too much detergent, and helps prevent your bedding from feeling stiff or heavy. For white bedding, a suitable detergent for whites is often useful. For coloured sets, a mild colour detergent helps keep the shades looking better for longer. If you want less packaging waste, choose refill packs, concentrated detergent or cardboard packaging wherever possible.
It is usually better to skip fabric softener. It often leaves a coating on the fibres, which means bedding breathes less well and absorbs moisture less easily. Especially with soft, comfortable materials, you want to keep that fresh, airy feel. A small splash of white vinegar in the fabric softener drawer can help with detergent and limescale residue. The smell normally disappears during the wash. You can read more about materials and certifications at sustainable bedding.
If you have stains or want to make white bedding look fresher again, treat the area first and only then wash it. Do not put it in the tumble dryer before the stain is out, because heat can actually set it. Also run your washing machine itself on a hot maintenance cycle from time to time, following the manual, so residue and musty smells are less likely to build up.
Drying with less wear and less energy
Air drying is usually the gentlest choice for both your bedding and your energy use. Give your duvet cover and fitted sheet a good shake straight after washing and hang everything with plenty of space around it. That helps it dry faster and reduces creasing. Drying outside often feels extra fresh, but drying indoors works perfectly well too if the room is well ventilated.
If you do use a tumble dryer, choose a low temperature and take your bedding out when it is just short of fully dry. Overdrying often makes fabrics stiffer and causes more wear to the fibres. That soft, inviting feel you want to climb into at night usually stays nicer if you dry it a little more gently.
Do not forget your pillows, duvet and mattress protector
Washing only your duvet cover is not always enough. Pillowcases and fitted sheets usually go into the wash weekly, but pillow protectors, mattress protectors and mattress covers also deserve attention. Many of these layers can, depending on the label, be washed every few months. That helps keep your bed fresh for longer.
Pillows and duvets need a little more care. Some can go in the machine, others need professional cleaning or cannot be washed at all. So always check the label carefully. One thing that almost always helps is airing them out regularly. You do not wash a mattress itself, but airing it, vacuuming it and washing the protector regularly does make a difference. Good care is often the simplest way to enjoy your bedding for longer. If you are ready for a new set, take a look at our organic cotton bedding.
Frequently asked questions about washing bedding sustainably
What is the best way to wash bedding?
The best approach is usually to wash once a week, follow the care label, choose 40°C for normal use, pick a suitable programme and do not overload the drum. Use enough detergent, but not too much, and preferably skip fabric softener.
Is 40°C enough for bedding?
Yes, in many cases it is. For normally used bedding, 40°C is often enough, especially with a good detergent and a programme that runs long enough. Only in cases of illness, heavy soiling or a lot of sweating can 60°C be a better choice, if the material can handle it.
What is the best wash programme for bedding?
A longer eco programme or normal cotton programme often works best. It combines enough wash time with lower energy use than washing unnecessarily hot. For delicate fabrics or smooth materials, a gentler programme may be better. The care label should always guide you.
How do I get my bedding bright white again?
Treat stains first, measure your detergent properly and use a suitable detergent for whites for white bedding. If the label allows it, an oxygen bleach can help with dullness. Only dry it once you can see the discolouration is really gone, otherwise heat can set it.
