FROM THE PRACTICAL VIEWPOINT 



a considerable extent and is effective, but is more 

 expensive than the machine method. This added 

 expense is principally due to the amount of labor 

 involved in the many handlings of the bottles 

 which is necessary. Various soaking machines are 

 in use. Some of them are so arranged that it is

 ing tank. The solution is made so strong that all 

 foreign matter, even the bottle caps, is disinte- 

 grated. After being removed from the soaker, a 

 rinsing by means of a machine which forces hot 

 water into them renders them sterile. 



Some method of thorough hand washing with 

 subsequent careful sterilizing probably gives bet-

 men who do the washing are careful to see that no 

 dirty bottles get by them. This is an expensive 

 method of cleaning bottles. 



Whatever method of washing is employed, care-
