Caring for Connectors

Cleaning

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.
Use the least amount of alcohol possible, and avoid wetting any plastic

parts in the connectors with the alcohol.
