    White residue/corrosion on marantz faceplate?

    As the title suggests I am looking to figure out he I can get some weird corrosion/residue spots removed from marantz equipment I just purchased. I read around a bit and it seems that you should use some sort of polisher, but I figured I'd ask just to be safe.

    Just purchased a MINT Marantz 6200 at an estate auction. What next?

    I won an auction for a Marantz 6200 a few days ago and picked it up today. I was hoping it would be clean and absent of too much damage but this is blowing my mind. This thing is in perfect condition. Even the shell looked flawless other than what looked like a recent scratch, probably from...
