Besides, How long does it take to get Hypoclear?
Although Kodak says you can use Hypo Clear and then wash for only five minutes, washing a bit longer will not do any damage. Your final soak in distilled water to get rid of the tap water minerals can simply be extended to a few minutes and give you an extra bit of wash.
Keeping this in mind, What can I use instead of photo Flo? Photo-flo is just a basic wetting agent (or nonionic surfactant if we’re being fancy).

You should use it as a final rinse before you hang your film up to dry. It will allow the film to dry in a more uniform fashion and thus prevent the marks. After development, stop, fix and wash, you simply leave your film in the wetting agent for about a minute.
What is chemical wetting?
wetting agent, also called surfactant, chemical substance that increases the spreading and penetrating properties of a liquid by lowering its surface tension—that is, the tendency of its molecules to adhere to each other.

White distilled vinegar, the stuff you buy in the US is usually 5% but in other countries the concentration can be higher. Use it at 1.5-2% for prints and use a plain water stop bath for film. As others have said the savings are pretty small but in a pinch I have used it. It works very well.
What is the process of developing photos?

What is photo wetting agent?
Wetting-agent is a very strong but pure detergent. Its purpose is to break the surface tension of the water and allow it to run off the surface of the film without hanging in drops. Drops of water hanging on the film will cause horseshoe-shaped water marks which cannot be removed.
