Right now, some are soaking and some are out on the makeshift laundry line David strung up for me. It is sunny and 65 degrees in Dallas (yes, in JANUARY) so hopefully the "floating in the sun" methos will work wonders.
When I am out and about I will pick up some Oxy Clean or Restoration (if I can find it, or order it from http://www.englesideproducts.com/ ) and try some of the tips using that, such as the following found on EHow, if they still need it.
*Determine the durability of the antique linens. If you're worried that the linen won't withstand a solid soaking you might want to fold it neatly in a square and baste the edges with a color-fast thread.
*Fill a large tub with hot water and a mild soap. Restoration, Oxyclean or pure soap flakes are good options. Run the water until all the soap is dissolved. Soak the linens for several hours.
*Drain the tub. Check the linens. If stains are still present, repeat the soaking process again. After two soakings, if stains persist, try laundry detergent and bleach. Be sure to drain and refresh the water before adding a new kind of detergent, so as to avoid reactions.
*Refill the tub and add white vinegar. Let your stain-free linens soak up to 20 minutes.
*Drain tub again. Refill with fresh water and let linen soak for 15 minutes.
*Iron linens when they're still quite damp, but iron them only if you intend to use them right away. Iron them on high and keep the iron dry.
