Baking soda is a versatile household item that can effectively remove rust from cars. It works by reacting with rust, a form of iron oxide, and breaking it down into a more manageable form. This makes cleaning easier and helps restore the metal’s appearance.
How Does Baking Soda Remove Rust from Cars?
Baking soda, or sodium bicarbonate, is mildly abrasive and slightly alkaline. When mixed with water, it forms a paste that can scrub away rust without damaging the underlying metal. The alkaline nature of baking soda helps neutralize acids that contribute to rust formation, making it an effective rust remover.

- Prepare the Surface: Clean the rusted area with soap and water to remove dirt and debris.
- Make a Paste: Mix baking soda with water to form a thick paste.
- Apply the Paste: Spread the paste over the rusted area, ensuring full coverage.
- Let it Sit: Allow the paste to sit for 15-20 minutes to break down the rust.
- Scrub the Area: Use a brush or sponge to scrub the area gently.
- Rinse and Dry: Rinse the area with water and dry it thoroughly to prevent further rusting.
