White or distilled vinegar is reasonably pure acetic acid at about 5% and can be used as a stop bath by diluting with an equal volume of water. There is considerable information about using vinegar in place of acetic acid in the WW-2 edition of the _Photo-Lab-Index_ mostly from Kodak. Acetic acid was a strategic material and in short supply for civilian purposes so the use of vinegar was a necessity.Hello all,this was discussed a few years back, but do not remember the details. I have 3 gallons of kitchen vinegar and I remember it was mentioned that a dilution of vinegar could be used as a stop bath. Does anybody know what dilution of vinegar to water I should use? Are there any disadvantages to using diluted vinegar as opposed to the Indicator Stop made by the great yellow Father or Ilford's Stop bath? If I do use diluted vinegar, how can I tell when I should dump the bath?Cheers, Bogdan
