They are all 'weak' acids, but the strongest readily available that I could think of, was the citric acid. Ascorbic is 'close enough'. The vinegar will work too using it neat. Nasty tasting vape though. lol. better to use lime juice.
we are trying to get the pH down, l< 2 is optimal, < 3 is 'sufficient' but not efficient. There are other options, but not for the kitchen.
