How do I remove rust from cast iron outdoor furniture?

Cast iron outdoor furniture is durable and stylish, but over time, it can develop rust due to exposure to moisture and weather conditions. Fortunately, removing rust from cast iron is a straightforward process that can be done at home with a few simple tools and materials. Here’s a step-by-step guide to help you restore your furniture to its former glory.

1. Gather Your Supplies: You’ll need steel wool or a wire brush, white vinegar, baking soda, a sponge or cloth, and a protective sealant or paint.

2. Scrub Off Loose Rust: Use steel wool or a wire brush to scrub away loose rust from the surface. Be thorough but gentle to avoid damaging the cast iron.

3. Apply Vinegar Solution: Mix equal parts white vinegar and water in a spray bottle. Spray the solution onto the rusted areas and let it sit for 1-2 hours. The acidity of the vinegar will help dissolve the rust.

4. Scrub Again: After the vinegar has had time to work, scrub the surface again with steel wool or a brush to remove any remaining rust.

5. Neutralize with Baking Soda: Rinse the furniture with water and sprinkle baking soda over the surface to neutralize the vinegar. Scrub gently and rinse thoroughly.

6. Dry Completely: Allow the furniture to dry completely in the sun or with a clean cloth.

7. Apply a Protective Coating: To prevent future rust, apply a rust-resistant primer and paint or a clear sealant designed for outdoor use.

By following these steps, you can effectively remove rust from your cast iron outdoor furniture and extend its lifespan. Regular maintenance, such as covering or storing furniture during harsh weather, will also help keep rust at bay.
