How To Clean Mouldy Slides
Вставка
- Опубліковано 1 сер 2014
- Those of us who have been travelling a lot before the time of digital cameras may have a huge collection of mouldy slides 10-20 years old. Some websites advise using alcohol to wipe off the mould. I have a better way. The wetting agent in these wipes provides just the right amount of lubrication to clean off the mould in slides without scratching the film too much.

Great! Thank you very much. We work with slides and was looking for the way to clean this.
Thanks, I just acquired about 100 slides from an abandoned building while on a photo shoot inside, im looking to clean them up as best I can to view. This helped a lot
see my comments above!

Thank you! I have a working slide projector and was afraid to clean slides from the 50's. You answered my question.
Clean them, but not by the method suggested in this video.
@@andreibeldean9345 Why not?

Most if not all the mould was on the soft emulsion side, so you have to wipe softly and quickly before the emulsion softens. If you then wipe with a lint-free cloth to remove all the wet wipe fibres stuck in the emulsion you can feel the cloth drag on the soft emulsion.
Let the slide dry and harden for a few minutes then hold the slide at a flat angle to a bright light and you can see the lint stuck to the emulsion and the non-emulsion side. The emulsion side of a Kodachrome slide is the side with the Kodak label.
You can then use the lint-free cloth to wipe or flip the fluff and fibres off.
You can see the fires change direction as you wipe. This can be done firmly and several times on the viewing side but be gentle on the other side, the emulsion side.
Before scanning, I use a soft makeup brush to remove any remaining dust and fibres, especially from an old Kodak cardboard mount.
But the important point is that wet wipes have water content, and any kind of water on a slide, especially the emulsion, will ruin the slide. Isopropyl alcohol on the other hand has virtually no water content and evaporates almost immediately, preserving the slide. Absolutely no conservationist or archivist would recommend using any kind of water based solution to clean a slide!

Interesting. Thanks! I've just bought a scanner and the mould and fingerprints are very noticeable.
I can recommend you to get a lint free gloves or disposable non-sterile and powderless gloves for prevent fingerprints.
A slid projector is a fantastic way to show family photos when your all together on a white wall or a projection screen. Old technology is the best, Thanks for the cleaning tips. Kind regards Simon.
Ya, it seemed kind of laughable at one point in time, the classic cliche of your parents friends dreading that they would break out the projector to show vacation photos. But it really is pretty cool, to see such a huge image brightly projected of your great memories. At that size it's almost like you are really there, rather than your friends showing you their recent adventures on an iphone.
I'd love to get my projector out a lot more but gosh, bulbs are expensive!
@@augustopinochet2495 I have a spare Halogen bulb for my Leitz Prodolux Projetor.
will any wet wipe work or are there some ingredients to avoid?
Mold spores remain on the slide mount. Use a new slide mount!
Thanks!
What type of wet wipe? where do you get these?
see above!
Thanks! I'm gonna try in the summer at my mom's. And yes we have a working projector :D
how would the mould get there in the first place?
oh so that's how it happens... what does the mould even eat?
the dyes maybe? weird diet.
how are you gonna take care of your slides then?
The film emulsion uses gelatin as a binding agent.
ahhh! thanks for explaining :-)
The mould spores are in the air, keep them stored DRY in Canberra NOT Sydney or New Guinea
Doesn't work so well with old Kodachrome cardboard mounts.
I did not remove the mount, they did improve see Flickr user spelio , slides scan cleaning
Wouldn't you be better off completely immersing the slide, considering you don't have cardboard frames? Then less chance of all the scratches you just put on the slide.
The mould still needs a few wipes, see my new comment above..
or use tetenal graphic arts cleaner
DON'T USE WATER OR ALCOHOL -- use professional 12 slide cleaner. It's only $10.
99% alcohol is fine. In fact it was Kodak's recommendation when suddenly carbon tetrachloride based film cleaners were removed from the market in the mid 1990 under the Montreal accord. Alcohol isn't as volatile as dedicated film cleaners so you have to allow for a little more dry time. My company since the mid 1990 still only uses alcohol as a film cleaner. There are carcinogens in many dedicated film cleaners even still and there's no way for myself or my staff , I would want to subject them to long term exposure to the stuff when simple safe cheap alcohol, with proper handling, does a perfectly fine job. Even the film cleaners such as Pec 12 claim to be non-carcinogenic are stinky with a strong solvent smell and not pleasant to work with over long periods of time even in a well ventilated area. Fine for people doing occasional film cleaning.

Extremly bad advice. What you will aquire by this method is ruining your slides.
Ugh...this is a terrible idea. Film emulsions are water soluble and mold makes the emulsion even further water soluble. With quick contact to the emulsion side of the film, you'll likely get away without damaging the emulsion with a water based wipe but it doesn't take long at all for the emulsion to become soft and then it is very easily damaged. Because it becomes soft you also run the risk of dust sinking permanently into the soft gelatin emulsion, never to be removed. Also, there's a plethra of chemicals not necessary film friendly in these wipes including scents. While I do believe that you could get away with this method as long as you were very quick and the slided didn't really have emulsion side mold - it really isn't good advice at all. Sorry Chan Joon Yee but this approach would never be endorsed by archivists or conservationist.

What should we use to clean them then? (Have a historical slide from June 1954)
This is terrible advice. If you want to ruin your negatives forever, use water or alcohol. If you want to clean them use pec 12 film cleaner. It won't ruin the film emulsion. It's only 8$. You need only a drop.
Alcohol will not ruin your negatives forever. It was the recommended and accepted film cleaner in the 90s when regulation ended the sale of carbon tetrachloride film cleaners which were the standard at the time. On the recommendation of Kodak Professional our company switched to 99.9% alcohol then and have never looked back even as new more volatile film cleaners came into the market. With alcohol you simply have to accept a longer drying time and film lubricant won't dissolve in it properly. btw...pec 12 removes the varnish from 40s through 50s Kodachromes so you need to be careful with that stuff in some cases. That will make a mess of precious old Kodachromes.
This is terrible advice for one reason. People will go out and buy alcohol. It will contain water. They'll forget about the 99.9 pure grade and just remember some video on the internet said to use alcohol and buy the cheaper 91% or 71% and not even notice even if they intended on buying the right stuff. Or even having the 99% pure they'll grab the wrong bottle on the shelf and use that by mistake. Believe me. I worked supporting a technical product and you wouldn't believe the stupid careless things people did. If all they sold was 99.9% pure alcohol then sure. Most places don't even stock 99.9% stuff. People will pick up whatever is available and call it a day. I absolutely, positively, guarantee this. No. Bad. Buy regular film cleaner. It isn't that expensive. Follow the directions. People cleaning 70 or 80 year old film likely know what they are doing or will research the film and use the right stuff as recommended by the manufacturer. Seasoned photographers will not watch this video because they already know how to clean film. This video will only attract new people who might not even have ever used film who want to scan something but not really know what they are doing. There are certain types of film that will be ruined using any type of cleaner. They will not know this. (Polachrome is one)
