Dear Christine,
I am not familiar with any commercial non-aqueous deacidification process
which will not leave an alkaline buffer; indeed, if there is no buffering,
why deacidify? , Be that as it may, I do know that
deacidification/buffering is most effective if applied during he first
half-dozen years or so. Past that time, the useful effect diminishes
rapidly.
