    Paper Processing and White Vinegar

    hi everyone, did any one try to use white vinegar to stop developer action for ILFORD FB or RC papers instead of stop bath?
    Thank you

    Depending on the brand of stop bath they're basically the same thing. Probably different concentrations though. Vinegar = dilute acetic acid = Stop bath.
    I think Ilfostop is a different dilute acid. Citric acid as opposed to Acetic acid ?

    The White Vinegar I purchase is 5% acetic acid. One of Anchell's formulaes is 48ml of 28% acetic acid with 1 liter water. That would be 270ml of white vinegar per liter. Need to fine tune the math for proportions, but it should work.

    so 2% of acetic acid in total, and for how long to stop action in FB paper?

    As I recall, the proportion I've seen recommended in here is 1 + 1.
    The timing is the same as what you'd use for any commercial acetic acid stop bath. Between 30 seconds and one minute is what I use for 8x10 and larger.

    sounds about right. vinegar is around 5%acid and stop bath should be around 2%
