Why is my underwear stained yellow?
Well, I've noticed it happening frequently lately. I usually wear light-colored clothes and I'm wondering if it's related to that.
It's possible that the yellow staining on your underwear is caused by frequent use of bleach or other lightening agents on your laundry. Another possible cause could be sweat or bodily fluids that are not completely removed during washing. Have you changed your laundry routine recently?
