My neighbor had a gift piano moved, and unfortunately, the movers put a
leaky tarp on it and it got wet. Then my neighbors didn't uncover it as
soon as it arrived and it sat, covered and wet, for days. Now, of
course, it looks awful.

However, even though the finish is ruined, any veneers don't seem to
have lifted, which is good.

What typical finishes were used on older pianos? I suggested she test
for shellac with some denatured alcohol and a bit of rag. If it wasn't
shellacked, what other finishes might have been used, and how could she
proceed in refinishing it? I almost exclusively use shellac, danish
oil, or spar varnish for bright finishes, and there my experience ends.

Thanks!

What does her damage look like? White cloudy film? White spots?
Black spots?

Try rubbing an inconspicuous spot with lacquer thinner, to see if the
finish is lacquer.

Grand pianos can have a lacquer finish and/or rubbed oil finish.
Black lacquer was/is a long time favorite.... often a dozen or 2 or 3
of polished in coats.

Not really cloudy. Very dull, roughened, sort of wrinkly in spots.

The same test you used for shellac (applying a small amount of alcohol) should
also work for lacquer (apply a small amount of lacquer thinner). If it's
lacquer, the finish will dissolve in the same manner as shellac (and then "dry"
back to a cured state). Sounds to me like it's probably an oil based varnish
of some kind. Lacquer thinner might also attack that (or not), but in that
case the finish would not dissolve but would break down, congeal, and be ruined.

Scritch, before you try to refinish, try working on the rough spots with
Restor-a-finish and 0000 steel wool. Read the instructions carefully.

If it doesn't work, then you can refinish. The stuff has fixed some
amazing messes for me though.

Home Depot, True-Value and DoItBest hardware stores generally have it.

Might be worth a try. I'll suggest it and see what happens. However,
the "rough spots" are the whole piano. The only good finish left is
inside the keyboard cover.

Hope the mover is insured.
