20 years! Amazing!

I'm interested in comparing the end results from using a fresh bleach to an aged bleach. For example, bleaching back a paper all the way in full strength bleach and redeveloping in sepia toner. Will the old and new bleach produce different colour in the finished print? I'm out of bromide at the moment, but I suppose I'll try it with my relatively young 1 year old batch once I get some more.
