Hi, first of all I would like to a big thanks to those out there who helped me with my Elmo problems and a special thanks to Kevin. I'm pretty sure its the belt and have got two on their way, that's right I’m so impressed with the Elmo I bought another one. So I’m ready for any belt problems.
Now I’ve got a very nice print of "OH MR PORTER" it came in a tin wound on two 1200ft Elmo reels. It cost me £58.00 on eBay and I think it was a bargain, as the reels are worth £12.00 each and the film is perfect. It had new print 1978 written on the back of the tin, and I’m sure it's only had one screening, not a mark. In any case should I clean it, and how. Oh and it has a picture that must have been taken from the original box it came in, is there any way of telling who made the print?
Thanks again to all you cin'e nuts.

I personally don't think you should put any chemicals on film unless they're needed. A simple slow rewind on a bench thru a velvet will remove surface dust and dirt without subjecting the film to any chemicals.

Others disagree and especially 16mm collectors have developed a habit of soaking their films in chemicals.

Dust and dirt are the main causes of wear and scratches. Although mine is a minority view, I clean film with propan-2-ol (isopropyl alcohol in old money) only when necessary and don't lubricate. However, all projectors are cleaned thoroughly and often (alcohol). All rubbing surfaces are then treated with spray polish. AFTER EVERY SESSION!

I agree with John -- I only clean prints that badly need to be cleaned -- otherwise, leave them alone.......

Tim,

Why do you not lubricate the films? Is it a general concern about the reaction of film lubricants with dyes in the emulsion? Do you have any evidence that supports your view?

Just interested, I am NOT challenging your view!

What an interesting topic. I do clean my films with Cresclean and find that even new prints seem to run through the Elmo's much smoother and with a steadier frame line. I also think that it helps to make the mag stripe surface a little less aggressive on those delicate sound heads which are now getting harder to come by.
I think there are schools of thought for both using and not using these cleaners/lubricants and I'm one for using them. [Smile]

I do however think there is evidence in my own collection that 2.22, which is no longer available, did speed up the dreaded fade on some of my Eastman prints. [Frown]

Tim,

Tony,

Firstly, I'm lubricating the projector film path. Those spray polishes are really very hard wearing. (I'd use a silicone lubricant, but when you ask about long-term safety with plastics, the manufacturers get very coy.) Secondly, I feel that anything applied to a film that may make it to any extent sticky is likely to hold onto dirt or grit.

It is amazing how much dirt builds up, especially in the gate, even when running clean films through them. Dual gauge Eumigs with removable gate assemblies are easy to clean. For the others - than goodness for cotton buds!

Derek Simmonds would often remind customers to treat new films before projecting to avoid stuttering and wow. I believe the term he used was that new films were 'green' and needed lubrication.
Chris, with regard to 'Oh Mr. Porter' Walton released a 4x400 version that fitted two 800ft spools. DCR released the film full-length at 5x400ft so you may have the complete version.
A few years back Derann re-released the film in its full version using the DCR negative but that was, I think, in the early 1990's
I have the Walton version in its original boxes and the label clearly states 'WALTON'

I'm in agreement with Kevin. I use FilmGuard to clean & lubricate my prints, especially the ones I've gotten from eBay. At the very least one should use John's method on a newly acquired print. Never thread up a print without checking it first. Ask D'Arcy to tell his "staple edit" story......

Kev,

Like you I have found Cresclean very effective at hiding lines. But how can we be sure it is inert when it comes to film emulsions? I had not given that much thought? Will Classic face law suits from us in 10 yrs? Oh, sorry s8 won't be around then (joke!).

BTW is it just me or have ebay film sales slowed?

Hello,

as I am buying used super8mm features mostly, I must say that I prefer them not to be treated by any film cleaner. I have received several prints that have been treated with film cleaner and if you look at the prints closely you will notice many residues of the fluid on the prints that look like small puddles. Sometimes these residues can even be seen during projection.

Best Wishes
