The picture was sent by an inspector. The job is a residential service panel upgrade that is on the exterior of the building. The location is southern California 45 miles from the ocean.

Have no clue as to what it is or what caused it. It is showing up in seven spots on the breakers. Anyone have an answer?

That seems to be a issue that Siemens seems to be known for, it seems to be the compound that they use to prevent tampering with the screw used for calibrating the breaker, not sure if it was common to earlier design Gould/ITE, & ITE breakers that were introduced about 1979.
