u/Afraid-Start

I have a Tesla Gen 3 wall connector that I use with an A2Z adapter to charge my J1772 vehicle. It's worked perfectly for the past year. After every charge I unplug the adapter and properly holster the wall connector. Unfortunately, this step was forgotten and the A2Z adapter was left connected to the wall connector and left dangling downwards for a few days and it rained during that time. Water got in the assembly and when I noticed and pulled them apart water spilled out and I noticed corrosion on both the adapter and the nacs plug

How bad is this - is the wall connector or the adapter salvageable?
