How to remove rust spots from untreated cast iron outdoor bar stools?

Rust spots on untreated cast iron outdoor bar stools can be unsightly and damaging if left unchecked. Fortunately, removing rust is a straightforward process. Here’s how to restore your stools:

1. Scrub with Steel Wool or Wire Brush – Gently scrub the rusted areas to remove loose flakes and surface corrosion. Avoid harsh scrubbing to prevent scratches.

2. Use White Vinegar or Baking Soda Paste – Soak a cloth in white vinegar and wrap it around the rusted spots for 1-2 hours, then scrub. Alternatively, apply a baking soda-water paste, let it sit, and scrub.

3. Rinse and Dry Thoroughly – After cleaning, rinse with water and dry completely to prevent new rust formation.

4. Apply Protective Coating – To prevent future rust, coat the stools with a thin layer of mineral oil, wax, or specialized cast iron sealant.

Regular maintenance and keeping stools dry will prolong their lifespan. For stubborn rust, consider sanding and repainting with rust-resistant paint.
