The best way to preserve your lace is to wash your socks by hand. Use cold or lukewarm water and a mild detergent specially formulated for delicate fabrics. Rub gently to clean. Avoid tumble-drying, as heat can damage delicate fibers. Lay your socks flat on a clean towel to air-dry. Don't hang them up, as this can stretch and distort the lace. Be careful not to rub your lace socks against rough or abrasive surfaces, which could damage them.
