I've never used washaid and as I said in my first post I've never had a film go off on me since I started using the Ilford method.

I don't let my films sit in between changes of water, as far as I'm concerned it's just a waste of time that prolongs the process that I hate most in my photography.

The method I posted is my own modification. I'm a former accountant who believes nothing that anyone says and have an unhealthy paranoia about making sure that my films are archival. I was told by a photographer at the beginning of my interest in photography to put a "slurp" of dilute hydrogen peroxide in the developing tank with the first water rinse after the film had been fixed to speed up the washing to a couple of minutes. Needless to say a few months later my films began to stain and were ruined. I learned a hard but good lesson with that experience.
