I have inherited a 4oz bottle of this stuff - described on the label as "Preventing fog and stains".
I assume it is Benzotriazole. Can anyone suggest a suitable dilution for use with elderly,fogged paper? And,given it is probably 30 years old,and has a slight fine precipitate in the bottle,is it likely to be usable?
