How to Prevent Rust on Iron and Steel.

1. In the German army oil of gutta percha is used for this purpose. It is applied with a flannel rag and will stand for years. To take off this preservative apply more of the oil, let it remain on the article for from twelve to twenty-four hours, when both the old and new applications can be wiped off. 2. A solution of gutta percha in benzine (consistency of cream) is a simple preservative against rust on metal. Jt can be easily applied with a brush and as easily removed by the application of benzine. 3. Dissolve thirty grains of camphor with a pound of fat, take off the froth and add graphite, until it has attained the color of iron. Wipe off tools, etc., and then apply the mixture and wipe off after twenty-four hours with a soft cloth. This will keep tools or polished iron or steel free from rust for many months. 4. To preserve polished iron surfaces from rust, melt together seven parts fat (tallow) and one part resin, stirring the same until it cools. Apply in a half liquid state; if too stiff, thin with benzine or petroleum. It preserves the polish and can easily be removed. 5. To make a permanent preservative for iron and steel, it is best to use nothing but linseed oil, thickened with a pigment related to the metal itself, and native oxide or a roasted oxide of iron is the best for the purpose. Boiled linseed oil will form a skin, through which no oxidation can take place. 6. Slack a piece of fresh lime in a covered vessel with only water enough to make it crumble. While the lime is yet hot, mix it w’ith enough tallow to make a soft dough and apply this mixture to polished surfaces. As it does not dry to any extent or become hard, it is easily removed. 7. Olmstead varnish or preparation has been in use for many years, and has proved itself perfect, especially for planed and ground surfaces and on Russian iron, which are very sensative tb rust. It is made by melting first sixty grains resin and then one pound of fresh tallow or other grease, when both are to be united. Must be applied while still warm and the surface must be perfectly clean before application. This can also be removed without much trouble. —Industrial World.
