How do I polish silver and brass found at garage sales?

Updated October 2026 · How we answer

Polishing Silver

For silver, start by washing with mild soap and water to remove dirt. Then apply a commercial silver polish with a soft cloth, rubbing gently in small circles. For tarnish, a paste of baking soda and water can work: mix three parts baking soda to one part water, apply with a damp cloth, rinse well, and dry. Another method is the aluminum foil and baking soda bath: line a bowl with foil, add hot water and baking soda, and soak the silver for a few minutes. Avoid using toothpaste or abrasive cleaners as they can scratch. After polishing, rinse and dry with a soft cloth to prevent water spots.

For heavily tarnished pieces, you may need to repeat. Always test on a hidden area first, especially on silver-plated items, as excessive polishing can wear away the plating.

• Wash with mild soap first.
• Use commercial silver polish or baking soda paste.
• Aluminum foil bath works for light tarnish.
• Avoid abrasive cleaners.
• Dry immediately to prevent spots.

Polishing Brass

For brass, wash with mild soap and water, then dry. Use a commercial brass polish or a homemade paste of equal parts vinegar, salt, and flour. Apply the paste with a soft cloth, let sit for a few minutes, then rinse and buff dry. For lacquered brass, do not polish; just clean with a damp cloth. For unlacquered brass, you can also use ketchup or lemon juice. Always test on a small area first. After polishing, you can apply a thin coat of wax to slow tarnishing.

Be careful not to over-polish brass, as it can remove the antique patina that some collectors value.
