Preventing yellow bleach stains
I put straight Clorox® Regular Bleach2 on white jeans and now I have a yellow stain. How do I remove the bleach stain?
No matter what you are using bleach for, it should always be diluted and never used directly on a surface or fabric. Unfortunately you have first-hand experience with why we never recommend treating fabric with undiluted bleach. I wish I had better news, but instead of the yellow being a “stain” that can be removed, it is a permanent shift in the color of the white fabric (sort of the reverse of when undiluted bleach leaves a light spot on a colored item) and cannot be reversed.
Next time, be sure to wash the fabric in your washer with detergent and 3/4 cup bleach. You can also try soaking in a solution of ¼ cup Clorox® Regular Bleach2 added to 1 gallon cool water for up to 5 minutes, then rinse the slacks thoroughly. Air dry and check for success
