Jennifer, I hope you can help me. I have beautiful tambour curtains. They are 70% polyester, 30% cotton. The sun has caused some yellowing. Is there anything I can use to whiten them when I wash them? They are in excellent condition, have been washed numerous times. Not sure how to whiten and brighten them. Any ideas? Thanks in advance for any help you can offer. Susie

Dear Susie, A quick search on Askjeeves.com turned up this instruction to whiten white polyester:
Mix one cup Cascade and one gallon warm water in a plastic bucket. Soak the clothes in this mixture overnight, and then run them through the washing machine. Cascade removes the gray due to detergent residue build-up on white polyester. Try this and see what happens!
Jennifer
