loose particles. Parts are to be free of any oil or grease except
for lubrication as specified in this instruction.
2. Cleaning agents used shall be such that effective cleaning
is assured without injuring the surface finishes or material
properties of the part.
3. Acceptable cleaning agents include demineralized water,
nonphosphate detergent, acetone, and isopropyl alcohol. Parts
