It is not an easy matter to remove rust from tools without damaging
them. Better by far is to preserve your tools from rust. Professor
Olmstead, of Yale College, gave the following recipe for keeping tools
from rusting, which deserves to be more widely known: Melt together six
to eight parts of lard to one of resin and stir till cool. It will
remain semi-liquid. Rub on tools or any polished surface in a very thin
film. It will protect the metal from damp and can easily be rubbed off
again when the article is wanted. The resin prevents the oil or lard
from becoming rancid. When too thick, thin down with benzine.
