CARE OF THE SINK.--If the sink is of porcelain or enamel, it may be
cleaned with soap, but not with scouring soap or powder. The latter wears
away the smooth finish, makes it slightly rough and hence more difficult
to clean. Before applying soap to a sink, wring out the cloth used in
cleaning it as dry as possible and then with the hand push any water
standing in the sink down the drainpipe. Then apply soap to the cloth and
wash the sink. _Do not let the water run from the faucet while cleaning
the sink._ If the dirt and grease on a sink do not yield to soap, apply
a small quantity of kerosene. After cleaning, rinse the sink by opening
the hot-water faucet, letting a generous supply of water flow down the
drain-pipe so as to rinse the trap.

The drain-pipe and trap of a sink need special cleaning occasionally. This
is often done by pouring a solution of washing-soda down the drain. If
this is used, special care should be taken to rinse the drain with much
hot water. As previously explained, grease and washing-soda form soap. If
the latter is allowed to remain in the trap, it may harden and stop the
drain-pipe. Because of the formation of soap and the possible stoppage of
the drain-pipe when washing-soda is used, kerosene is advised. To use
this, first flush the drain with about half a gallon of hot water.
Immediately pour in one half cupful of kerosene. Let the kerosene remain
in the trap for at least 5 minutes. Then rinse with another half gallon of
water. Kerosene emulsifies grease and makes it easy to rinse away.

SUGGESTIONS FOR PERSONAL NEATNESS IN THE SCHOOL KITCHEN AND AT HOME.--For
both comfort and cleanliness a washable gown should be worn in the kitchen
or the gown should be well covered by an apron. It is advisable to cover
the hair with a hair net or cap. Rings are an inconvenience when worn in
the kitchen. The hands should be washed _before_ preparing or cooking
