Charles:
You can use wool lube and steel wool. Be careful not to rub too hard... But I found a better way, which is to use fine pumice and a damp cloth or sponge. Wet the sponge, wring it out and sprinkle some pumice powder on it. Rub in the direction of the grain/scratch lines. Don't rub too hard but let the powder do the work. Clean up with a clean and damp cloth and remove all traces of moisture. It's easier if you remove the fallboad first so nothing gets on the keys.
Good luck.

Subject: [pianotech] scratch removal
I want to remove the surface fingernail scratches on a Steinway fallboard and generally improve the overall look of the case. Black (satin) finish. I remember some postings about this in the past but can't gain access to the archives beyond the past two months. McGuires auto finishing polish? Wool-wax and steel wool? All suggestions welcome because it would be good to get this right the first time. Happy Holidays all.
