Tarnish / Oxidation on Tuner Gold Plated Faceplate



Hi,

I had just acquired a pre-owned Magnum Dynalab Tuner with a gold plated faceplate. I reckon the Tuner is about 20 years old and I noticed there are some tarnishes and stain marks that resemble oxidation on the faceplate due to age. Can anyone share some tips on how to remove these tarnishes and stain marks/oxidation from the faceplate?
Would greatly appreciate your advice and tips.

Many Thanks

Thanks Roxy for the comprehensive explanation and information pertaining to tarnishes and oxidation on plated surfaces. With regards to stripping and re-plating the faceplate I think it is going to be a challenge as the existing black letterings and wordings (not sure if they are silkscreen letterings) on the faceplate will also be removed during the stripping process. Unless these letterings/wordings had been embossed on the faceplate, they will be gone forever after stripping and re-plating.
Well, I guess I will just have to leave it as it is and wipe it with a clean microfiber cloth occasionally. Thanks again.
Try Weiman glass cook top cleaner. I use it on my chrome amps to remove tarnish and oxidation and it does a great job! I think Walmart sells it.
