As soon as possible after the aircraft is
recovered from water immersion,
thoroughly wash all internal and ex-
ternal areas of the aircraft using a wa-
ter/detergent solution as follows. Mix
liquid detergent (MIL-D-16791, type
I) and isopropyl alcohol (TT-I-735) in
ratio of eight parts detergent, to 20
parts of alcohol. Add the deter-
gent/alcohol mixture to 72 parts of tap
water and mix thoroughly. For use,
add one part of the preceding concen-
trate to nine parts of tap water (warm
water if available) and mix thorough-
ly. If the above specified deter-
gent/alcohol materials are not availa-
ble, use water-emulsion cleaning
compound (MIL-C-43616). Add one
part compound to nine parts water. If
the MIL cleaning compound is not
available, use any available mild
household detergent solution with
fresh tap water.
