The subject of formalin neutralization is mixed up with trade secrets and bureaucratic nonsense. John Kiernan posted a useful note about ammonia ten years ago: http://www.histosearch.com/histonet/Dec03/RE.HistonetFormaldehydeB.html and there is further useful material in our archives.
Sodium bisulfite can also be used and is more convenient to handle, but I don't know what the reaction formula is or how much to use. Does anyone know?
