My father's tefillin (z''l) turned up in a storage box. Unfortunately the box, which had been left open in the basement, was misused as a catbox (by the cat, not by human intention). The tefillin are now quite odiferous; quite likely they are as ruined as if they had been in a flood, and should be properly sent to genizah, but I would like to be sure I'm not missing anything.
From a practical point of view is there any legal and reasonable step to take to remove this odor? I've seen baking soda and saddle soap each mentioned elsewhere but I don't want to mistreat these holy objects.
If there is no legal and practical way to make the tefillin usable again, is there an organization I should contact? (Eastern United States, Philadelphia PA area)
