Javelle water is excellent for removing stains from table linen, or other linen, and if carefully used is quite harmless, but the bleach is a strong one, and if permitted to stand for an instant after the discoloration has disappeared, the material is likely to be weakened, and in a short time a hole will appear.
The water is made as follows:
Sal-sod a, 1/2 pound, Boiling water, 1 pint, Chlorid of lime, 1/4 pound, Boiling water, 1 quart.
Dissolve the sal-soda in a pint of boiling water, and in a separate vessel dissolve the chlorid of lime in a quart of boiling water.
When these two mixtures have dissolved then mingle them, and give the compound mixture a thorough stirring and leave the liquid to cool; when a clear portion will arise, which should be poured off and bottled and tightly corked. The bottles containing it should be kept in a dark place.
To use it, put a little of the bottled liquid into a basin, and wet the discolored linen with clear water, then put it into the basin containing the bleach. The stain should disappear in a moment - not a minute - and the material then at once plunged into clear cold water, and then into another supply of cold water, continuing this long enough to check any further action of the acid.
Only that portion of the linen that is stained should be wet with the javelle water as near as possible.
