I've tried various chemicals over the years, those especially made to remove finishes and had no success with any of them. They turned everything into a gooey mess that 3 different coatings still required me to in the end, scrape off what was left, but then, there was risk of damage as the mess remained somewhat of a goo and you were actually scraping off a bit of wood along with the goo to get it off.
Denatured alcohol was one that I haven't tried so it may be worth a shot. But I've had very good success with my method as well with no ill effects.
