Hello, I decided to give one of my odd reels of 16mm colour film a clean with Filmguard that I had ordered from the states.

I used a small amount on some pec pads and wound the film through the folded pec pad. After a hundred feet or so I turned the pec pad around but however I noticed there was colour on the pad. Mainly blues and magentas.

My question is does Filmguard "strip" colour from the film and if not where did the blue and magenta come from?
Or is this normal?

The film stock says "Eastman 33 Safety Film".

I've attached a photo of said pad.

Thanks

I've used filmguard for years now but it's never striped any colours off, i have had the odd one or two second hand films where i little colour came away but i put it down to a very dirty print. A second clean resulted in no colour on the pad.

The reds remind me of red china marker residue I found on a print some years ago. If you inspect the film and it has no residue on it, and if you run the print through the cleaning cloth with Filmguard and you don't get anymore colors, I would not be concerned in the slightest.

I have had this happen too when using filmguard on a couple of prints.

I still find it a bit worrying though.

It also happened to me with Super-8-prints.
The tissue was blue and the material revealed greasy blue and red traces on the screen.
But the colours on the film itself didn’t change.

Could that be residues of a preceeding cleaner applied on the stock ?

Dominique that may be the reason but i then ask myself what if it is not the reason ? [Wink]

I've had some top-layer magenta rub off when using FilmGuard. That print had a tiny bit of heat damage, plus lots of showing wear, so the color on the cloth was no surprise. The solution is going to wash away anything not secured to the film base, which normally is a good thing. There's a LOT of color dye in your film if it's normal, and a little color on the cloth won't be a perceptible loss to the eye - by a long shot.

Bill thanks for that advice.

Is it not the case that if the film has oil on it that there is a greater chance that when cleaning and lubing with Filmguard that some colour dye may be removed too ?

David, I'm not knowledgeable of that scenario. What sort of oil are you referring to?

FilmGuard, FilmRenew, and Vitafilm do not leach dyes under any normal circumstance. In my experience.
