From Wiki: Bluing, laundry blue, or washing blue is a household product used to improve the appearance of textiles, especially white fabrics. Used during laundering, it adds a trace of blue dye (often synthetic ultramarine, sometimes Prussian blue) to the fabric.
Also good for wasp stings.
WHITE COTTON SHIRTS GONE YELLOW
Have numerous high end white business shirts that are slowly turning a light yellow colour. They are all beautiful cotton and with a lot of life left, just noticing a very slight discolouration.
Any suggestions for returning them to white white.
Thanks
