Easy way to remove rust from metal12/5/2023 ![]() The carbonic acid that is formed in this reaction is weaker than the acetic acid and it helps to dissolve the rust. The acetic acid in the vinegar reacts with the baking soda (sodium bicarbonate) to form carbonic acid (H2CO3), water (H2O) and sodium acetate (C2H3NaO2). The chemical reaction that occurs between vinegar and baking soda is an acid-base reaction. Additionally, the abrasive properties of the baking soda can help to scrub away the rust particles. When mixed together, the acetic acid in the vinegar and the baking soda react to form carbonic acid, which can help to dissolve the rust. ![]() Baking soda also acts as a pH buffer, neutralizing the acidity of the vinegar. The acidity in the vinegar reacts with the rust, breaking down the rust into a form that can be easily removed.īaking soda ( sodium bicarbonate) is a mild abrasive that can help scrub away rust. White vinegar, also known as acetic acid, is a mild acid that can dissolve and loosen rust. Note that some of these methods may not work for heavy rust and severe corrosion, and in those cases the use of chemical compounds such as strong acid may be required. Sandblasting is a powerful way to remove rust from metal surfaces but it takes proper set up and room outside to do this.
