They are also very effective at dissolving minerals, which can be a major cause of clogs.<\/p>\n<p>Formic acid and citric acid are both weak acids that are not as effective at dissolving organic matter or minerals. Carbonic acid is a weak acid that is found in carbonated beverages. It is not effective at dissolving organic matter or minerals. Malic acid and lactic acid are both weak acids that are found in fruits and vegetables.
