1. Cleaning residual lubricant and water contamination from the connectors each and every pre-deployment is as
important as applying lubricant! This can be accomplished using a toothbrush with vinegar [corrosion] & alcohol [old
lubricant]. We recommend flushing all SONDE bulkhead ports out using vinegar between deployments to remove
any contaminates before reinstalling sensors.
The image on the left shows an attempt at lubricating, but just applying a big glob of Kyrtox and shoving the connector
in the port does not always cover the rubber around the pin in keeping water off the pin. The image on the right shows
what happens when the SONDE WETMATES are not properly serviced.
BEFORE AFTER
CLEANING! -- Battery cap after cleaning -- all contaminates removed before lubricating.
