If the socks have a label that specifically says "hand wash," it is best to follow the care instructions provided. Washing them in the washing machine, especially with other clothes, might risk damaging the socks or reducing their lifespan. "Hand wash" instructions typically indicate that the item is delicate or made of materials that require gentler handling.
Here are a few reasons why you should be cautious:
Agitation: Washing machines can be rough on delicate items, and the agitator or drum's movement may cause excessive friction and lead to damage.
Temperature control: Hand wash instructions often imply that the item should be washed in cool or lukewarm water, as hot water could be too harsh. Washing machines might not have the necessary temperature control for such items.
Detergents: Some detergents used in washing machines can be too harsh for delicate fabrics, potentially causing discoloration or fabric weakening.
Other clothing: Washing the socks with other clothes may increase the risk of tangling, stretching, or snagging, especially if the other clothes have zippers or hooks.
If you really need to machine wash the socks and they seem relatively sturdy, you can try using a delicate or gentle cycle with cold water. However, it's essential to recognize that there's still a risk involved. If you want to extend the life of your "hand wash" labeled socks, it's better to wash them by hand following the care instructions.
