Chris;

You can use a Kodak or Fuji Final Rinse or Stabilzer at virtually any temperature from 68 - 102 deg F, as long as the film is not subjected to a sudden change in temperature. All equipment used should be washed with very hot water after use though. Don't wash in cold water.

I really don't know about other products. They probably use different chemistry as the Kodak and Fuji stuff is proprietary.
