Digital BW, The Print

I JUST ran across a VERY important 2-neg strip of 6x6 Tri-X taken in 1972.

Although it is in a sleeve (and not stuck to it, thank you!) I notice a patch of mold about the size of a dime near one edge of one frame. The other has wrinkles, but I can deal with that.

What is the best way to remove--or at least minimize-- the mold so I can get a fairly decent scan.

It is something I shot of Johnny Cash and June Carter Cash backstage, that is why it is important.

I want to try the least destructive first.

Thanks to anyone with experience in this.
