Hi,
Mention has been made that, for washing, the water should
be "acidified" or rendered more alkaline. What are
suitable substances that can be used. Could I use Baking
soda to render the water more alkaline......? or "acidify"
by adding vinegar or do I have to use Acetic Acid 28%.
Are there household chemicals that can be used?
Also, persons say that the water should be acidified or
rendered more alkaline, but by how much? No specific
measurements are given. Hard to know how to proceed if
you've never done it before. Would it be possible, in the
future, to be more precise than just stating that water
should be acidified or what ever????? These are
non-quantifiable statements and not very useful to me. My
highschool Chemistry teacher would have failed me if I had
handed in a lab report saying that I added "a bit more
acid" to the solution. He would have wanted a precise
measurable quantity. Would it be possible to ask for the
same here, please!
Cheers,
Bogdan
The old books suggest a "few drops" of Acetic acid in
the wash water. I think you have to wash by successive baths
rather than running water to do this. For alkaline water
Borax is suggested, again in a small amount. The slightly
alkaline wash is suggested for clearing stained highlights.
I am now trying to remember what treatment is suggested
for regenerating faded prints. Its either long storage in
the dark or possibly wetting the print.
