How does one wash a silk necktie?

To wash a silk necktie, first check the care label for any specific instructions. If it's safe to wash, fill a basin with cold water and a few drops of mild detergent. Submerge the tie, gently agitating the water without rubbing or twisting, then rinse thoroughly with cold water. Hang it to dry away from direct sunlight, and avoid using heat to prevent damage.
