5. Lemon cleaner
Some stubborn rusty stains on porches, driveways, patios, and even garage floors are easily removable with lemon juice. Because the acid from the lemon will actually dissolve the rust very quickly. Cut the lemon in half, squeeze it directly on the stain, and let it soak for at least 15 minutes.
If the stain is still there, you can try and scrub it with a hard bristle brush. Then rinse it with clean water.
