42 To Clean Stone Hearths and Stoves
If you wish to preserve the original color of free stone hearths, wash them in clear water, then rub them with a stone of the same kind pounded fine, let it remain until dry, then rub it off. If the hearths are stained, rub them hard with a free stone. Hot soft soap or soap suds, does very well to wash hearths in, provided you have no objections to their looking dark. For brick hearths use redding mixed with thin starch and milk. Varnished stoves should have several coats of varnish put on in summer so as to get quite hard before being used. They should be washed in warm water without any soap, a little oil rubbed on once or twice a week, improves the looks of them. Black lead is good to black stoves that have never been varnished, but it will not do where they have been. It should be rubbed on dry once or twice a day.
