What is the best method to remove Filmguard from a print? Will it just wipe off, or perhaps will isopropyl alcohol help?

Maurice, be very care full when using isopropyl alcohol or any chemicals that evaporate quickly, as it cause's film shrinkage and warping

Not to mention possibly taking off some sound stripe.

Maurice, have to ask why you need to remove it? Is there too much on the print?

If so, a few runs through a dry 100% cotton handkerchief should remove the excess. I've never had any ill effects from Filmguard except when too much has been applied.

If a film print has too much cleaning chemical on it then the lesson learned here is the proper way to apply the chemical is through a slow-moving cleaner machine seconds before the film enters the projector gate

A soaked rag Between handcrank rewinds is not the way to apply the chemical

If that's correct, I have doing it wrong forever, without any bad experiences so far [Cool]

me as well, i did learn years ago not to over apply, if i feel too much is on i simply rewind again using a clean dry 10% cotton handkerchief, it works perfect and has done all my life in cine. 40 Years.
Obviously the ideal way is to use a proper cleaning machine add on to the projector, but there was no way i was paying some of the prices that were asked of these cleaning machines. Some of them were twice the price as a decent projector. [Wink]

I use the same method as Tom and have done for around 25 years now with nothing but great results.

But Filmguard especially has to applied very sparingly. Certainly would never use a soaked rag Chip! [Smile]

The film cleaner machines are easy to find if the price is right. The Kelmar unit for 35mm can easily be modified from 35mm down to 8/16. All you do is remove and swap some parts then reinstall them. Building a holder to your machine could take some trial and error. But once configured, they are the best way to do this.

What scares me with the rag is scratching of film. The cleaners work on the basis of motion. The projector pulls the film, the film moves a main guide roller, and worm gears rotate the cotton cleaning rolls. Everything moves with the film - so scratching is avoided.

If you can consider the application vs the cost, it is a wise decision to do so. The film cleaners can be expensive, like a machine or a film print. But for the principle of insurance, it can't be beat.

Like many others, I spray a small amount of FilmGuard on a cut piece of lint free cloth, fold that in half and apply it to both sides while turning rewinds at a slow speed. I replace the cloth when it looks necessary. This has done the job for years & years.

I use the Film-O-Clean for wet gate projection and also during CineSea when I'm given a film to project that hasn't been cleaned. However, I prefer to clean by hand because I can feel if there's any sprocket damage, burnt frames or bad splices.

I can definatly see the benefits Chip. 100%.
It's just a matter of cost more than anything. When using the basic handkerchief method, the thing to remember to avoid scratching are simple, always use a 100% hanky, (or similar).
Each time you re-apply the cleaner, (for me it tends to be a very small amount every 150/200ft) use a different part of the cloth,
at the end, rewind through another clean part of the cloth but no pressure, this takes off the excess perfectly.
A few second hand films have made the cloth unbelievably filthy, if this happens it gets second application right away, this usually does the trick, fortunately, its rare. [Wink]

I am not asking how to apply Filmguard, but how to remove it from a film.

Maurice,

Sorry to get off topic. If too much FilmGuard has been applied, I would use my same method for cleaning, only using a dry cloth wrapped around the film lightly, replaced every 100' or so.

Well, like I also said Maurice.

But why? Too much on the print?

Maurice, if you just want to remove an excess of Filmguard, a piece of cloth will be enough but if you want to remove it completely, it will not work. I remember the message of a member who had sent a film to a lab to add a soundtrack. In this case, it was said that it takes about one year for the product to evaporate completely.

Nobody got off topic what I was trying to say is when you apply film guard to the cotton rolls of the cleaner machine over time it is absorbed by the cotton rolls which avoids a print from being soaked.

And Doug, I will normally do film inspection first, then do a cleaning as a 2nd step. It’s never extra work- it is always for the love of film!

However we clean our films, I think we all here agree on that Chip. [Smile]

Is it OK to use an old cotton t-shirt cut into pieces for applying and then removing excess of the Filmguard?
I have specific cloths bought in laboratories, in polyester, microfiber, rough, etc., but if it is necessary to change cloth often it is not appropriate to use those.

I use that, Luigi (pieces of cotton from t shirts or blankets). Some films are incredibly dirtyand sometimes to change the cloth quiete often.

Thanks, Dom. And you also know how much time must pass to be able to project the film after cleaning?

You can project the film immediately after having removed the excess of Filmguard. As I reported it before, the only films that tend to hold some drops on some sections are optical super 8 (not other gauges). I have no Idea why but extra attention is needed for those films.

Oh, what a strange thing! But the drops only on the path of the optical track or even on the image space?
