>>3123593Maybe if you'd have very dirty hands, idk. I also use my fingers (although I threw in a film squeegee with the order I just placed).
Some things to consider:
>Do you rinse long and thoroughly enough?It is essential that the water pushes through the whole developing tank, like in the shoddy MSPaint drawing I made. Use a hose connected to the hole or push a funnel in it. Don't just let it fall on top of the tank, because the bottom water will never be refreshed this way. You should rinse for at least 15 minutes and then do a final rinse.
>Maybe let the distilled water soak for a while during last rinse. It could be that your water is really hard (although I doubt that) and some CaCO3 remains in the filmOr what
>>3123599 says. Too much is never good. I believe just a drop of Photoflo is enough, but then again, I don't use it, I just use a drop of Dreft
