Cleaning Kodachrome slides?
I have some 1940's vintage Kodachrome color slides that I want to
clean, re-mount in Gepe mounts, and scan. Any recommendations on how to clean them safely? I tested one today in some warm water and Kodak Fotoflow. The emulsion appeared to bubble up, which made me nervous. It settled down again after drying, but the light areas (sky) look a bit "crazed." It may have already looked that way, I need to take a close look at some of the others. Thanks -Mark |

Kodak did, but I can't find it anymore. It was a good product. However, there are several similar products. Delta, Edwal, et al have them. I have used "Pec-12", for instance. Cheers. |

I also read a recommendation for a Kodak product called E-6 Final Rinse. Does anyone here have experience with that as a product for cleaning negatives? Thanks -Mark |

It's an extremely volatile cleaner, which means that your slides are dry and ready to work with in mere seconds. And because there's no swelling, there's less risk of physical damage. |

That may be what you raised when you wet the slide. I do not remember how to remove it. Michael |

It may have already looked that way, I need to take a close look at some of the others. Thanks -Mark 1940's and 1950's Kodachrome film was coated with either of two types of lacquer. The older one was soluble in a 5% sodium carbonate solution or in stock Dektol developer. The other was soluble in Carbon Tetrachloride, which was Kodak's recommeded film cleaner at the time. Kodak recommended that the film be tested with Carbon Tet first. If the laquer came off the cleaner could then be used to remove it all. The alkaline bath will cause the solvent type laquer to swell and craze, possibly damaging the underlying emulsion. In either case the film should be washed after removing the lacquer. At the time Kodak made a lacquer for replacing the original. I have no idea of what to use now. In place of Carbon tet I would suggest 99% Isopropyl alcohol, which is Kodak's currently recommended film cleaner. A brief test will show if it works on the lacquer. Carbon tetrachloride, once a very common solvent and cleaning fluid, proved to be very toxic and also an environmental hazard. Even if it were easily available(which it isn't) I would strongly recommend staying away from it. You may possibly be able to get more information from Kodak. Their customer service number in the US is toll free 1 800 242 2424, ask for extension 19 (professional service). -- --- Richard Knoppow Los Angeles, CA, USA |

It yellows over time. And I should have mentioned that the lacquer is sometimes attacked by mold where the humidity is high. |
