Washing bamboo socks without them shrinking
Short answer: Bamboo socks shrink least when you wash them gently by the care label, at a low temperature and without high heat in the tumble dryer. Wash them inside out in a wash bag and let them dry on the line. It is heat and mechanical wear that are most often the cause.
Why socks shrink
Viscose from bamboo can shrink if it is exposed to high heat or heavy mechanical action, especially when it is wet. That applies to other fibres too, but viscose is a little more sensitive. So temperature and drying are what you should watch when you wash bamboo socks.
Start with the label
Read the care label in your socks, because it is always more important than general advice. The label shows temperature, spin and whether the socks can go in the tumble dryer. See bamboo socks for men and compare instructions if you want to know what is normal. Follow the label from the first wash.
Low temperature and a gentle programme
Choose a low temperature and a gentle programme if the label allows it. High heat in the water can make the fibres contract so the socks become too small. A short, cool wash is usually enough for everyday dirt. If the socks are very dirty, soak them first.
Wash bag and inside out
Turn the socks inside out and put them in a wash bag. That way the surface is less exposed to wear, and the small pieces do not vanish. Do not wash the socks together with heavy items with zips and velcro. Sort socks by colour so they stay nice for longer.
Detergent and fabric softener
Use a normal amount of mild detergent and do not overdose. Fabric softener can leave a film on the fibres, so many skip it, and some labels advise against it. If you are unsure, wash without and see whether the socks still feel soft. Soap residue can make them stiff.
Spin without wringing
Do not wring the socks, because wet viscose is weaker than dry and can lose its shape. Use a moderate spin or press the water out gently with your hands. Take the socks out of the machine at once and shake them lightly. Then they do not lie damp and creased in a heap.
Drying on the line or in the dryer
Drying on the line is the gentlest method. Hang the socks up in pairs and avoid direct sun and radiators. If the label allows a tumble dryer, use low heat and take them out while they are still slightly damp. See also all bamboo socks for men if you need more pairs.
If they have become too small anyway
If the socks have shrunk, you can gently pull them into shape while they are damp and lay them flat to dry. It does not always work, but it can help a little. Next time choose a lower temperature and hang them up. Also remember bamboo underpants for men in the same wash.
Frequently asked questions
Can bamboo socks go in the tumble dryer?
Only if the label says so. Then choose low heat and take the socks out while slightly damp. Line drying is the safest method.
What temperature should I wash bamboo socks at?
Follow the label. A low temperature is often gentlest, and you should avoid high heat, which can make the socks shrink.
What if the socks have shrunk?
Gently pull them into shape while they are damp and let them dry flat. Next time wash lower and avoid the dryer.
