To Wash Greasy Tin and Iron
March 2nd, 2017
Pour a few drops of ammonia into every greasy roasting-pan, first half-filling with warm water. A bottle of ammonia should always stand near the sink for such uses. Never allow dirty pots or pans to stand and dry; for it doubles the labor of washing. Pour in water, and use ammonia, and the work is half done.
