Can you wash black and white together

Short answer: No, not if the white is to stay white. Black gives off colour in the first many washes, and even a small amount of colour turns white greyish over time. Sort the wash, and mix only once the black is older.

Black gives off colour for a long time

For the first ten to fifteen washes, a black fabric still gives off colour. You cannot see it in the machine, but it settles in the other laundry. So washing new black once and hoping the colour is gone is not enough. Count the washes and keep black pieces separate at first. That goes for a black bamboo slip too.

Greyish white cannot be fixed

A greyish tone in white fabric does not turn white again. The colour has settled in the fibres, and ordinary washing does not remove it. Prevention is therefore the only solution. If light bamboo socks for women are to stay light, wash them with other light laundry.

Old black is fine

After many washes, a black fabric gives off almost no colour. An old black piece can therefore run with light clothes without leaving a trace. The limit is not sharp, so take care with pieces that are still fairly new. If you need new tops, see the bamboo tops for women.

Sort into three piles

Divide the laundry into light, dark and new black. It takes a moment and is the simplest habit that protects the white. New black goes in its own machine until it no longer gives off colour. Then it can join the dark pieces. The system needs nothing more than an extra basket.

Light with light

Wash white with other light laundry. Even a small amount of colour can turn white greyish over time, and it happens gradually, so you do not notice until the difference is large. If in doubt, compare a white piece you have had a long time with a new one.

Test with a single cloth

If you are unsure whether a black piece still gives off colour, wash it together with an old white cloth and see whether the cloth takes on colour. If it does, wait before mixing. The method is simple and costs only one small load.

Do not save a machine

It is tempting to put everything together to save a load. But a greyish tone in light laundry cannot be removed again, and that costs more than the load you saved. Better one extra load than a white piece that never becomes properly white again.

The colour does not last forever

Black laundry gives off less and less the more often it has been washed. So you do not need to sort for life. After a while, the oldest black pieces can run with the rest. The figure of ten to fifteen washes is a guideline, not a guarantee, so watch how the white looks.

Frequently asked questions

Can you wash black and white together

No, not if the white is to stay white. Black gives off colour in the first many washes and turns white greyish, even if you cannot see it straight away.

How long does black give off colour

The first ten to fifteen washes. After that the release is so small that an old black piece can run with light clothes, but take care with newer pieces.

Can you get greyish white white again

Rarely. The colour has settled in the fibres, and ordinary washing does not remove it. Prevention is the only solution, so sort before you wash.
