Machine oil should be washed out in cold water before the article stained with it goes to the laundress.
Javelle water is an antidote for iron rust.
Valuable plaster casts are best cleaned by professional plaster-workers. Small pieces that have become soiled may be made more sightly by covering them with whiting and fuller’s earth, wrapping them in a cloth and leaving them for two or three days. When the powder is brushed off much of the grime will go with it.
TO PREVENT BREAKING GLASS
In opening a jar of fruit with a knife always insert the blade between jar and rubber. Prying against the thin edge of the cover bends it out of shape, perhaps ruining it for future use, and is likely to break the glass.
TO CUT PLATE GLASS
To cut a piece of plate glass it is thought a diamond-cutter is necessary, but it is not. If the glass is not very thick it can be cut with a pair of scissors, a large pair being preferable. While cutting hold the glass beneath half a foot or more of water, and it can be readily cut any shape desired. A round piece of glass has been cut out of a good-sized pane in just this manner. The scissors do not have to be extra sharp.
