Should one use the old fixer bottle to store the dilluted fixer for using, after a thorought whashing? Or is it unwise to do so?
I once had a bottle of fixer leak all over my floor... through age, I think.
What you shouldn't do is re-use bottles for different solutions (e.g. developer in a fixer bottle) - ESPECIALLY "in reverse." That is, you might get away with storing stop in a developer bottle, but I wouldn't even consider the reverse.
Besides, even though "photographic containers" are "expensive" - it's cheap enough to just buy a new one if there are ever any doubts. Personally, I prefer brown glass bottles with caps, but inevitably we all end up with those "Datatainers."
I re-use one gallon heavy plastic bottles that are originally sold containing auto windshield wiper fluid for just over US$1- at discount stores. I just use up the original contents then re-use the bottle.
I have no idea what a plastic bottle of windshield wiper fluid sells for in Portugal, but I would suggest finding out.
