What are these marks?
This white polo shirt had some light yellow staining along the fold of the collar and inside the placket, I tried every technique for removing similar stains that I usually have success with but it was to no avail..
I reluctantly decided to use a stain removal spray that had chlorine based bleach despite the fact that the shirt has navy detailing, the details are fine, however the yellow marks have turned a bright vivid red/pink. I assume the red of the French flag plays no part in this?
What are these stains and how do you remove them? Any help would be greatly appreciated
