Whiten white clothes safely! Non-toxic. Bio-degradable. Standard of excellence since 1883. Why Bluing? White fabric turns yellow or gray with age and repeated washings. Bluing restores the sparkling whiteness. Works on synthetics as well as natural fabrics without harming fibers like bleach can. Magic Salt Crystal Garden: Write for directions to make this fascinating project showing crystal growth using common household ingredients. Great for science projects, scout troops, schools, etc. So many other uses! Use Mrs. Stewart's Bluing in swimming pools, bird baths, for white hair and pets, for cleaning crystal and glass, and more!
