Interesting tip. Thanks for sharing. A couple of useful bits of information about Kodak PhotoFlo. It is used heavily in the film industry. Many major motion pictures are still being shot on Kodak film. A good example is the new Star Wars movie that will be released this year. If the photography suppliers stop carrying it, you may be able to pick it up at a motion picture supply company. The two main ingredients in PhotoFlo are (by weight): 35-40% Ethylene glycol 25-30% p-tert-octylphenoxy polyethoxy ethyl alcohol (Note, the above is the most concentrated kind. The less concentrated kind add more water.) Ethylene glycol is essentially anti-freeze. You should dispose of it just like you would normal anti-freeze. Doubly so if you get the high-concentration variety. I suspect most of the 'magic' is coming from the p-tert-octylphenoxy polyethoxy ethyl alcohol. This is a very powerful and (in this case) highly concentrated surfactant. Various forms of it are used when you need to get something _really_ clean. It is used in industrial cleaning at these concentrations. It is probably a good idea to avoid drinking any. ;-) Oh... if you have a dog (or any pet) be sure they can't get in to this stuff or lap it up if you accidentally spill some. -Ryan On Thu, January 1, 2015 23:46, Richard Tenney via UVAA wrote:
Someone recently posted the following in the Criterion Dynascope email forum re: mirror cleaning, that I thought some of you might find useful/interesting. Â I had never heard of this stuff (and it's probably overkill, but what the heck)... "The best possible soap is Kodak PhotoFlo, which was designed as a last rinse for photographic film. Â It is the essence of all dish soaps, minus anything else. Â Still available from B&H and Adorama. Â Useful anytime you want to avoid water spots, like clear shower panels. Â It has to be diluted in distilled water 200:1 so a pint goes forever."
