Mix equal parts of lemon juice and borax in a spray bottle for large items or in a bucket for smaller items.
Spray the rust thoroughly with the lemon juice-borax mixture, or immerse smaller items directly in the solution.
Wait 30 minutes for the solution to work on the rust.
Scrub the rust spots with a rag to loosen bits of rust from the metal.
Rinse small items by holding them under running water. Rinse large items with a rag and a bucket of warm water. Rinse the rag frequently, and change the water as necessary.
Dry the item with a soft cloth.
If rust remains, repeat the entire process. The second time, focus on spraying the solution into nooks and detailed areas. Thick rust sometimes requires a third treatment.
