    No, the two acids won’t work at that pH, they turn into their salt form and be nothing more than pixie dust, great for claims but nothing more.

    Thank you so much for answer.
    Are you saying that “do not use these two acids”?
    Can I use any one of them?

    At pH 8 - 9, acids become ineffective salts. So, you can’t use either if you want them to actually do anything.
