Many people ask themselves the same question: How often should you really wash your clothes? While some throw their T-shirt into the washing machine after every wear, others simply let the shirt air out and wear it a few more times. But what actually makes sense?
Washing too often puts a strain on textiles, the environment, and your wallet. Washing too rarely, on the other hand, can cause hygiene problems. This laundry guide for everyday textiles shows how often clothes and household fabrics should be washed according to experts.
Why you shouldn't wash clothes more often than necessary
Every wash cycle has consequences:
- Textiles wear out faster
- Colors fade
- Energy and water are consumed
- Microfibers are released into the environment
Many garments need to be washed much less frequently than is often assumed.
How often should you wash clothes?
T-shirts and tops
Recommendation: After 1–2 wears. T-shirts have direct contact with the skin and absorb sweat; sometimes an odor can develop, especially in the armpits or under the chest. Therefore, always do the 'smell test'—if it smells like sweat, put it in the washing machine.
Wash sooner if:
- you are sweating heavily
- Sports
- high summer temperatures
Shirts and blouses
Recommendation: After 1–2 wears
Collars and armpit areas in particular collect sweat and skin oils and sometimes turn brownish. Deodorants also sometimes leave traces (especially on white textiles!).
Underwear
Recommendation: After every wear
Underwear should always be washed after a single wear for hygienic reasons; there is no debate about that!
Socks
Recommendation: After every wear
Even if they look clean, moisture and bacteria accumulate quickly; always put them in the laundry basket after wearing.
Pajamas
Recommendation: Every 3–4 nights
Anyone who sweats heavily at night should change them more often.
Sweater
Recommendation: After 4–6 wears
If a T-shirt is worn underneath, sweaters often stay fresh for a long time. Frequent airing out in between is sufficient.
Jeans
Recommendation: After about 5–10 wears
Jeans need to be washed surprisingly rarely.
Advantages of infrequent washing:
- longer durability
- better fit
- less color loss
Small stains can often be removed locally.
Jackets
Recommendation: 1–2 times per season
Except in case of heavy soiling or if the jacket was worn during sports, then you should clean it in between.
How often should you wash home textiles?
Bed linen
Recommendation: Every 1–2 weeks
Change more frequently if:
- allergies
- you are sweating heavily
- pets in bed
Towels
Recommendation: After 3–4 uses
Damp towels offer ideal conditions for bacteria.
This always makes me think of the scene in 'New Girl' when Nick says he never washes his towel because he's so clean after showering, so why wash the towel?
Dish towels
Recommendation: Every 2–3 days
Change immediately, especially after contact with raw meat or fish.
Blankets and throws
Recommendation: Every 2–3 months
More often depending on usage.
Drapes
Recommendation: 1–2 times per year
They collect dust, pollen, and odors. My mom always washed the curtains (and the windows too!) at the beginning of spring and in the autumn.
When clothes stay fresh even without washing
Not every garment needs to go straight into the washing machine.
Often, the following is sufficient:
- airing out on the balcony
- treating stains specifically
- brushing off dust and lint
- proper storage
This protects fibers and saves resources. In the past, there was a 'valet stand' where you could hang your worn clothes if you didn't want to put them in the laundry yet. But a normal chair works too.
The right washing temperature
Many garments are washed unnecessarily hot. In almost all garments, you can find a small instruction on how hot you are allowed to wash it; usually, it only says 30° C.
For most textiles, the following is sufficient:
- 30 °C for clothes that should be treated gently
- 40 °C for normal clothes
- 60 °C for towels and bed linen, but also in case of illness or special hygiene requirements
I almost always wash 'normal' clothes at 40°C; I always wash bed linen, dish towels, and towels at 60°C. For delicate garments, I only run them on the hand-wash program and at a maximum of 30°C.
Common washing mistakes
Too much detergent
More detergent does not automatically mean cleaner laundry.
Overloaded washing machine
The laundry needs space so that water and detergent can work.
Washing too often
Many garments suffer more from the washing machine than from being worn.
FAQ: How often to wash clothes?
How often should you wash jeans?

Do you have to wash a sweater after wearing it once?
No, usually 4–6 wears are sufficient.
How often to change bed linen?
Normally every 1–2 weeks.
Conclusion: Less washing is often better
Anyone who knows how often clothes should really be washed not only saves time and energy but also extends the lifespan of their favorite pieces. Many textiles need to go into the washing machine much less often than thought.
The best rule is: Do not wash by habit, but by actual need; here, the 'smell test' is a very good method to find out if the garment is still wearable. Washing less protects clothes, the environment, and the household budget equally.
