Industrial grade oil?

Maybe some leftovers from this

Seems that the former owner greased the hairspring to avoid squeaky noise. LOL!

A mild acid solution to remove surface rust from other parts, oil and grease disappeared and the hairspring is clean as a whistle now, at least it looks that way.

All other parts only needed the ordinary cleaning solution.

Everything looks like new and I expect it to work like new when I have put everything together tomorrow.

The green stuff looks like 2-stroke engine fuel oil

The oil/grease contained acid and really did affect the surface, but cleaning and a bit of buffing removed almost everything.
A new mainspring will complete the resurrection from the grave.

That is mindblowing. It's amazing what passes thru your bench.

Amazing resurrection. It’s great to see these movements being saved from time, neglect or the well-intentioned (but perhaps unhelpful) efforts of former owners/restorers.
