Cleaning electrical components.
Cleaning compound can cause skin rash and can give off harmful vapors. To avoid injury,
use in a well-ventilated area. Wash immediately with soap and water if compound gets on
skin or clothing.
Remove any corrosion and other contaminants inside the connector or receptacle with cleaning
compound MIL-C-81302 on a pipe cleaner, acid swabbing brush or cotton swab. Remove external corrosion by scrubbing
with aluminum abrasive material.
Put about one ounce of cleaning compound MIL-C-81302, for each connector being cleaned, in an
applicator bottle. Wash the connector shell and pins with compound. Hold connector with openings for pins (sockets)
pointed slightly downward, when possible, while spraying compound into socket openings. This will rinse away loose
corrosion products, dirt and other contaminants.
Wipe away any excess spray with a lint-free cloth.
Before removing any component of electrical system, be sure the
switch is set to OFF, and right battery positive cable is disconnected. You can get
electrical burns if power is on.
Clean dirt, grease, dust and old compounds off cable harnesses and parts by dipping them into
container filled with cleaning compound MIL-C-81302. Shake parts in compound or wipe them clean in lint-free cloth.
Clean dirt, grease and dust from recessed areas with acid-swabbing brush or lint-free cloth. Dry components completely
with low pressure (25 to 30 psi) dry compressed air or with a clean, lint-free cloth.
Remove rust from parts other than connector parts by scraping, wire brushing or both. If rust damage is
too great or is on small thin parts that would be weakened by rust, you may need to replace the part. Find the cause of the
rust and correct the problem.
Cleaning compound can cause skin rash and can give off harmful vapors. To
avoid injury, use in a well-ventilated area. Wash immediately with soap and water
if compound gets on skin or clothing.
Compressed air used for cleaning purposes will not exceed 30 psi. Use only with
effective chip guarding and personal protective equipment (goggles/shield,
