White bamboo socks and how to keep them white

Short answer: White socks go grey from dirt that does not come off at too low a temperature, and from colour from other laundry. The material is not to blame.

The temperature has to be high enough

Grease and dirt from feet do not release properly at 30 degrees. Wash white socks at 40 degrees and occasionally at 60. See all bamboo socks for women.

Wash them separately

Even a single dark sock gives off enough colour to turn a whole machine greyish over time. White socks should be washed with white.

Bleach is not the answer

Chlorine bleach makes viscose fibres brittle and the socks break down faster. An oxygen based stain remover is gentler. See washing and care.

Keep them out of the dryer

Heat sets discolouration so it cannot be washed out later. Hang white socks to dry. See bamboo socks for women.
