370. Rust.

If rust has made its appearance on grates or fire-irons, apply a mixture of two parts of tripoli to one of sulphur, intimately mingled on a marble slab, and laid on with a piece of soft leather. Or emery and oil may be applied with excellent effect; not laid on in the usual slovenly way, but with a spongy piece of fig wood fully saturated with the mixture. This will not only clean but impart a polish to the metal as well.
