The Caloric Cookstove may have been standing closed for a considerable length of time before its receipt by a purchaser and for this reason, the linings should be thoroughly washed with clean water and soap, or scalded with boiling water. They should then be wiped perfectly dry and the covers allowed to stand open for several hours, in order that the compartments may be thoroughly aired. After each use of the Caloric, it should be washed clean and wiped dry. The covers should be allowed to stand open when the cookstove is not in use. If they are tightly closed when the Caloric is not in use, the lack of air may cause the cookstove to give off a musty odor and this odor may sometimes be imparted to delicate foods. It is well understood that a room or a house when closed up tightly becomes musty and the same is true of the Caloric in a greater degree because the metal compartments are practically air tight. A good housekeeper does not put away cooking utensils with the covers on them as they would not keep sweet under such conditions.

When convenient the cookstove should have a thorough airing out of doors at least once a week. If it is not convenient to do this, the stove should be placed in front of a window, where the sun may shine in the ovens.

When cooking, the utensil covers and the steatite radiators must be properly in place before any attempt is made to shut the covers of the stove. Otherwise, the metal may be dented.

It should be remembered that the action of heat and steam in the Caloric stoves is very severe. Therefore, the metal lining cannot be expected to remain bright. The heat from the radiators will darken it. The chemical action of acids in some foods will discolor any metal, no matter what it is. This discoloration in no way affects the cleanliness of the stove, hence no attempt should be made to keep the lining bright by scouring it with gritty soaps or powders. Such a proceeding will scratch the surface of the metal and may, eventually, start rust or corrosion. The oven in an ordinary range does not remain perfectly bright and the Caloric oven should not be expected to do so. Water or moisture should never be allowed to stand in the metal compartments.
