Help!! How to clean my negatives?
I recently bought a second-hand Minolta Dimage Scan Dual III from a member here. I wanted to scan my old colour negatives and there is this bunch from my Europe trip 10 years ago which have a layer of something on them. On the scanned images, this layer looks like some spider-web threads.
Kindly refer to this link:

Close-up (top middle) with 'spider-web' layer:

I tried cleaning these negatives with PEC-12, Ethanol and Isopropanol but no avail (the layer still remains and no improvement). On one frame, I tried with water (!) and it did come off together with the emulsion. When I re-scan this frame (after water wash), the spider-webs gone from the scanned image, so it's water soluble.
Anyone has any experience in this? Any help is greatly appreciated!!
Thanks in advance,

Looks like a very bad case of fungus growth on the negative. The fungus has probably eaten into the emulsion, so it is hard to remove the marks without damaging the film further.
You can try looking at the Kodak white paper for fungus damage to prints and film at the following URL. Hope this is useful.

Looks like I got to keep my negatives better from now on.

i just store them in my dry box. every 6 months take them out and remove them from the plastic sleeve to make sure they do not stuck onto it. then place them back into the box again.
