Should socks be washed inside out

Short answer: Yes, if you want the colour to last and to avoid pilling. Turning socks inside out puts the worn surface on the inside, so the side that shows is protected in the machine. At the same time, the water reaches the side that was against your skin.

What turning them does

During a wash, clothes rub against each other and against the drum. When you turn the sock inside out, the friction hits the inside while the outside stays neat. This matters most for dark colours, where wear quickly shows as a grey haze or small bobbles. Black and navy socks for women keep their colour longer when washed inside out.

Cleaning gets better

Sweat and skin residue sit on the inside of the sock, because that side was against the foot all day. When you turn the sock, water and detergent reach the dirty layer directly. That is why socks for men and women come out cleaner at the same temperature, and you do not need to turn up the heat to get them fresh.

Pilling comes from friction

Pilling is small balls of fibre that have rubbed loose and tangled on the surface. They form where the fabric meets the most friction. When the sock is inside out in the machine, any pills form on the inside, where nobody sees them. The outside keeps its smooth surface, and the sock looks newer for longer.

The downside is sorting

Turning socks back and forth takes time, especially when there are many pairs in the basket. The easiest way is to turn them when you take them off in the evening. Then they are ready for the machine, and once they are dry you turn them back while you pair them. This works for every style in socks for men.

Wash with similar colours

Turning protects the outside, but it does not stop dye from transferring between different items. Wash dark socks separately from light ones. New socks in strong colours are best washed on their own the first few times. That keeps the white ones white and the black ones deep black through many washes.

Temperature and drying

40 degrees is enough for socks that have been worn for a day. Higher temperatures wear on the elastic in the cuff, whichever side faces out. Let the socks air dry on a rack instead of in the tumble dryer. That protects both fibres and elastic, and the socks keep their shape longer than if they are tumbled every time.

A habit that pays off

Washing socks inside out takes almost no time once it has become a habit. In return, the colour lasts longer, the surface stays smooth and the socks come out cleaner. It is one of the small things that let a good pair of socks be worn for a long time before it needs replacing.

Frequently asked questions

Does it apply to white socks too

Yes. Turning them helps against a grey tint, because dirt on the inside rinses out more easily and the outside wears less in the drum.

Should they dry inside out

It makes no difference to the result. Turn them back when they are dry, and do it while you pair them, so the whole job is done in one step.

Does it help against holes

Not directly. Holes come mostly from friction in the shoe and from toenails, not from the machine. Turning protects surface and colour but does not reinforce heel and toe.
