To Clean the Back of the Grate; the Inner Hearth; and of Castiron Stoves, the Fronts
Boil about a quarter of a pound of the best black lead, with a pint of small beer, and a bit of soap the size of a walnut. When that is melted, dip a painter’s brush, and wet the grate, having first brushed off all the soot and dust; then take a hard brush, and rub it till of a beautiful brightness.
