Hello, I buy a gallon of Glacial Acetic Acid, make a 28% stock solution and then dilute from there to a working solution. It is really cheap and I only buy Glacial once or twice a year. To make 28%, dilute 3:8 or 9oz. Glacial to 24oz. water. To make a working solution dilute 48ml Acetic Acid(28%) to make 1 liter. Hope this helps, Ken
1:3 seems rather intense... Does this equal anything like a 1% - 2% solution of acetic acid?
This is a quote from Richard Knappow from Pure-Silver responding to a similar question.
Most of the distilled white vinegar I've examined locally in New England, is 5%
acetic acid. That should be diluted with two or three parts water to one part
vinegar to keep it in the range of commercial formulas. The concentration
does vary with location but is usually printed in the bottle.
Kodak SB-1 is 48 ml of 28% acetic acid per liter, or 0.28x48/1000 = 1.3%
5% acetic acid in vinegar diluted 1 + 2 is 5/3 = 1.6%,
or if diluted 1 + 3, 1.25%.
I keep in stock Kodak's acetic acid which I dilute according to the bottle's instructions. I use it while making prints in my darkroom, but since I prefer to subject my films, during processing, to as few foreign elements as possible, I use only water as a stop bath which is at the same temperature as the developer and fixer. This has never caused any film development problems at all.
I am moving to an alkaline fix regime for both films and prints so will be using a plain water stop. However I used a very similar citric acid mix to yours. I found it effective, odourless and very economical. Like you I used once and then threw it away. I will probably contiue to use stop bath for colour prints.
