Wow thanks for all the comments.
So far I have tried...
Barkeepers Friend (This worked well)
White vinegar (I didn't see much effect)
Lemon juice (Suggested by a friend but this did not work too good)
WD-40 (Not bad to cleean that black oxide out)
Dish soap (Again good to get leftover residue off)
Zildjain cymbal polish (Ended up using this last)
I have gotten most of the black marks out and a lot of that stain you see in the picture.
It is at least usable now. Still some stain but hard to see now.
Wright's Copper Cream will be my next try but I have to get some.
As far as weepy songs we don't play many so I just will have to play this cymbal with destain I suppose.
