Cleaning

personally, after having tried a series of products, even brand name and therefore expensive ones, I solved it by achieving the maximum result through simplicity.

For black lacquered pianos, I use a Swiffer to remove dust from every corner.

Then I take a soft furniture cloth and wash it in boiling water to remove lint. When the cloth is dry, I spray the "ready-to-use" multi-surface streak-free cleaner onto the cloth and not directly onto the piano.

With this procedure, I eliminate dust, achieve polishing but most importantly, I do not leave any scratches whatsoever on the instrument.

If I may, I would suggest not using wool cloths: let's remember that wool scratches!

Instead, a nice piece of old canvas....but old. Fingerprints are greasy and you have to wait until the next day to remove them. The next day, with the canvas, the polyester becomes shiny again. It is different, however, if the polish is shellac. You can almost never manage to restore a uniform shine. One of the "grandmother's remedies" is to apply some petroleum to the cloth, wait a few hours for it to dry, and then polish. Try it on a small area.

I'm writing the classic heresy, but it works ... at least with my grand piano.

I dust it and then with a dry (super soft) cloth I wipe it with Glassex

Never caused any damage and the grand piano is always sparkling... it looks like a commercial

polyester is fine, but don't overdo it with the glassex.....and use the canvas

If your piano is polyester finished, I recommend trying car polish, but the mild NON-ABRASIVE kind; even better is car wax - always test first on a small area, perhaps on the lower side where it isn't very visible so that if it leaves a stain, it won't be seen.... obviously NEVER TRY THESE PRODUCTS ON OLD PIANOS FINISHED WITH SPIRIT OR SHELLAC!!!

sometimes I have done it and it went well!

I see that everyone is doing their best, thanks for the many and varied suggestions

Can someone with a few easy words describe to me what is meant by canvas, an image for support would be appreciated

I mean cotton canvas. Canvas, a cross-woven warp and weft of cotton thread. Generally, the weave is visible if the texture is intentionally "coarse"; a linen-cotton blend is also fine. An old cotton shirt works well, perhaps one that is a bit heavy. When I go to my tailor—shirtmaker, I enjoy choosing the fabrics and I always like those with a "coarse weave" made of pure cotton. If you have one at home (even a fine weave) that you need to throw away because the collars and cuffs "have left you".... your piano will gladly "wear" it.

I hope I was clear... if I was also likable, I'm pleased... but that's an extra!!!! Bye bye

Hi everyone, I am joining this post to ask two small questions regarding the extraordinary cleaning of the instrument.

On my polished black upright piano, treated in polyester, small, very resistant yellow dots occasionally form. You have to scrub very hard with a damp cloth to remove them. I don't think it is mold because the environment is quite dry. What are they?

On my grand piano, instead, which is dark walnut in color, on the right edge near the music desk, the surface layer of the polyester is quite damaged. It doesn't look too bad, but to the touch, it feels rippled and torn. I bought the piano used, so I don't know exactly what was done to it. How can I remedy this? And how can I deal with small, common scratches?

Thank you.

Probably, I venture, there was a heat source that caused the underlying preparation to surface, or it burned the polyester.
