Tips for deep cleaning/what products to use?

Moving into my new old house in a few days. It hasn’t been lived in for a few months, and prior to that it was occupied by an elderly couple. It’s in good shape but it’s certainly going to need a good deep clean.

I’ll be dealing with yellowing, dusty wallpaper, custom built cabinets and doors, original windows and trim. There’s currently carpet throughout the house but we took a peak under and it seems like there’s some hardwood floors we can bring back to life, so we will be cleaning original hardwood eventually too.

Also the basement is pretty gross, in terms of cobwebs and general junk. But it’s also damp, there’s asbestos covered pipes and old basement stuff we will need to address but she needs a good “cleaning” first so tips on how to go about that would be helpful as well.
