> [!tip] Quick answer: Make a paste of salt, lemon juice, and a little flour. Apply to the copper pan with a soft cloth, rub gently in circular motions, then rinse with warm water and dry immediately. For severe tarnish, use Bar Keepers Friend or a dedicated copper cleaner. ## How to clean copper pans in 2026 Copper pans are one of the most beautiful pieces of cookware ever made and one of the highest-maintenance. They tarnish on contact with air, react with acidic foods, and lose their gleam within weeks if you don't have a routine. The good news is that the routine is simple and uses ingredients already in your kitchen. This guide covers solid copper pans (lined with tin or stainless on the cooking surface), copper-clad pans (a copper exterior over a different metal), and copper accents on stainless cookware. ### What you should plan for - Active time: 5 minutes per pan - Tools: Salt, lemon, flour, soft cloth (no abrasives) - Cost: Under $5; ingredients you already own - Frequency: After every 3 to 5 uses; weekly if displayed - Caveat: Never use steel wool, scouring pads, or acidic dishwashing detergents ## The classic lemon-salt method 1. Wash the pan with warm soapy water to remove food residue. Dry fully. 1. Sprinkle salt generously over the tarnished areas. Coarse salt is best. 1. Cut a lemon in half and use the cut side as your scrubbing tool, pressing down so the juice mixes with the salt. 1. Rub in circular motions across the tarnished areas. The tarnish lifts within 30 seconds to 2 minutes. 1. Rinse with warm water thoroughly. 1. Dry immediately with a soft microfibre. Water spots tarnish copper faster than anything else. 1. Buff with a clean dry cloth to bring out the shine. ## The flour-vinegar-salt paste (for stubborn tarnish) 1. Mix equal parts white vinegar, flour, and salt into a thick paste. 1. Apply to the pan with a soft cloth or your fingers. 1. Let sit for 15 to 30 minutes. 1. Rub gently in circular motions. 1. Rinse, dry, buff as above. The flour prevents the vinegar from running off and gives the cleaner time to work. ## What you'll need ## Inside vs outside Outside of the pan (copper exterior). Tarnish is purely cosmetic. Clean for looks, not performance. Inside of the pan (cooking surface). This is where it matters. Most copper pans have a tin or stainless lining for cooking. Never use abrasives on tin; it's soft and scratches. Stainless lining tolerates Bar Keepers Friend in a pinch. Unlined copper. Rare and dangerous for acidic foods (the copper leaches into the food). Use only for dry storage or display. ## Pan-by-pan guidance ### Mauviel and Falk (high-end French copper) Use lemon-salt only. Manufacturer recommends against commercial copper cleaners that can damage the satin finish. ### Williams Sonoma and CB2 Canada copper Same. Lemon-salt or the flour-vinegar paste. Polish lightly with Wright's once a year for display. ### Copper-clad bottoms (All-Clad Copper Core, vintage Revere Ware) The copper is thin. Clean very gently. Bar Keepers Friend with light pressure is safe. ### Copper Moscow Mule mugs Hand-wash only, never in the dishwasher. Lemon-salt restores them in minutes. ## Common mistakes 1. Putting copper in the dishwasher. Detergent etches the copper finish permanently within a few cycles. 1. Using steel wool or scouring pads. Scratches the surface. Soft microfibre only. 1. Using bleach. Discolours copper and can pit the surface. 1. Leaving water spots to dry. Water spots tarnish faster than air exposure. Always dry immediately. 1. Polishing too often. Each polish removes a tiny amount of metal. Polish for use, not weekly. ## Preventing tarnish - Dry immediately after every wash - Store in a dry cabinet, not on a wet drying rack - For display pieces, apply a thin coat of food-safe mineral oil monthly - For hung pots, wipe with a dry microfibre weekly to remove kitchen humidity ## FAQs about cleaning copper pans Why is my copper pan green?
