If this is about clearing iron, what is wrong with the method that people
have been using for the last 140 years, i.e. clearing in 1% HcL ?
I have EDTA toned prints the result of a swap with an expert, that after 15
years have now turned an unpleasant shade of brown.Not very stable, Loris.
Delving into the kind of detaii there has been in this thread is really
