The connector on my AquaRite T15 salt cell to the AquaRite controller has connection issues, looks like some corrosion inside the connector. What's the best way to clean inside to make sure it makes contact? As long as I press the connector in and get it making contact the SWG system works, otherwise it can't read the salt levels/turn on the cell. The cell has barely been used but was in storage for a while, and some water may have gotten into the connector. Thanks for any ideas!
