Moldy Leather handle

Oct 9, 2005
I could use some help here guys.

My grandfathers KaBar he carried in WWII has been in my collection for some years now, but suddenly it has developed some fuzzy white mold on the leather handle. I can't say for certain how long it has been going on as this knife is not a user for me, I probably only handle it a couple times a year when I think of the old man.
It is stored in the same dry closet as my other knives, some of which have leather handles and/or sheaths which are unaffected by this. :confused:

What is the best way to take care of this?

Wipe it off if possible with a rag. If that don't work, a paper towel with rubbing alchohol should take care of it. Put some leather conditioner on it. Also I have noticed that neatsfoot oil has a tendency that after sitting a while it will form a white fuzzy mold also, especially on my boots. He could have applied some at one point which would explain why only that one has it.
