Question: Do I have to remove with a lint free wipe after spraying on old slides?
Document: Certainly the supplier shipped promptly, but the product's usefulness is doubtful.This cleaner may be helpful on slides, but I doubt it. It may have removed stains or oil, so I use it only on slides which are worst off.But, on negatives it drew dust even when I used lint free squares.
I haven't tested it on any non-water marks that the manufacturer claims it works on, but I have no doubt that this stuff would do a fine job!Being in a spray bottle this was very easy to use - I sprayed some on and using a sterile lint-free gauze pad from my first aid kit wiped the negatives down.They scanned well, and I am very pleased with my purchase!
I have asthma, so I use it outdoors wearing a mask. Between the mask, the lint-free gloves to avoid getting fingerprints on the slide or print, the tweezers or wooden skewers to hold the slide to the prepared work surface, working outdoors, and the fear of doing more harm than good, this process is a little tense and difficult.But it is worth it. Anything that can possibly be rescued, has been rescued with this product.
If you plan to clean many photos, it may be best to go for the larger supply. To go along with this spray, buy thePEC-PAD Lint Free Wipes 4"x4" 100per/Pkg. Rizzo
on a scanner and risk contaminating successive images, so cleaning first is a must. (A good scanner glass cleaner is also a must. I recommend the Kinetronics Glass Cleaning Kit for Flatbed Scanners, also available at Amazon. )Cleaning is not a substitute for restoration work, but it does take you to a point at which you can begin restoration work. I use Pec Pads that are lint free 4"x 4" little pads.
Don't refresh the solution - take a new pad and spray it with a fresh amount or Pec-12 for each wipe.And don't use this for water-based stains. The only "solution" there is a complete water re-wash followed by careful, dust-free, low-temperature drying. If you don't know how to do this, seek professional help.

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.
I used this cleaner, per instructions, on some old Kodak Tri-X B&W film and it ruined them permanently. It left a sprinkling of white dots all over the emulsion. I followed the instructions to remove the dots, and it made it worse. I wrote the company about it twice, and got no reply. Luckily I stopped after a few negatives, but the ones it ruined were irreplaceable. I threw this crap out the next day.
For the amount I had to remove, I could clean 8 slides from one folded pad - 4 corners on one side, then flip it over and use the corners on the other side. You are absorbing plasticizer into the cloth with each cleaning, so it makes sense not to re-use the same part of the pad to clean successive slides. Before I reached that conclusion, I did see some light whitish streaking on some slides.
Be careful you don't use too much. That will leave a trace of cleaner on the slide. As i've read before, the best way to clean slides is to remove them from the mountings and then remount them in new mountings. However PEC 12 does do an excellent job if done properly.
Answer: Don't spray directly on slide; dampen wipe with cleaner and clean the slide with wipe.
