Colour and how often you wash

Short answer: Colour changes when you notice that something needs washing, not when it actually needs washing. Dark clothes get just as dirty as light ones, it simply shows later. That is why a regular routine is more reliable than looking for stains.

Dirt is there whatever the colour

Sweat and skin oils settle in the fabric every time you wear it, on black just as on white. You cannot see it, but it is there. This matters most for clothes worn close to the skin all day, such as a long sleeve top under a jumper. See long sleeve styles.

Dark tempts you to wait

Because stains do not show, dark clothes are often washed too rarely. They look clean, so you wear them one more day. But dirt builds up in the fibres whether you notice it or not. Underwear in particular should be washed after every wear, whatever the colour. See bamboo boxers.

Light shows more

Light clothes show sooner that they have been worn. A yellow edge at the collar or a grey tone at the cuffs tells you it is time. Light clothes do not get dirtier, they just show it more clearly. Treat it as a reminder that your dark clothes are probably at the same point.

Wash by wear, not by looks

A fixed routine is more reliable than your eyes. Decide how many times a piece is worn between washes, and stick to it. Underwear after every wear, a top next to the skin after one or two, and a sweatshirt worn over a layer after a few. See bamboo sweatshirt for men.

Smell is a better signal than stains

If you want to trust your senses, use your nose rather than your eyes. Odour comes from sweat and skin oils that have started to settle, and that happens just as fast on every colour. When a piece no longer smells fresh, it is time to wash it, even if it looks clean.

What happens if you wait

The longer sweat and skin oils stay in the fabric, the deeper they settle. They become harder to wash out, and an odour can linger even after washing. On light clothes this can leave yellow edges, and on dark clothes the fabric can look dull. Washing often is easier than rescuing a garment later.

Gentle washing handles frequent washing

If you wash more often, it pays to wash gently. Use a low temperature, a mild detergent and skip fabric softener. Turn dark clothes inside out so the colour lasts. That way your clothes can handle a regular routine without wearing out faster, and they keep their soft feel.

Air out between wears

Between washes, hang clothes up to air rather than leaving them in a pile. This helps most with tops and sweatshirts worn over another layer. Fresh air does not remove dirt, but it helps clothes stay fresh until the next wash comes round.

Frequently asked questions

Can you wash dark clothes less often

No. They get just as dirty as light clothes, you just notice later because stains do not show. Sweat and skin oils are there in the same way.

What should you wash by

By wear rather than by looks. A set number of wears between washes is more reliable than your eyes, and smell is a better sign than visible stains.

What happens if you wait too long

Sweat and skin oils settle into the fibres. They become harder to wash out and can leave an odour that lingers, even after several washes.
