Thanks for all the comments.

The house is roughly 90 years old now depending on what document to
believe.

90% of what I want to clean is possibly replaceable. However 10% is
irreplaceable ornate wood, so I may want to focus just on that.

I used PeelAway as a sample on one door and frame and it took me three
weekends, $100+ worth of product, and I still never got more than 90%
of the paint off- which means for a 7 ft door we had about 10 inches
of paint left on. Then the glue that held the wood together dripped
off and the panels started to warp. Peelaway basically didn't work
even thought it worked the best of all the chemical peels.

I think I'm going to just buy a heat gun used and test it out.
