Turpentine should work.
In California we have lost many of our solvents like paint thinner and naptha due to its polluting qualities.
But we can still buy charcoal starter, which is similar enough to paint thinner and I have been using that as a useful solvent.
Alcohol might work, but the risk to a shellac finish is too great, paint thinner or "charcoal starter" is probably safer (though smellier).
You could also try just another application of Pledge as it might dissolve enough of the old residue to work as a cleaner.
WD-40 might work too, or Goof-Off.
You also might want to just try a simple cleaning agent (I use Spic n Span) and some elbow grease.

Subject: Pledge built up
Greetings all,
a customer called me and wanted to know if there's anything that can be done to remove the build-up of pledge products that were used for many years to clean the piano.
It has left a milky/hazy residue.
The piano is an Essex upright with a polyester finish.
Thank you,
Peter
