RE: Achrived tissue viability when stored in 10% formalin
Prolonged washing in water might help. 24 hours or longer. It's probably more cost effective to do several changes of water, and use agitation. Maybe combine this with post fixation in 70% alcohol.
A couple of references that may be helpful:

Subject: Achrived tissue viability when stored in 10% formalin
The company I work for has been asked by one of our clients how long tissue
(animal) can be stored in formalin and still be viable. We have gone back to
tissue stored for ~10yrs. but the staining was poor. If there is any advice
on where we can find documentation of this information it would be
appreciated. Any thoughts on the time frame also are welcome.
