Please do not use a chlorine bleach such as Clorox! If you have linen, bleaching puts tiny holes in the linen. Clorox also weakens the fibers in cottons as well. I have washed church linens for years and have had to discard expensive linens damaged by using Clorox. We use Biz or Oxy Clean or Linen Wash (usually sold in stores where antique linens are sold.) You can also use lemon juice. Soak them in Biz or Oxy Clean in a plastic bucket for 24 hours. You may soak again. Rinse and rinse again. I lay them flat to dry. Some lay them on the grass in the sun to dry, but I have cats and birds and a shady yard. I repeat...DO NOT use bleach!
Martha Pullen who teaches heirloom sewing and collects antique garments uses Biz.
