What causes yellow armpits? Does anyone know how to prevent yellow armpit stains?
I don’t know exactly what causes the yellow stains or how to prevent them but there is a product called YELLOW OUT. It’s made by Iron Out, Inc. and it’s found in the laundry supply aisle at most grocery stores. It works well on whites. It comes in a white plastic bottle with a yellow and blue label. Unfortunately, the stain will probably return after a few more wearings.
