Rollei RWA Wetting Agent is a wetting agent for films and papers. RWA Wetting Agent reduces drying time and aids uniform drying. RWA Wetting Agent has a fungicidal and antistatic effect. Dilution is 1+100 or a very small capfull in a tray to dip and dunk the film.
The Brownie Camera Guy says:
Using a wetting agent is mandatory in my darkroom. I also suggest never using a squeegee on film. Let it drip dry after treatment.
