A Good Cleaning Brush. 
Galvanized iron furnishes one of the most suitable ma- 
terials for the construction of wash sinks. They should 
be provided with steam (or hot water) and cold water 
pipes as shown in Fig. 57. 
Method of Washing. All vessels should be thor- 
oughly rinsed in 
warm water to re- 
move small residues 
of milk and cream. 
The rinsing is fol- 
lowed by washing 
with moderately hot 
water to which a 
handful of some 
cleaning powder has 
been added. The 
washing should be 
done with brushes 
rather than cloths be- 
cause the bristles en- 
ter into crevices which 
a cloth could not possibly reach. Finally rinse the vessels 
in clean water. 
A bottle washer, like that shown in Fig. 58, saves much
