The Effect of Citric Acid on Metals Hunker

Since citric acid is a weaker organic acid, it does not corrode iron rapidly. Over-the-counter solutions of citric acid are generally offered at low concentrations, so they are more safe. Dipping a piece of rusty iron into the citric acid solution starts the reaction. The citric acid chelates the iron oxide, leaving a clean piece of iron and a
