Originally posted by ericp I've been told that you can also use Photo-flo, mixed with distilled water, to clean old negatives and slides. I haven't done it myself, but it sounds workable, and loads cheaper than PEC-12.
Using distilled water with a surfactant like Photo-flo is not too different from using water, which is likely a fatal exercise unless you're running your negs through a WATER BATH of a distilled water, Photo-flo combo. (Which is still an exercise fret with DANGER unless you know what the hell you're doing.)
Here's prime example that a little knowledge is a dangerous thing. To just quote someone else's advice without elaborating or thinking through how stuff works can lead to horrific outcomes. I can't imagine the amounts of precious negs that someone who takes up this advice naively will lose.
For the original poster, Big Yellow's current recommendation is to use 100% ethyl alcohol (don't substitute it with the stuff you get at the pharmacy - there's water in the alcohol you buy there. Water is your worse enemy for this task). Dig around the Kodak website and you should find the relevant pub.
PEC12 is well worth the money. Do not rub the Pecpads hard on your media. They can still scratch that way.
Dear friend, PEC 12 is a bottle of liquid specially made to remove oil based stains from photographical film and similar materials. You don't have to rub the surface. It is supposed to dissolve the stain with just one light wipe from a cotton bud. READ THE INSTRUCTIONS CAREFULLY BEFORE USE !!!!!! :bsmilie:

Yes Jason, I know what Pec12 is and how it should be used, I have been using it for the last 8 years. And yes, there are people who do not read instructions, unlike yourself. I have had friends complain to me that using Pec12 scratches their negs until I find out that they actually press down hard when they can't get tougher dirt out.
I had the same problem with moldy slides, and was searching for ways of dealing with it, and this seemed to be one approach ... I checked with the people at Cathay Photo (the professional side) and they said that it should not harm the slides, but to be careful and test first every time, as the precious slides are irreplaceable.
That's why I put in the caveats in my post ... to test first. At first sign of trouble, you stop ...
BTW, to answer Gambler's original question further, I did try other ways, some of them bordering on the ridiculous, to see which is the best way. One method involved white glue, another needed duct tape ... :bsmilie: ... needless to say, 99% of the attempts didn't work, but I had fun trying ... bit of a twisted cerebral exercise ...
