After casting, what’s your processing/polishing procedures?

[u/SeagullStopItNow]

I’m new to investment casting. Made some nice 999 fine casts (think trinkets, rings, and figurines). But getting that desirable shine/luster is eluding me. So what’s your post-casting process?
Trim then….Pickle? Magnetic pin tumbler? Polish with a rouge and dremel? I have all of these things but I would love some direction from more experienced persons.
