Blue stains on white laundry

By Dr. Laundry November 5, 2008

Q. I have some really bad blue stains on almost all of my white laundry. I have added bleach to my laundry load, and it doesn’t seem to help. I have used the Clorox® Bleach Pen Gel and that doesn’t seem to get the blue out either. Do you have any ideas on how I can fix this?

A. Usually these types of stains are from dye transfer from a colored item that got mixed into the load by accident. However, all of your attempts to remove them with bleach suggest that these may not be dye transfer. Washing and pre-treating should have removed the blue dye. Another possibility is that this is from some other source, like fabric softener, which you would treat by rubbing the stains with bar soap and then rewashing.
