LAUNDRY DETERGENT
The detergent/oxygen bleach is intended for
shipboard laundering of cotton, synthetic, and
blended items using fresh water or seawater. It
is referred to as the two-shot detergent because
it includes a detergent and oxygen-based bleach
and is mixed and ready to use. Since it is premixed
you won’t have to proportion laundry chemicals
as in the past. As long as you add the correct
amounts to the washer, the chemical proportion
will be correct. Figure 5-9 shows the wash sizes
and the amounts of two-shot detergent that should
be used with fresh water and seawater.
The two-shot detergent uses an oxygen-based
bleach that is safe in washing all fabrics, therefore,
the problem in damaging colored clothes with
bleach is eliminated. The bleach is an integral part
of the detergent and will not require special
handling as it is not reactive to the other
ingredients in the formulation. The detergent/
oxygen bleach releases a sharp, unpleasant
solvent-type odor into the air while being used.
You should not be alarmed by this smell because
the smell will not be transferred to the clothing.
WASHING FORMULAS
The Navy recently changed all Navy wash
formulas to include the two-shot detergent. The
new wash formulas were developed by the Navy
to help shipboard personnel produce whiter and
brighter washes. The formulas are illustrated in
figures 5-10 through 5-12. These formulas have
been tested in laundries aboard ship and have been
found satisfactory for the type of work indicated.
These formulas were developed to conserve energy
and to meet environmental regulations while
providing quality laundry. These formulas should
be posted on the wash deck for laundry personnel
to read and follow.
RINSING
Rinsing removes soil and cleaning solutions
from the clothes. Poor rinsing results in grayness,
disagreeable odors, harsh finish, and generally
poor quality work.
The number of rinses used should always be
according to the Navy wash formula you are using
and should not be modified. Under normal
conditions, following the Navy wash formula in
regards to the number of rinses, the rinse water
levels, water temperature, and time of running will
bring desirable results. If clothes that are heavily
soiled do not come out clean in the first wash they
should be washed again according to the Navy
wash formula.
LAUNDRY SOUR
Laundry sour is added to the last rinse to
neutralize the remaining alkalies and to dissolve
