A paste of baking soda acts as a mild abrasive and can help lift surface rust when scrubbed.

Clean the rusty item.
Make a thick paste by mixing baking soda with a small amount of water.
Apply the paste generously over the rusted areas.
Let the paste sit for an hour or two.
Use a stiff brush, steel wool, or toothbrush to scrub the paste vigorously into the rust.
Rinse the item thoroughly with water.
Dry completely and apply protective oil.
Note: This method is better suited for lighter surface rust than the vinegar soak.

N/A - Uses a common, mildly abrasive household item for gentle rust removal.
