Mrs Stewart's Liquid Bluing
Mrs Stewart's Liquid Bluing is a simple, concentrated blue liquid
that optically whitens white fabric. It does not remove stains,
does not "clean", but adds a microscopic blue particle to white
fabric which has been giving fabric that "just bought" whiteness
for 120 years! The most effective, safe, versatile, economical
laundry whitener available! Mrs. Stewart's Bluing is nontoxic,
biodegradable, non-hazardous and environmentally friendly. Made
of a very fine blue iron powder suspended in water ( a "colloidal
suspension"), a nontoxic amount of a pH balancer and a biocide
to prevent the buildup of algae and bacteria.
