I just downloaded "Processing B&W Paper" pdf from the Ilford site and noticed a possible discrepancy. On page 3, top left, it says to wash for 20 minutes.
But then further down the page under the "optimim pernance sequence", it says to wash for 5 minutes.
Both times are mentioned after using their washaid.
Five minutes sounds awfully short. So is 20 minutes the correct time?
