Wash a damask linen tablecloth by hand in a large sink or bathtub after each use by submerging the tablecloth in room-temperature water.
Add a small amount of mild, bleach-free detergent, and gently agitate the tablecloth.
Bleach white damask tablecloths with an oxygen bleach containing hydrogen peroxide.
Rinse the tablecloth by submerging it in clear, room-temperature water. Handle it gently so the delicate fibers are not damaged.
Rinse the tablecloth under clear, running water to remove any soap residue.
Drape the tablecloth over a tautly strung clothesline so it doesn't wrinkle. Don't use clothespins, because they leave creases in the fabric. Keep the tablecloth out of direct sunlight so it doesn't yellow.
Iron the tablecloth while it is damp for best results, using the linen setting on your iron. Iron dark-colored or embroidered Damask tablecloths on the wrong side only.
Fold the tablecloth carefully and store it in a dry, well-ventilated cabinet or on a shelf. Do not place anything on top of the tablecloth.
