Lemon & Baking Soda Method: Mix equal parts lemon juice and baking soda to form a paste. Apply to the brass surface and let sit for 5-10 minutes. Scrub gently with a soft cloth and rinse thoroughly with water. Dry immediately with a clean cloth.

Store brass items in a dry place away from moisture. Use silica gel packets in storage containers to absorb humidity. Avoid exposing brass to salt water or harsh chemicals. A light coat of clear lacquer can help prevent tarnishing, though it may dull the natural shine slightly.

For heavily tarnished pieces, use a commercial brass polish following the manufacturer's instructions. Alternatively, soak the item in white vinegar for 15-30 minutes, then scrub with a soft brush. For intricate designs, use an old toothbrush to reach detailed areas.

Never use steel wool, wire brushes, or harsh abrasive cleaners as they can scratch the surface. Avoid bleach, ammonia, and acetone. Don't soak brass in water for extended periods. Keep away from extreme heat sources. Always test cleaning solutions on a small, inconspicuous area first.
