......I have always squeegeed my film with a pre-moistened sponge squeegee (Yankee)after using Photo-Flo for 2 minutes. I have yet (40 years) to get any scratches from the sponge. I do soak the sponge squeegee for 10-15 minutes first....... I do use a hardening fixer. My film dries faster and cleaner.
Exactly my procedure. Let the sponge touch very lightly the film.
