46. Milk utensils for farm use should be made of metal and have all
joints smoothly soldered. Never allow them to become rusty or rough
inside.
47. Do not haul waste products back to the farm in the cans used for
delivering milk. When this is unavoidable, insist that the skim milk
or whey tank be kept clean.
48. Cans used for the return of skim milk or whey should be emptied,
scalded and cleaned as soon as they arrive at the farm.
49. Clean all dairy utensils by first thoroughly rinsing them in warm
water; next clean inside and out with a brush and hot water in which a
cleaning material is dissolved; then rinse and, lastly, sterilize by
boiling water or steam. Use pure water only.
50. After cleaning, keep utensils inverted in pure air, and sun if
possible, until wanted for use.
