firstly, old negs are very fragile, the emulsion wasn't hardened, so avoid
anything above 20-22C. You can clean the glass side, as long as it doesn't
affect the emulsion. I wouldn't try anything more than water and cloth.
Even then, I would make a contact print, just in case. Saying that, if you
do it using soft light source, you may need less time for removal of
scratches and dirt. You may wet the whole lot in water plus surfactant
(PhotoFlo) and dry to remove any drying marks. However, it may not work.

stay away from anything but water, if it does affect the emulsion.

contact printing can be done at any location. use paper on the softer side,
so you get the whole image, even if it is soft, it can be improved in PS.
BTW, don't forget to put emulsion to emulsion. I know, you know, just a
reminder. :-{)
I am currently struggling with BW negs 35 mm, scanning is nothing, but
cleaning afterwards is a real PIA. ICE doesn't work.
