Best technique for removing pore n wipe polyurethane. Acetone, or other stripper, card scraper?
Google says Klean Strip Premium and Citristrip can remove wipe-on polyurethane, though you might have to let the product sit on the finish longer.
You might follow up with a paint remover wash to final residue. I expect some sanding will be required.
Most solvents will damage bindings if you have them. I did one successfully by scraping.
Though I have not refin'd a poly coated banjo in 40 years, I remember heating the finish with a hair dryer made it easier to remove.

Mind if I ask why?
Maybe there are other remedies that don't require removal to wood.
I've not had to remove poly, but Citristrip does a good job. I tape off celluloid just in case and scrape the finish near it.
A good, sharp card scraper is really fast, with minimal exposure to chemicals.

Be very careful using heat to remove poly finish if you have plastic binding. DAMHiKT.

Many single edge razor blades.
