Most clothes are washed more often than they need to be, and washing is the main thing that wears them out. Agitation, heat and detergent do more cumulative damage than wearing does — colour loss, pilling, thinning and dead elastic are all wash effects, not wear effects.
The rule is simple: wash things when they are dirty, not on a schedule.
By garment
| Garment | Wash | Dry | Notes |
|---|---|---|---|
| Underwear and socks | Every wear | Any method | No exceptions. Against the skin, always. |
| T-shirts and tops worn next to skin | Every 1–2 wears | Line or low tumble | Every wear in hot weather or if worn without a layer. |
| Bras | Every 2–3 wears | Flat, never tumbled | Rotate between three so elastic gets a rest day. |
| Jeans | Every ~10 wears | Line dry inside out | Cold wash, inside out. Denim degrades from washing, not wearing. |
| Trousers and chinos | Every 3–5 wears | Line or low tumble | Spot-clean between washes. |
| Wool jumpers | Every 5–10 wears | Flat, out of sunlight | Air overnight instead. Wool resists odour naturally. |
| Blazers and tailoring | Twice a season | Hang, do not tumble | Brush and steam between cleans. Dry cleaning is harsh. |
| Coats | Once a season | Per label | At the end of the season, before storage. |
| Activewear | Every wear | Line dry | Synthetics hold bacteria. Do not use fabric softener — it clogs the fibres. |
| Pyjamas | Every 3–4 wears | Any method | More often in hot weather or if you shower in the morning rather than at night. |
| Towels | Every 3–4 uses | Hot tumble occasionally | Must dry fully between uses or they sour. |
| Bed sheets | Weekly | Any method | Fortnightly at an absolute minimum. |
The principle behind the table
Two questions decide it: does it touch skin, and does it hold odour.
Anything worn directly against skin picks up sweat and oils every wear and needs washing on that basis. Outer layers — jumpers, blazers, coats, jeans — are separated from your skin by something else, and mostly need washing only when they are actually dirty.
What to do instead of washing
Most of the time something does not feel fresh, it is not dirty. Three interventions cover nearly all of it.
Before reaching for the machine
- Air it. Overnight on a hanger near an open window handles most wool and outerwear.
- Spot-clean marks with cold water and a little detergent on a cloth, working inward from the edge.
- Steam it. Steam kills most odour-causing bacteria and drops creases at the same time.
- Brush tailoring with a clothes brush — it removes surface dust that otherwise sets in.
- Freeze nothing. Freezing does not kill odour bacteria; this one is a myth.
Washing better when you do wash
Settings that extend garment life
- Cold, 30°C or below, for almost everything. Modern detergents are formulated for it.
- Turn things inside out — abrasion happens on the outside face.
- Fill the drum properly. Under-filling causes more agitation damage, over-filling washes badly.
- Use less detergent than the box says. Residue stiffens fabric and holds odour.
- Zip zips and fasten hooks before washing, so they do not snag everything else.
- Mesh bags for anything delicate, knitted or with straps.
- Line dry where you can. Tumble drying is the single harshest thing you do to a garment.
