Hitherto oxalic acid has been used to neutralize the traces of alkali remaining after the clothes have been washed in soap or and stiff and weakens their fiber.
another detergent so as to enable the bluing to set, and also to remove iron and other stains, and particularly the yellow edges of collars whlch are largely due to the iron .in the blood given off in perspiration. But
oxalic acid makes the clothes feel harsh This is due to the fact that oxalic acid unites with the lime. which is usually present in the clothes or in the washing tank (especially if chlorid of lime has been used as a bleach) and forms calcium oxalate in the form 0 a .fine white, and insoluble powder. This substance settles into the fiber of they clothes, and, beinginsoluble, is rarely removed by the rinsing process. After repeated washings the cloth becomes filled withthis powder, feels hard and stifi, the fibers are weakened, and the turned edges break.
My improvement consists substantially in treating such fabrics wit fluori ilill the form of any of its water soluble compounds which have an acid reaction. For instance, I may use hydrofluoric acid, hydrofluosilicic acid or any of the water soluble salts, such as the acid salts of the alkalis, for. instance, sodium acid fluorid, potassium-acid fluorid, ammonium acid fluorid, or sodium silico fluorid ammonium silico fiuorid or potassium silico fluorid. On account of its cheapness, the sodium salt of hydrofluoric acid is probably the salt best adapted forpractical use, although the ammonlum salt is more readily soluble. These substances do not form aninjurious precipitate and are easily removed by rinsing.

mixture of two or more fiuorin compounds of the character described.
In using the substances above referred to, I add about one pound to about every thousand pounds of the laundry water (without soap), this treatment preceding immediately the usual addition of bluing, to the laundry water. -In order to neutralize the alkali in the laundry water without using for this purpose the expensive fluorin compound, I may add acid, such as search Hoom Patented F b. 13, 1912. Application filed December 2, 1909. Serial No. 531,096.
acetic acid, by adding the same to the laundry water previously to or simultaneously with the fluorin compound. Such acid may first be mixed with -the fluorin compound and the mixture then add'ed to the water.
I may also employ m improvement in the art of cleansing fab its by mixtures such as fluorincompound or compounds with a gum to form a paste. 'This paste may be applied directly to the stains and this method of employing my invention is of particular value when it is desired to remove very heavy rust stains.
My improvement in the art of cleansing fabrics results in the neutralization of the alkalis and the removal of rust stains and a large number of other stains in which iron ispresent without injury to the fabrics, which is an entirely unexpected result, since hydrofluoric acid and many other water soluble compounds of fiuorin are commonly believed to have a strong destructive action. i J
