The removal of stains from the hands is a comparatively simple matter, though it may not be generally known that the stain remover works equally well with ink stains as with developer stains.

For developer or ink stains, immerse the hands in the following solution:

Water, 32 ounces

Potassium Permanganate, 1/2 oz.

Sulphuric Acid C.P.,75 minims.

Rinse and apply a 5 per cent solution of Sodium Bisulphite or immerse the hands in an acid hypo solution. If the one application is not sufficient, rinse the hands thoroughly and repeat the operation.

This will remove stains caused by any of the ordinary writing or stamping inks as well as practically all forms of developer stains.

Silver stains are not likely to yield to this treatment, however, as silver is much more difficult to remove from the hands. In the days when the photographer silvered his own paper, silver stains were removed from the hands with cyanide, but as this chemical is a deadly poison we would not advise its use for any purpose without a full knowledge of its dangerous character.

For the removal of silver stains we suggest the bleaching solution which is used when prints are to be re-developed. Make up the solution as follows:

When the silver stain has been bleached out with this solution, rinse the hands and immerse them in an acid hypo solution.

To remove the developer or ink stains from white fabrics, the acid-permanganate solution recommended for the hands will also remove the stain from the fabric, but in doing so it is apt to weaken it because of the presence of the strong acid.

The following method is less harmful: Soak the stained portion of the fabric in a 5 per cent solution of Oxalic Acid or Acetic Acid for two minutes: rinse for two minutes and then apply a saturated solution of bleaching powder (calcium hypochlorite). If, after ten minutes bleaching, the stain does not disappear, rinse thoroughly and re-apply the acid solution, and, if necessary, the hypochlorite solution and, finally wash thoroughly. Only the portions of the fabric containing the stains need be given this treatment.

Colored fabrics should never be treated with the acid permanganate solution as it will bleach out the color that is in the fabric. Use the last mentioned method for stains in colored fabrics.

To remove silver stains from white or colored fabrics, bleach in the following solution for ten minutes:

Potassium ferricyanide, 1 ounce Potassium bromide, 1/4 ounce Water, 32 ounces

Then apply an acid hypo solution. Wash the fabric thoroughly and if the stain is not completely removed the treatment should be repeated.

Iodine stains on the hands or on fabrics may be removed by applying a weak solution of hypo or a few drops of an ordinary fixing bath. The hypo should then be removed by washing.
