Cleaning old 4x5 neg

[Rhodes]

Found a old 4x5 neg, from kodak, the notche code I can not identify, probably Kodalith Pan 2568 (it is the more like), but after scanning I can post here.
I want5 to now the best way to clean. Should I wash in destiled water and dry. Distiled water plus something or just try to clean with a dust blower?

Depends on how it is dirty - if just dusty, a dust blower should take most of it. If it is greasy, it might need more. A good wash in 1L of distilled water with a capful of both photoflow and 99% isopropyl alcohol (not the 70% which has mineral oil in it!) will dry nicely. If you need more, I have used a new microfiber cloth in distilled water and rubbed very gently.

Besides dus, a few spots of rust (I think) and wood dust. The neg was inside a envolope but it was in a box full of old stamps and pressure plates.

Good Evening, Rhodes,

As a philatelist, I caution you NOT to discard the old stamps. Chances are they will be of very nominal value, but one never knows . . .

I know, my grandfather was also one and collected!
The stamps (not the mail ones, postmark, seal, imprint, ) and impresses remain in the box that was stored in a new place, since they may be going to a museum.
