During the recent discussion about mold growth in the
FerricAmmoniumCitrate solution (cyanotype) sombody posted a preservative,
something like formaldehyde? By mistake I deleted this post, could this
person please repost (privatly)?

Any other suggestions to inhibit bacteria, mold/fungus growth most welcome

Thanks in advance!
