Photo-Flo is used to reduced water tension allowing water to run off film without leaving spots. It also helps the film dry more evenly. I would suggest contacting Kodak directly for advise on handling and cleaning damaged film. You could also try contacting an archivist at a local museum that specializes in photography.

After you use Kodak Photo-Flo 200 Solution (16 oz), you do squeegee the film.

Very concentrated, and if it is 1:200, that means you would add 5 ml of photo-flo to 1000 ml water or 1 liter water, if you prefer, or 2.5 ml to 500 ml water( 1/2 liter water).

The solution should be smooth if you follow the instructions listed on the bottle.

I am using it to recreate the mystery formula for the no-longer available Discwasher D4 fluid. According to online vinyl gurus: To 99% distilled water, 1% Isopropyl alcohol, add a single drop of Kodak Phot-Flo (as a wetting agent). For me, it works beautifully. My use is a couple drops on a brush. Can't speak to using large amounts in a record-cleaning machine, but I wouldn't hesitate. (btw the one large drop I added was to the D4 bottle, which is 1.25 oz.)

Very very long. Never seen one go bad

The recommended dilution is 1:200. The cap size cannot be measured.

This product is designed for use when processing Black and White Film only.
