I have a view films where the audio tracks make my projector really dirty with the brown powder.
Is there something I can do to keep the machine clean, or make the film not lose his audio track powder?

Cheers

Cleaning the films (with a product like Filmguard)will help but I'm afraid you still will have to clean your projector from time to time with alcohol.

Project only laminated stripe NOT pasted and that will cut your problems to a minimum and get rid of 90% of the contamination.

So I guess that these are pasted ones.
Bummer.

If you seeing an abnormal amount of residue Koen,chances are it will be a later Polyester pasted print.
These are very abrasive on both the film path and worse still, the sound heads.

Be careful not to expose too many "lumpy" pasted striped prints to your lovely new Bauer. It can and will, over time, completely ruin your sound heads.

Laminated prints, treated with filmguard are absolutely fine, but if the paste stripe feels "lumpy" and uneven in texture be very careful not to project often and a thorough clean of the entire path will be required on each and every occasion you project these prints.

Also the sound from pasted striped prints will often be far inferior to your laminated ones.

Is there something I can do to prevent the pasted ones from spreading the brown paste?
In the art-world you can use hairspray as a fixing layer for chalk drawings (not that this would be good for film) but is there something like it?

I've seen a lot of oxide shedding on older Walton prints for some reason.

A clean with Filmguard will remove a lot of excess, followed by a dry cloth clean also. It won't cure the problem completely, so cleaning the film path and gate is a must, but it should prevent any major clogging.

I have to say in my experience, prints which shed a lot of oxide are less common; so that's the good news! [Smile]

But I'd clean any print before projecting it as a matter of course.

Time consuming, but part of the hobby!! [Wink]

Thanks,
I'll keep it to the cleaning before and after projecting the film. (or maybe after very reel)
