Re: Acids

it would be worth purchasing citric acid (in pure, crystalline form) and make your own solution.
Citric acid is readily available on the Internet (soapmakers use it to make "fizz-bombs"), and may be available (as "sour salt") in the canning section of your supermarket. Some winemaking stores carry it, too. I've been told pool supply stores may sell it for adjusting the pH of pools and hot tubs.

Best regards,
