Hello Michael! The spray is just generic white vinegar. At times we'll just use the stock stop bath for film and paper made from diluted glacial acetic acid. We've heard that a spritz of lemon juice looks great too. Sorry for the late reply, I have notifications set wrong and I need to fix them. We hope you're having good weather in LA and have had plenty of great Cyanotype making days. Are you using film negatives or digital negatives?
