water with a brush or sponge. Rinse thoroughly in clear cold 

 water. Repeat if necessary. 



(6) Soak in sour milk and salt or in buttermilk and salt. Cover 

 the stain with salt and expose to the sun. 



(c) Wet the stain thoroughly and cover with cream of tartar. 

 Proceed then as in (a) . Most ink stains will yield to this treatment. 



For Delicate or Colored Fabrics. Wet the stain thoroughly and 

 cover with cream of tartar mixed with an equal bulk of salt. Sponge 

 very lightly with clear water and expose to sulphur fumes. If the 

 color is affected, apply ammonia with a camel's-hair brush or a 

 medicine dropper and follow with an application of chloroform. 

 Repeat if necessary. 



(d) For Stubborn Spots on Heavy White Goods. Wet the stain 

 thoroughly and rub in salts of lemon or oxalic acid with a small 

 stiff brush, keeping the stain over a hot plate as in (a). Sponge 

 with ammonia and bleach with sulphur fumes or Javelle water as 

 in (a). Rinse in clear water. Salts of lemon and oxalic acid are 

 very poisonous if taken internally. 



PROJECT X. How to Remove Grass Stains 



(a) Sponge out the stain while it is fresh with clear water. If 

 this is not sufficient, sponge the stain with alcohol before it is set. 

 Do not use alcohol if the stain is several hours old. 



(6) Another effective method for fresh stains is to cover the stain 

 with lard, allow it to stand thus for 24 hours, and then wash with 

 hot water and soap. 



(c) If the stain is old, the green coloring matter of the grass has 

 undergone chemical changes by being exposed to air. Alcohol 

 will then change the green spot to a dark brown spot that will not 

 wash out. Wet an old stain and apply cream of tartar and salt in 

 equal bulk. If this leaves a light brown stain, sponge it with water. 

 If colored fabric is affected by this treatment, sponge with ammonia 

 and follow with an application of chloroform. 



(d) An old grass stain on white goods may be removed by bleach- 

 ing with a mixture of equal parts of clear water and Javelle water.
