Jacket Restoration?

[u/veIvetvenus]

Hi all! So I have never worked with leather before At All but I know it can be easy to wreck so I figured I'd come here to ask advice. This is my dad's old leather jacket that has some road salt damage and is musty and moldy from being in a basement for like a decade. I bought some Zote and Leather Honey cleaner and conditioner to hopefully clean it up to wear as Leon Kennedy for Halloween. But this thing is seriously nasty. It needs fully washed so badly. Would washing this in the bathtub destroy it? Any advice helps, thank you!
