    I mixed up some microphen the other week and didn't have any other bottles around except for a bottle I used for developer previously but it has some silver stains(i'm guessing, it's black/dark stains at random on the inside of the bottle I couldn't clean out previously). Will that affect the developer at all? Or is the silver oxide or whatever fairly nonreactive if it's really stuck on the plastic ? :D

    A problem which does not come up when using
    one-shot chemistry. Give bleach and days of it
    a try. Shack bottle now and then and admit
    air. May work. Dan

    This *IS* one shot developer but it's mixed from a powder and I wasn't using a whole litre in a day so I put away this 600ml left over so I could do another medium format roll later.
