Just purchased a 2001 Young Chang E101 with the black glossy finish. I'm happy with the piano. Does anyone know the best way to get rid of light surface scratches in the finish? Looks like it may have been dusted with a rough cloth or perhaps some type of non-compatible furniture polish.

Where can you get this polish? I searched the web, and was told on on old pianoworld thread that Schaff handles it. But, I think you have to be a dealer to buy from them. Any suggestion would be appreciated.

I have had good luck with the Cory Super High Gloss Polish. Many piano stores have it or it is available online.

To get the best results, any polish is best applied, and buffed, with a high quality micro-fiber cloths.

The Unicon and Cory's are more dressings rather than plolishing compounds.

If you can feel the scratch with you lightly drag your fingernail across it then you must call in a cabinet man to buff it out with a machine. Get a recommendation from your local piano dealer.

If you cannot feel the scratch then you may be able to polish it out yourself. Find "plastic polish" at the car parts or motorcycle supply. Several manufacturers make it to buff out face shields and boat windows. Mcguires or Mothers and others make it. Follow directions. Start in an inconspicous spot at first until you perfect your technique.

Marty,

All of what you said is true. However, if you closely read what the OP stated, I intrepreted that as being the miniscule scratches which are inevitable if a piano has been dry dusted. Even a Swiffer will cause them. Dust, in and of itself, is abrasive to any finish.

A good piano polish will fill those minute little abrasions. With a thorough application and the removal of the dried polish, with a non-abrasive micro-fiber polishing cloth, the piano can gleam. After a number of applications, about once a month, the surface created will be better able to withstand a dry dusting. Even with that old linen dish towel which seems so "soft."

It really doesn't seem that Trex' piano requires that it be buffed out using a mildly abrasive polishing compound.

Kieran,

Are you just recommending it because it is a local product for us? wink

Oh, please -

It seems that the "pros" want to get exotic in all sorts of obscure methods to solve the problem.

There is no problem!

The concern is nothing more than the care of cabinetry which is not unlike any wood furniture. Poly, lacquer, or varnish, it is treated the same. The minor marks which can be seen when the light is just right, are covered over with a good polish.

A piano is not the face shield of a motorcycle helmet. Though, Harley riders are overly fastidious about the detailing of their bikes. No need to ride it, just polish it.

"Pro" piano dudes, don't over react to what was a simple question. A single double strike does not require a total re-build of the action.

I appreciate the great advice. I believe I'll try Cory's on a small inconspicious area and inspect the results. If that doesn't work I can always call one of the local San Diego pro's for a $$$ fix. This forum is awesome! Thanks everyone.

Just to get back with everyone concerning this thread. I did use the Cory product successfully. The piano's finish looks almost new again.

Except on those pianos where it does.

If you throw a rod it does require a total rebuild.I used the same stuff to detail my Harley collection as my polyester finish Steinway grands.Come to think of it they have become garage queens lately. grin

The best part of riding a Harley in Minnesota is getting bugs splattered on your teeth.

Then we use them as bait.

Then we use the strings of a piano to grill the catch.

There is nothing better than large mouth bass, slow smoked on a Mapes grill, using Renner wood to add the smoke and unique flavor. The connouisours refer to it as "a slight, felt-like resonance."

To remove the little wings and things stuck in my teeth, I always brush with Cory's.

Trex - are you saying that the Cory's removed the light surface scratches?

Hi Bill - I'm sure the scratches are still there but the product seems to fill in the surface area so they are no longer readily seen. The product is a spray polish, not an abrasive. I'm certain it will require regular periodic applications to keep it looking good.
