A Caring for Connectors

Cleaning
Careful cleaning of all connectors is essential to assure long, reliable connector
life, to prevent accidental damage to connectors, and to obtain maximum
measurement accuracy and repeatability. Yet it is the one step most often
neglected or done improperly. Supplies recommended for cleaning microwave
connectors are as follows:
– Compressed air
– Alcohol
– Cotton swabs
– Lint-free cleaning cloth
Compressed air
Loose particles on the connector mating plane surfaces can usually be removed
with a quick blast of compressed air. This is very easy to do and should always be
tried first using compressed air from a small pressurized can. The stream of air can
be directed exactly where it is wanted through a plastic (not metal) nozzle. No
hoses or other connections are needed. Hold the can upright, to avoid spraying
liquid along with the vapor.
Cleaning alcohol
Dirt and stubborn contaminants that cannot be removed with compressed air can
often be removed with a cotton swab or lint-free cleaning cloth moistened with
alcohol.
Alcohol should be used in liquid rather than spray form. If a spray must be used,
always spray the alcohol onto a cloth or swab, never directly into a connector.
Very dirty connectors can be cleaned with pure alcohol. Other solutions that
contain additives should not be used.
NOTE
Use the least amount of alcohol possible, and avoid wetting any plastic parts in
the connectors with the alcohol.
