How to prevent rust on cast iron outdoor seating without painting?

Cast iron outdoor seating is durable and stylish, but it's prone to rust if not properly maintained. Painting isn't the only solution—here are effective ways to prevent rust without paint:

1. Regular Cleaning: Wash with mild soap and water to remove dirt and moisture that cause rust. Dry thoroughly after cleaning.

2. Apply Protective Oils: Use food-grade oils like linseed or mineral oil. Apply a thin coat and buff to create a protective barrier.

3. Use Wax: Car wax or beeswax can seal the surface. Apply, let dry, and buff for a protective shine.

4. Keep It Dry: Cover or store seating during rain or high humidity to prevent moisture buildup.

5. Rust Converters: For minor rust, apply a converter to stop spread and create a protective layer.

6. Elevate Furniture: Use feet or pads to prevent ground moisture contact.

These methods preserve cast iron's natural look while protecting it from rust. Regular maintenance is key to longevity.
