340 gms dried sodium formate
1700 ml. w/v 90% formic acid
Distilled water to 10 liters.
Fix as usual
Rinse in running tap water after formalin fixation.
Demineralize using agitation such as electronic stir bar.
(Difficult to over deminerlize with this formula).
Usually takes 3 to 5 times longer than 5% nitric acid.
Wash well in running tap water .
Sorry don't have a reference as I am at home but have used this for several years and prefer this to all other demineralization methods except EDTA. Worked well with many IHC techniques.
