I have polished the Yamaha letters on my G7 several times over the years and just used whatever metal polish I had around. Ended up nice and shiny and did not hurt the finish. That's all any 'pro' would do.

Ah, this reminds me, I have a polishing cloth for silver around here somewhere. I wonder if that would make any improvement (even without using anything). I'll have to google about the vinegar, I've heard vinegar is actually quite strong (hence its use as a cleaning agent).

Re Lady Bird's comment (IIRC), it doesn't look that bad up close, but because it's sort of dulled, it looks worse IMO from far away.

Anyway, I definitely don't want to make it any worse, so that will be my guiding MO!

You may end up making things worse.

Also, in this situation, once you remove any top coat covering the brass letters, the brass will then tarnish much more quickly in the future.

If you leave this to a professional they can take responsibility if things go wrong.

It's about a 2 minute job. I have done it several times and so have many others. You will not cause any damage and it will look beautiful.

Well I’ll try it I guess. But we’re not going shopping for another two weeks probably so I’ll either have to order something or wait...

Another thing: if making brass shine is like making silver shine then standard toothpaste works like a charm. Just put some toothpaste on it and wipe it gently away. No rubbing required - seems to be a chemical effect rather than a mechanical one. I strongly suppose that toothpaste does also not damage the polyester of the piano. Again: this works like magic on silver - not sure if it works also on brass. There was however also another gentleman in this thread who suggested toothpaste.

I can't find it! whome Mr. SK said he thinks he knows where it is, so I'll try that first.

Re the toothpaste, if I do that, should I just use a cotton cloth? No added water? I could try on some other brass part first...

dogperson, I think I may have read exactly that webpage when this thread first started. But unfortunately, I don't have many of the main ingredients for the make-it-yourself ones (no lemon, no flour...)

The other thing that is as yet unresolved is whether there's some kind of coating on top of the lettering. Does anyone know how I would be able to tell?

Since your piano is glossy poly, I would look at it sideways from an angle. I guess you then would see a clear coat running on top of it. My guess is that the glossy poly finish on your piano would be similar to the glossy finish on my parent's 90s U1 and my friend's 00s GC1, i.e., the Yamaha letters are underneath a clear top coat.

Like @BDB said, if you want to clean it, you might have to remove the top coat on the letters to access to them and doing that might damage the whole finish of the piano. I would just leave it alone in your case. The letters do not look that bad in your picture.

On the other hand, my 60's G7 is satin finish, there might be no clear top coat on the finish like glossy as I can't see any. I guess if the top coat on the Yamaha on my piano had ever been there, it might have got rubbed off frown

If you want to know if there is something over your brass letters maybe you have an ohmmeter or a continuity tester available. If it is just metal it should be easy to tell with either one of those.

If I touch the brass with the probes of my tester I immediately get a beep. I do not have to pierce through anything to close the circuit. Apparently my letters aren‘t covered with anything.

The article I attached includes toothpaste instructions: nothing but toothpaste and water required.

Dig out a magnifying glass and flashlight. Magnify the surface as much as possible. Call on your inner MacGyver. smile

I have experience of cleaning brass fittings with Brasso. A major problem is that if the Brasso gets into any tiny cracks or crevices, it dries to a white powder/coating in the crevices which is near-impossible to remove. It is possible that the same could be true of toothpaste.

May I re-iterate my lemon juice preference for cleaning bras at this point :-)

It also doesn't scratch like toothpaste or even brasso might, although such scratches would hopefully be very fine.

We don't have lemon juice, and are on quarentine-shopping schedule (no shopping for another two weeks). But I may try it... I still have go and check to see if I can tell if there's a coating.

First I need to get off of this computer... whome
