[Histonet] malarial pigment removal

What is the simplest and most frequently used procedure for removal of
malarial and/or formalin pigment?  I have heard concentrated sulfuric
acid works well but I do not know the time necessary in the acid.  I
have used saturated alcoholic picric acid in the past but no longer have
picric acid in my lab.  I have also heard of the Gridley technique.
I just wondered what everyone else is using.
Thanks in advance!
