Advice? Care and feeding of very old celluloid picture knife!

[Two Dog Man]

Howdy All,

I came across a pair of very old Wabash picture knives with what turns out to be celluloid scales. They are both quite small, two blade pen knives. One is already badly deteriorated but this one still has a visible recognizable image. I have been told to be careful about storage with other knives, but I also haven't cleaned them up yet and I was wondering if there is anything I should know before I go to that task. Here's a shot of the best of the two:

Any advice would be wonderful!

I asked about celluloid scales a while back and got some helpful replies: http://www.bladeforums.com/forums/s...elluloid-Scales-How-Old-To-Have-the-Negatives. The article that JAB cited is excellent.
