We routinely surface decalcify the trimmed/faced block for one hour with a commercial product (Rapid Decalcifier or RDC, Cellpath) which contains Hydrochloric acid. Works a treat! Alternatively we have been known to use a splash of laundry fabric softener in the soaking water for IHC sections.
Which species of fish are you sectioning? This can make a huge difference to the timing in either solution.

Subject: [Histonet] softening agent for tissues embedded in paraffin blocks
I'm trying to cut some fish muscle samples (along with skin and some bone tissues) embedded in paraffin (fixed in Bouin's fixative and decalcified with EDTA). I find it very difficult to cut these blocks and I would like to know, based in your experience, what tissue softening agent do you recomend to solve this problem. Many thanks in advance
