Hang your satin tablecloth from a tall towel rack or door hook in your bathroom. Ensure that the lower portion of the tablecloth does not bunch on the ground.
Close your bathroom door and windows. Run a hot bath and allow the tub to fill completely. The water should be hot enough to emit visible, billowing steam.
Allow the tablecloth to hang in your steam-filled bathroom for 15 to 20 minutes. The humidity will release wrinkles and creases from the satin naturally.
Drape the tablecloth over your table immediately after this treatment. If you will be storing your tablecloth, hang it from a broad clothes hanger or roll it up gently.
