After making up the mixture, add 3 to 5 drops of either dilute hydrofluoric acid or a proprietary rust remover. Next add the smallest amount of butyl alcohol which will give a clear solution. The purpose of the butyl alcohol is to mix the wet and dry solvents and a complete and permanent mixture is not obtained as long as the solution remains turbid. After this, add 0.5 part of oleic acid, which will require several hours to dissolve in the mixture completely.
This formula is safe on rayon, silk, cotton, and acetate fabrics, but before use on acetate, it should be tested on a sample of acetate satin.
It is a good stripping agent for tannin stains, such as those caused by coffee, tea, beer, coca-cola, ginger ale, and other soft drinks. If the tannin stain is well oxidized, however, it will be difficult to remove with this or any other known means. The solution is also said to be useful in removing many fruit, ink and dye stains, and to be reasonably safe on most dyed fabrics. |
