Google for more info as I haven't done film processing since 2008 when my wife and I closed our Manhattan, NY custom lab business.ĭepending on the film scanner and software used, artifacts such as dust, hair, etc might not be eliminated. A C-41 or E-6 Stabilizer which contains Formaldehyde is used with each respective film as a final bath. However, Kodak color negative and Ektachrome films were processed at higher temperatures so a rewash could be done at a higher temperature as well. Finish your water baths with a final one with the correct amount of Kodak Photo-flo or someone else's brand. Use 68 degree water or very close to that temperature (more critical) so as not to reticulate the emulsion which might increase the size of the film grain or worse. Just bathe your B/W negatives in batches of clean, still water for 5 to 10 minutes (not critical).
A pin might work better than anything larger, but do take care at this stage as you might have more problems than you have already. Hanging single or strips of negs up to dry can be quite tricky as water marks can be left if water runs from any thing suspending the negs. I would suggest placing them carefully in a tray of water (with wetting agent) somewhere around 15 to 20 centigrade (You don't want to introduce reticulation) and very gently rubbing them with the tip of your finger, whilst the negs are submerged. I don't think however washing them in running water will remove any ingrained dust/dirt. If you haven't got Photoflo the smallest spot of washing up liquid will do the trick. With care there should be no problem in rewashing your negatives. Is there any reason I couldn't whip up a batch of photoflo, or what ever the wetting agent you used to use as the last step of development, and rewash the negs? Can you think of any harm this might cause? Was it the same solution for B&W ands color? Mainly dust, but I cannot seem to get rid of it all with brushing/blowing.
In scanning my old concert negatives (40 years), I see that some of my negative strips are not as clean as I would like.
