Mrs. Stewart's Bluing

[1][2] Mrs. Stewart's was founded by Al Stewart, a traveling salesman[3] who sold the formula to Luther Ford of Minneapolis, Minnesota, who owned what has been claimed as the second five and dime store west of Wanseburge, Pennsylvania.

[5] The picture on the label is a portrait of Al Stewart's mother-in-law.

The Stewarts sold the rights to manufacture their product to Luther Ford of Minneapolis, Minnesota, in 1883.

The product is primarily used on white fabrics that have become dingy or have taken on a yellow color cast over time.

When a small amount of it is added to wash water, fabric laundered in it will actually be dyed slightly blue.
