Always read the care label before you wash anything; it is the manufacturer’s instruction for that specific garment and overrides any general advice, including this guide. Once you have checked it, the habits below describe what is commonly safe for cotton, wool, linen, silk, denim and synthetics.
How to read a care label
Care labels use symbols. A wash tub with a number usually shows the maximum water temperature. A triangle covers bleach, a square with a circle covers tumble drying, an iron symbol covers ironing and a circle covers dry cleaning. A cross through any symbol means do not do it. If the label is missing or has faded, wash gently in cool water and air dry, or test a hidden area first.
General habits that help every fabric
- Sort by colour and by weight so heavy items do not abrade delicate ones.
- Turn garments inside out to protect surfaces and prints.
- Close zips and fasten hooks to avoid snagging.
- Do not overload the machine; clothes need room to move and rinse.
- Wash less often when garments are not dirty. Airing a jumper often does the job.
- Treat stains early, and test a stain remover on a hidden seam.
Fabric by fabric
Cotton
Cotton is generally tough and tolerates regular washing, but it can shrink and fade, particularly in hot water and a hot dryer. Many labels recommend a warm or cool wash. Wash dark colours separately the first few times. Iron slightly damp for the best result.
Wool
Wool can felt and shrink with heat, agitation and friction. Many wool items can be hand washed in cool water with a wool-specific detergent, but some are labelled machine washable on a wool cycle and others dry clean only, so follow the label. Do not wring or twist; press water out with a towel and dry flat, away from direct heat. Fold knitwear rather than hanging it, to prevent stretching.
Linen
Linen softens with each wash and handles regular laundering well, though it creases and can shrink. A cool to warm wash and a gentle cycle suit most pieces. Many people like the natural crumpled look; to press it, iron while damp at a setting the label allows.
Silk
Silk is delicate. Many silk items are labelled dry clean only; others can be hand washed in cool water with a mild detergent made for delicates. Avoid wringing, hot water and sun-drying, which can fade it. Roll in a towel and dry in the shade.
Denim
Jeans do not need washing after every wear. When you do wash them, turn them inside out and use cool water to limit fading. Many people air dry to protect fit and fibres. Follow the label, especially for stretch denim, which can be sensitive to heat.
Polyester, nylon and other synthetics
Synthetics are usually durable and quick-drying but can hold odours and shed microfibres. A cool or warm wash and low heat in the dryer are common advice, though your label rules. Washing in a full load and using a filtering bag may reduce fibre loss.
| Fabric | Typical approach (check the label) | Avoid |
|---|---|---|
| Cotton | Warm or cool machine wash | Very hot washes on dark colours |
| Wool | Cool hand wash or wool cycle, dry flat | Heat, wringing, tumble drying |
| Linen | Gentle cool to warm wash | Harsh bleach, hot dryer |
| Silk | Dry clean or cool hand wash | Wringing, direct sun |
| Denim | Inside out, cool wash, air dry | Frequent hot washing |
| Synthetics | Cool or warm wash, low heat | High heat, which can damage fibres |
Drying and storing
Heat is the most common cause of shrinkage and damage, so air drying is the gentlest option for most items. Hang shirts by the shoulders on a rack, and lay knits flat. Store clothes clean and dry, because stains and body oils left on fabric can attract insects and discolour over time. This matters particularly when you swap wardrobes between seasons, a topic we cover in how to dress for each season.
Stains, odours and small repairs
Blot, do not rub, fresh stains. Rinse in cool water and treat before the item goes in the dryer, since heat can set a stain permanently. For odours, air items outside in the shade. Fix loose threads and small holes quickly. Sustainability starts with clothes that last, which is one reason we recommend it in our sustainable fashion basics.
When to call a professional
Take structured items such as tailored jackets, beaded or embellished pieces, and anything labelled dry clean only to a cleaner you trust. If a garment is valuable or sentimental, and you are unsure, it is better to ask first.

Pull out the five clothes you wear most and read each care label. Write the key instruction on a note and place it by your washing machine, then sort your next load accordingly. For more everyday help, see our fashion guides.
Frequently asked questions
What do I do if a garment has no care label?
Treat it cautiously: wash by hand or on a gentle cycle in cool water and air dry. Test any detergent or stain remover on a hidden area first.
How often should I wash jeans?
There is no fixed rule. Many people wash them after several wears, or when they are dirty or smell, and always follow the care label.
Can I put wool in the washing machine?
Only if the care label says it is machine washable, usually on a wool or delicate cycle. Otherwise hand wash in cool water or dry clean.
Does air drying really help clothes last longer?
Generally yes, because high dryer heat can shrink and weaken fibres. Check the label, since some items are fine in a low-heat dryer.
How do I stop colours from fading?
Wash dark and bright items inside out, in cool water, and separate them from lights. Avoid over-washing and strong sunlight when drying.
