Oxalic acid and salts of lemon may be used with care on any kind 

 of vegetable or animal fabric that is white. They will bleach colored 

 fabrics, but the color may often be restored by the use of ammonia 

 followed by chloroform. The most useful acid for removing stains 

 is probably tartaric acid. It cannot be made strong enough to in- 

 jure fabrics, and if the cream of tartar is mixed with an equal bulk 

 of salt, it is not likely to cause colors to run. It is only slightly 

 poisonous. 



PROJECT VII. How to Remove Acid Stains 



Many acids will stain fabrics of any sort. Some acids which 

 will not affect white goods will stain colored goods, especially blues 

 and blacks. 



To Bleach Acid Stains from White Cotton or Linen. (a) Wash 

 the article, dip the stain in Javelle water, and rinse in clear cold 

 water. Or, (6) dampen the stain and expose it to the fumes of 

 burning sulphur. 



To Neutralize Acid Stains in Goods of Any Fabric or Color. 

 Apply ammonia to the stain. In the case of colored silk or other 

 delicate colored fabrics, apply the ammonia very gently. A camel's 

 hair brush or a medicine dropper is recommended for the purpose. 

 Take care not to rub the ammonia into the stain or it may cause the 

 color to run. If the color is affected, apply chloroform to restore it. 



PROJECT VIII. How to Remove Alkali Stains 



White or Colored Goods. If fabrics of any sort are stained by 

 washing soda, lime, or other strong alkalies, moisten the stain with 

 lemon juice, vinegar, or tartaric acid. Afterwards apply chloro- 

 form, if necessary to restore the color. 



PROJECT IX. How to Remove Ink Stains
