<bot>: To clean rusty canning jars without a special cleaner, you can try submerging them in a solution of water and white vinegar for 15 minutes. After that, scrub the jars with baking soda and a sponge or brush to remove the rust. You can then rinse it with water and use a kitchen cloth to dry it.
