Force FX connector between Micro-controller board and RF board

This seems to be common corrosion I have been seeing most likely causing intermittent errors including 213 and other dosage errors. It is my opinion that this damage is not "cleanable" as there is pitting and what appears to be amalgamation of the cleaners and breakdown of the different metals in process. It is my opinion that the connector on both sided (Micro-controller board and RF board) should be replaced together to stop the reaction and bring the unit back to working order after calibration.
