8. Some form of insulation is recommended for use over utensils 

 which are being sterilized in a cold room. A blanket easily can be 

 made for this purpose. This is desirable in order to keep the cans 

 or pails hot long enough after the sterilization to dry out quickly. 



9. Cans should be dry in one or two minutes after removal when 

 placed upright. If they do not dry within that time, they have not 

 been sufficiently heated or were not washed clean. 



10. The drying of dairy utensils after washing and sterilization 

 is extremely important, for bacteria may develop in a moist can. 



11. After the utensils are sterilized and dried, they should be 

 placed in a room free form dust and should not be touched until 

 milk is placed in them. Pails after steaming and drying should be 

 placed upright in a clean, dry, covered wooden or metal box, where 

 they should remain until milking time. 



12. The sterilizer has been designed with the intent of making it 

 both cheap and simple, to give the desired results. Satisfactory 

 results should follow its use. 



13. When using a kerosene or gasoline stove the sterilizing should 

 be done in a room where milk is not handled, as the milk may absorb 

 the odor of the oil. 



14. The sterilizer may be used advantageously for separator parts, 

 which should be steamed in the box used for can tops. In case they 

 do not fit, a special metal box should be made. 



15. After use, the parts of the sterilizer, especially the roasting 

 pan and cover, should be cleaned and wiped dry, to prevent rusting. 



16. The sterilization of dairy utensils is a matter of very great im- 

 j)ortan.ce, and producers are urged, for their own advantage, to 

 prevent the introduction of vast numbers of bacteria into their 

 milk from unsterilized utensils which may look clean to the eye. 

 Under ordinary circumstances macteria grow rapidly in milk and 

 spoil it, thereby causing losses to the producer and others.
