How do I remove rust from a concrete driveway?

To remove rust from a concrete driveway, start by mixing equal parts of white vinegar and water in a spray bottle. Spray the solution directly onto the rust stains and let it sit for about 10-15 minutes. Then, scrub the area with a stiff-bristle brush and rinse with water. For stubborn stains, you can use a commercial rust remover or a paste made of baking soda and water for additional scrubbing.
