[pianotech] Scratched Lid

[Rob McCall]

Greetings all,

Today, I spent nearly 4 hours cleaning and repairing a 12 year old  
Yamaha GH1 for a High School. I don't think this thing has been  
cleaned in the entire 12 years! Also, all the screws on both main lid  
hinges were stripped.  I fixed them using the paper towel /  
cyanoacrylate trick I learned from this list when I first  
joined!  :-)  They ended up being very tight and turned out  
beautifully. (Thanks!)

Well, the insides now look, as told to me by the choir director,  
"brand new!" Next, I'm going back on Saturday to tune the piano and do  
some minor repair work including what I'm describing below.

The problem I want to address now has to do with the surface of the  
lid.  It has a plethora of tiny scratches from, well... years of HS  
kids putting stuff on it, etc.  I'd like to be able to do some work  
and make it look as good as I can. And yes, they are paying me to do  
all this extra work.  :-)

I've attached a photo where hopefully you can see the extent of the  
scratches. What you're looking at is the reflection of the overhead  
lights in the surface of the main lid.

Does anyone have a technique or a secret potion they use to get rid of  
the scratches without destroying the finish? It's a polished ebony  
finish.

Thanks in advance,

Rob McCall
