Thanks for your thoughts.

I'll try that. Thanks.To take care of restoring the stem manually, you can use Mr. Clean Magic Eraser on the stem to rid the oxidation. You will burn through quite a few of these pads to get the job done, but it is gentle enough on the stem. Then you can finish the stem up by polishing it with Micro MESH Sanding Pads. These supplies are pretty cheap on Amazon.
I'll try that. Thanks.
