Please make sure the type of piping you have before using anything. Plastic is great with acid, metal not so much. Metals will weaken with acid

All the original plumbing is cast iron. I’ve done some renovations to the upstairs and replaced what I could. But haven’t touched the basement stuff yet.

Oof.... Not acids then... I would stay far away from putting acids in old Iron.... Unless you have a longer powered snake, you might just need to call a plumber. Hell call a few, just to ask what chemicals are safe. They may be cool?
