Connector interfaces, especially the outer conductors on the SMA connectors, should be kept clean and free of dirt and other debris.
Isopropyl alcohol applied with a cotton swab applicator is recommended for cleaning connector interfaces.
Note
Most cotton swabs are too large to fit in the smaller connector types. It is necessary to remove most of the cotton and then twist the remaining cotton tight. Be sure that the remaining cotton does not get stuck in the connector.
The following are some important tips on cleaning connectors:
• Use only isopropyl alcohol as a solvent.
• Always use an appropriate size of cotton swab.
• Gently move the cotton swab around the center conductor.
• Never put lateral pressure on the center pin of the connector.
• Verify that no cotton or other foreign material remains in the connector after cleaning.
• Only dampen the cotton swab. Do NOT saturate it.
• Compressed air can be used to remove foreign particles and to dry the connector.
• Verify that the center pin has not been bent or damaged.
The following illustrates how to properly clean connectors.

2 – Use only isopropyl alcohol and the proper size of cotton swab. Gently rotate the swab around the center pin being careful not to stress or bend the pin or you will damage the connectors.
3 – Do NOT put cotton swabs at an angle, or you will damage the connectors.
4 – Do NOT use too large of cotton swabs, or you will damage the connectors.
