2-23. GENERAL CLEANING INSTRUCTIONS.
Drycleaning Solvent (P-D-680) is TOXIC and flammable. Wear protective goggles, face
shield, and gloves; use only in a well-ventilated area; avoid contact with skin, eyes, and
clothes, and do not breathe vapors. Keep away from heat or flame. Never smoke when
using solvent. The flashpoint for Type II Drycleaning Solvent is 140 degrees F (60 degrees
C) and Type III Drycleaning Solvent is 200 degrees F (93 degrees C). Failure to do so may
result in injury or death to personnel.
If personnel become dizzy while using cleaning solvent, immediately get fresh air and
medical help. If solvent contacts skin or clothes, flush with cold water. If solvent contacts
eyes, immediately flush eyes with water and get immediate medical attention.
Never use fuel to clean parts. Fuel is highly flammable. Serious personal injury could result
if fuel ignites during cleaning.
a.
Cleaning Solvents. Use only approved cleaning solvents to clean parts. Drycleaning solvent P-D-680
(Item 38, Appendix C) is commonly used. Always work in a well-ventilated area.
b.
Removing Deposits. Soak parts in drycleaning solvent (Item 38, Appendix C), and wash away deposits by
flushing or spraying. When necessary, brush with a soft bristle brush (not wire) moistened in solvent. Use compressed
air to dry parts, except bearings, after cleaning. Bearings must drip and air dry.
c.
Tools. Do not use wire brushes, abrasive wheels, or compounds to clean parts unless specifically approved in
the detailed procedures. Parts may be scratched or altered and may weaken a highly stressed part.
Do not clean lubricant seals, rubber hoses, or electrical components with solvent mixture.
d.
Rubber Parts. Do not clean preformed packings or rubber parts in drycleaning solvent. Wipe parts clean with a
dry, cleaning cloth (Item 13, Appendix C).
Steam cleaning creates hazardous noise levels and severe burn potential. Eye, skin, and
ear protection is required. Failure to comply may result in injury to personnel.
e.
Exterior Parts. Steam clean all exterior parts thoroughly before removing. This will make inspection and
disassembly easier.
