PEC-12 Photographic Emulsion Cleaner - Remove Non-Water Based Stains, Grease & Ink from Emulsions and Bases - for Cleaning 35mm Film, Photo Negative, B&W Slide with Dropper Tip (2oz) 2-Pack

I'm in the process of scanning more than a thousand Kodachrome slides (some 60 years old) and a huge quantity of photographs and negatives. Some of the photographs have been handled well, others not so well and are extremely dirty. With the Photographic Emulsion cleaner I've been able to remove spots, mold, even the dirt from 50 year old fingerprints. It's worked near miracles. There are some flaws that won't go away, the instructions clearly state that if the product doesn't work the first time, don't try a second, it can't remove every spot and repeated use may damage the emulsion. Certain emulsions will not tolerate the cleaner, a test procedure is outlined on the bottle. The cleaner has an extremely potent odor. If you're doing more than one or two photographs you need to get away from your work area to use it-leaving a window cracked open isn't a bad idea. It doesn't take much, just a little squirt on a cloth, don't use it at all unless a photograph needs it. It looks like this one container may see me through the entire project.

Ordered these after finishing up the single bottle I originally bought. Works great for cleaning decades old 35mm slides. Beware of fumes.

It's been great on our slides. Works as it's stated to work. No complaints. It's a great product. What more can I say?

On my first order this came in and was spilled out into the box. The company did right by me and replaced the product for me. I in return bought several more containers from them, because this is the type of company that I like, ones who do right by their clients. This is great for cleaning pictures (always test first) and for cleaning old negatives up. It works and it amazing. I would suggest using in a well ventilated room if the strong odor bothers you.

hello, i needed a good quality cleaner for some very old color slides, before i scan them to my hard drive from the scanner. this product works as defined, but has a strong odor that reminds me of the old spirit duplicator (also referred to as a Ditto machine in the US). when the newly filled fluid was installed in the ditto machine and the first few copies were run off, it gave an unusual smell that lingered all day. this Photographic Emulsion Cleaner has that smell. use in a well ventilated area and not near heat sources. it does its job, but i think i will find another less smelly product to do the job. if you can stand the odor, it does a great job on the cleaning end. but....

The product is fine but the driver keeps delivering to motorhome instead of the house!

I understand some of the reviewers saying the product has a vapor, but that goes along with the territory. This is not water, it is a special chemical designed to evaporate quickly. I used the product outside and also in a bathroom I don't usually use and I had the window open to give ventilation. That worked to help dissipate the vapors. The PEC removed some residue on several very poor condition negatives and I was able to clean them and scan them and get a much cleaner result. I just used a tiny amount and I agree with other posters that this bottle will last a LONG time. When the package arrived, I knew exactly what it was because I could smell the vapor coming from the packaging. If you need to clean oil based residue from negatives or slides this will do the trick.

There was an autograph in gold pen on the man on the right. This stuff got it completely off without a trace left behind and no damage!

J'utilise PEC-12 depuis un an pour nettoyer les films 8 mm et Super 8 de mes clients avant leur numérisation. Il nettoie très bien, enlève les graisses et la poussière accumulée sur les pellicules et en plus, pour moi, est sa rapidité à sécher très rapidement (ce qui augment de très beaucoup ma production) sans laisser de résidus. Je le recommande fortement. J'adore ce produit.

Pec 12 is very useful at certain applications. In my view its performance as an emulsion cleaner is limited to use on current 35mm colour film and even then you risk damaging the negative. On older film where the chemical composition of the emulsion may have shifted caution is highly recommended. I would be very wary of using it on any slide film emulsion and certainly never use it on Kodachrome emulsion. If in doubt only apply on the smooth base side of the film. Its better to have a print with with some flaws or a scan you can alter in photoshop than a destroyed negative. I have used it on the base side of 1960s film to remove marks left by condensation on glass mounted slides and it performed very well. Using a Giottos GTAA1900 Rocket Air Blower - Black then a Matin M-6328 Small Size Goat Hair Dust Brush to remove any loose debris is important. Then spray some of the pec 12 on Photographic Solutions 10x10cm Pec Pad (Pack of 100) as the final part of the cleaning routine. Use sparingly or it will leave a residue. It is very strong so don't plan to clean a large amount in one go and keep the area well ventilated.

Cleans finger prints and non-water based stains as advertised. Too bad many dirt spots on old negatives are water based!

I thought I reviewed this last time I purchased one, it arrived within dates stated, and it cleans photo and film, but needs care on old photos as they are not fixed the same, not cheap but works as claimed

This is fantastic for all Kodak slides. Very happy customers in that department. Also very useful for cleaning sticker residue that may get left behind on stuff. Probably also good for cleaning other things but I'll have to experiment and let you all know what they are!
