I have not done any tests for longevity of cyanotype. I have only
done cyanotype for a year, so if there were any changes they are
too small for me to see without specific testing.
I don't think the buffer is such a concern. I use a weak vinegar
wash as the first bath. This may react with the buffering agent
and convert it into a salt. Perhaps someone who has done
cyanotype for a longer time can offer some better observations.
