I know this has been debated before and I've looked up numerous articles but no one can seem to agree which is best. My entire collection has been cleaned and lubed with FilmGuard, which some articles say is useful for theaters but shouldn't be used for collections that will be viewed less and stored over long periods of time. Some sources say FilmRenew is a good product for warp and baggy films, but can cause "blotches" if not properly treated. I have a headache trying to figure out which is the best choice for me, so my first question is: are said "blotches" the same as putting on too much treatment that can be wiped off later or are these permanent? Will FilmRenew make my splice tape fall off? And finally, since they are different treatments with different ingredients (they're even different colors) will there be an issue if I ever have to use FilmRenew on a print that was once treated with FilmGuard? Thanks and time to take my meds!

Soaking a print in FilmRenew can cause tape splices to fail; normal cleaning will not. Blotches occur from improper drying. So you project the film after cleaning to utilize the heat of the projection lamp. If was applied heavily, then you use a dry cloth to remove excess. Lastly, FilmGuard leaves a slick coating on the print for a very long time. You would need to use a straight cleaner without lubricants first to remove it then apply FilmRenew. Remember, they both have their uses but while there is an overlap, they do not mix well unless applied appropriately. Always use only the amount that is necessary for results.

I have never used Filmguard,but can testify on the use of Filmrenew which is a VERY gentle film trearment.It does "exactly
what it says on the tin"to quote an advert over here,but it does
say in the guidelines that it can have an effect on tape splices and
plastic spools,so at least the manufacturer is letting you know.
Don't pay any attention to what the professionals use as they
have a different outlook on film to what you the collector has.
If you need proof of this I suggest you visit Bill Brandesteins'
excellent post on "35mm in Cinemas".Back to Filmrenew, even
if over applied won't harm your film,you can soak your film for weeks (which I have done) and no harm to film.

I've used both. I've never seen any problem with blotches from Filmrenew, nor had any problems with FilmGuard treated films that sit on the shelf for years. I've applied FilmGuard (which I prefer, because of its lubrication properties) to some of my older prints I had previously cleaned with Filmrenew and all went well. Never tried the reverse.

Hugh, what was the purpose of soaking for weeks, VS, curl? Has anyone had any luck using it to stop VS?

Bryan, neither cleaner will stop VS. Cleaning a print with it will remove accumulated acid. Soaking is to remove curl though results vary. Both have their uses as well as pure camphor.

Hello Bryan.the reason of soaking a short film was just to test the
claims that it was gentle to film,which I can say it is.Regarding
VS there are sachets you can place in with the film which are
supposed to alleviate the problem.

Hugh, just to clarify, the small molecular sieves of which you speak do not "cure" the VS they are merely designed to slow the process. but to reiterate what others have said both cleaners have there benefits and I too use both on different occasions.
