Default Polish for tarnished metal

Is there a polish or cleaner I can use to remove tarnish from the bare metal wings on my GJ200 DC-9?

I don't know if this will work but it's amazing on car body work.

Clay bar, gets rid of swirl marks so may be ok. Though it maybe a little big for a model.

Also, it looks like all the polished metal models have a clear coat of varnish on them, so it's not exposed. Would this Clay Bar work through the varnish?

I hate to be the bearer of bad news, but I don't think it is possible to remove the clear coat without removing the paint underneath. And once you did remove the clear coat, because it is the actual metal that is tarnished and not the clear coat, you would have to repolish the wings to get it right. And then repaint any details on the surface

Unfortunately, the 'tarnish' or stains is the downside to most polished models. There are VERY few polished models that get it right. Most come from the factory with the 'tarnish' already there.

Clay bars are used to remove contaminants from auto finishes prior to polishing and waxing. they are wiped across the paint using a lubricant ( soapy water) . it is NOT a polish by any means and I would say useless on a model.

Show me one professional detailer who uses a clay bar to get rid of swirl marks.

I have this sort of damage to my model.
Its impossible to polish out, I have to disassemble the model, strip the paint and repaint.
As I already have plastic kits waiting for a paint on my workbench, I decided its not worth doing.

That's exactly what the wings of my IF 200 AA BAC-1-11 look like now. Fortunately, it's only on the bottom of the wings, so it doesn't show so much. But it's a shame it happens to some polished metal models, frustrating when you get them new and they're perfect.

I have other polished metal models that still look fine, such as most of my GJ 200 AA models, and even though Hobby Master doesn't always do such a good job in the accuracy department with a lot of models, the AA DC-4 and AA L-188 Electra I have from them look great after 3 or 4 years!

What's the point of suggesting something only to have the hands thrown up in the air saying "it's impossible"?

Try Goddards as suggested above.
It is a fine silver polishing compound applied with a foam pad applicator. Put some on the foam pad which comes with the jar, wet it and apply. Once finished, rinse in warm water.
I've been an antique collector for many years and have an extensive sivlerware collection and use nothing else and never has it caused issues.

If my first suggestion isn't satisfactory, try using a wire brush and hydrocholoric acid.

If there "is" a Clear coat over the polished metal as some here have pointed out, no type of metal polish will help.

Then my second suggestion is perfectly sound.

I think that's about all you can do- trying silver polish or anything else risks damaging the model.

For something with a simple shape like a wing (as with the picture above or the OP's DC-9 wing) you could get away with covering the wing with some Bare Metal Foil Bare-Metal Foil Co. You can actually get it to confirm to some pretty complex shapes if you plan correctly.
