CLEANING MATERIALS AND METHODS
1.
Refer to TM 9-247 for cleaning materials to be used.
WARNING
Drycleaning solvent P-D-680 is toxic and flammable. Always wear
protective goggles and gloves, and use only in a well-ventilated area.
Avoid contact with skin, eyes, and clothes, and DO NOT breathe
vapors. DO NOT use near open flames or excessive heat
2.
Cleaning is normally done by the dip-tank and/or vapor-degreaser methods, or by cleaning with cloths soaked in
drycleaning solvent (Item 12, Appendix C).
f
CLEANING OF MATERIEL RECEIVED FROM STORAGE
1.
Materiel received from storage by Direct Support maintenance units will be cleaned by the dip-tank, vapor-
degreaser, or steam method, whichever is applicable or available.
WARNING
Drycleaning solvent P-D-R80 Is toxic and flammable. Always wear
protective goggles and gloves, and use only in a well-ventilated
area. Avoid contact with skin, eyes, and clothes, and DO NOT
breathe vapors. DO NOT use near open flames or excessive heat.
(a)
Dip-Tank Method. Disassemble as required and place parts in a perforated metal basket. Submerge and
agitate basket in a tank containing drycleaning solvent (item 12, Appendix C). Repeat using a second tank
with clean solvent. Extent of treatment in each tank will depend on ease with which parts are cleaned.
(b)
Vapor-Degreaser Method. Tanks containing a heated solution of perchloroethylene (Type II) or other
degreaser are used for degreasing items that are very greasy or oily and are not readily cleaned by the dip-
tank method. Place parts in a perforated metal basket and submerge below the vapor in the tank. Keep
basket in this position until all grease, oil, or dirt melts and runs off the parts. If necessary, material may be
washed with degreasing spray unit.
(c)
Steam Method. Place parts in a perforated metal basket and steam-treat until clean. This method is less
efficient than vapor-degreaser method, and parts may require additional cleaning to remove final traces of
grease, oil, or dirt, particularly from recesses.
2.
If some time is to elapse before the start of repair or overhaul operation, apply a coat of corrosion preventive (Item
11, Appendix C) oil to all finished metal surfaces to prevent rusting.
