and recesses with compressed air.
(2) Immerse machined metal parts in solvent and scrub until clean, working over all surfaces
and into all holes and recesses with a suitable nonmetallic brush.
NOTE: Flat, wood-backed brushes with soft, fiber bristles are recommended for surfaces;
round brushes, like those used for washing bottles and test tubes, are
recommended for holes and recesses.

sure is recommended for drying.

taching hardware in a suitable cleaning machine, or wash them in isopropyl alcohol (Ref. Fig.

pressed air. Lubricate as required.

er’s instructions.

SUITABLE BRUSHES.
