Using Bleach on White Wool

By Dr. Laundry January 19, 2010

Q. I used Clorox® Regular-Bleach1 on a white wool item and it became a yellowish color. Is there anything that I can use to restore its original color?

A. Bad news. On the back label of all our liquid bleach products is a statement: “Avoid bleaching wool, silk, mohair, leather, Spandex and non-fast colors.”

Unfortunately, the yellowing is permanent and not reversible. The bleach reacts with the wool and changes the chemical composition. Wish I had better news.
