Removing a dried out finish
I have recently acquired a 1950's 3 piece lounge in what I think is a rosewood colour finish. A large portion of the surface has an orange colour finish that I can scrape off with my fingernail. The ends of the armrests that are constantly handled look okay. I think the dried out finish is just years of polish buildup (aka Mr Sheen) and that underneath I should find an intact original polyurethane finish.
If this is correct, how should I get it back to the original finish?
If I'm not correct, then what is the likely situation and solution? Thanks.
