Professional Oxalic Acid Rust Remover thoroughly cleans metal surface rust, renewing equipment.

Medium Strong Acid Oxalic Acid 99.6% for Plant Growth and Nutrition Improvement

Oxalic acid is an organic acid, the simplest dicarboxylic acid, with the chemical formula H2C2O4. It is a metabolite of living organisms and belongs to the category of medium strong acids. It is widely distributed in plants, animals, and fungi, and plays different functions in different living organisms. Research has found that over a hundred plant species are rich in oxalic acid, with spinach, amaranth, sugar beet, purslane, taro, sweet potato, and rhubarb having the highest content. Oxalic acid can reduce the bioavailability of mineral elements and easily form calcium oxalate with calcium ions in the human body, leading to kidney stones. Therefore, oxalic acid is often considered an antagonist of mineral element absorption and utilization. Its anhydride is carbon trioxide.

Our professional-grade oxalic acid rust remover is the ultimate solution for industrial maintenance, automotive repair, and metalworking sectors. It deeply penetrates rust layers, chemically reacting with iron oxide to convert it into soluble compounds, allowing for easy removal. It effectively softens and eliminates even heavy rust scale. This product not only restores the original appearance of metal components (such as tools, machinery, cast iron furniture, auto parts) but its "stripping" mechanism avoids the material loss and dimensional changes caused by physical grinding, making it particularly suitable for precision parts and workpieces with threads or complex geometries. After application, the metal surface is left clean and activated, which is highly conducive to the adhesion of subsequent anti-rust treatments (e.g., painting, oiling). Please note that this product activates the metal surface; if not planning immediate anti-corrosion coating after derusting, exposure to air may accelerate re-rusting. Therefore, we strongly recommend applying rust preventive oil or primer promptly after derusting, thorough rinsing, and drying. Always operate in a well-ventilated area and wear full protective gear, including acid-resistant gloves, safety goggles, and protective clothing, to avoid direct skin contact.
