Copper Care: Removing Scratches From Copper Pans

Copper cookware is a sight to behold and a pleasure to cook with. However, copper does require more maintenance than other metals. One common issue with copper pans is scratching, which can occur when using metal utensils or harsh sponges. While some people prefer the patina that develops on copper over time, others may want to remove scratches to restore the original shine. To remove scratches from copper pans, one can use sandpaper, starting with a higher grit size for deeper scratches and gradually decreasing the grit size until the surface is smooth. Another option is to use a mild abrasive like lemon and salt or a combination of vinegar, salt, and flour to create a slurry for polishing. Commercial copper polishes are also available for removing severe tarnish. Additionally, it is important to avoid using harsh sponges and metal utensils to prevent further scratching.

Using sandpaper to remove scratches

Sandpaper can be used to remove scratches from copper pans, but it requires patience and the proper grit sizes. Here is a step-by-step guide:

• Assess the Scratches: Before starting, evaluate the depth of the scratches on your copper pan. Deep scratches will require a coarser grit size, while finer scratches can be addressed with a higher grit number.
• Choose the Right Grit Size: For deep scratches, start with a lower grit size such as 320 or 400. For finer scratches, you can start with a higher grit size like 600.
• Sand in One Direction: Always sand in one direction, following the natural grain or pattern of the copper. Avoid sanding back and forth or against the grain, as this can cause further damage.
• Start Sanding: Apply the sandpaper to the scratched area, using gentle and consistent pressure. Work the sandpaper in the same direction as the grain, removing the scratches.
• Progress to Finer Grits: Once the scratches are no longer visible, move on to a finer grit size. For example, you can progress from 400 to 600, and then to even finer grits like 1500 or 2000.
• Alternate Directions: With each change to a finer grit, alternate the direction of your strokes, crossing over the previous sanding marks. This will help create a uniform finish.
• Sand Until Marks Disappear: Continue sanding with each finer grit until there are no visible marks from the previous grit. This process may take some time and effort, but it is important for achieving a smooth and consistent finish.
• Prepare for Polishing: Once you have removed the scratches and the surface is uniform, your copper pan will be ready for polishing. You can use a specialty copper polish or try a natural method, such as lemon juice and baking soda.

Remember, using sandpaper on copper requires care and attention to detail. Always assess the scratches first and choose the appropriate grit size. Work carefully and methodically, following the grain of the copper, and take your time progressing through the grit sizes for the best results.

Lemon and salt to scrub the pan

Lemon and salt are a natural and effective method for cleaning copper pans. The citric acid in lemon juice reacts with the tarnish, breaking its bond with the copper surface, while the salt acts as a mild abrasive to scrub away the tarnish without damaging the metal.

To clean your copper pans with lemon and salt, start by washing the pan in warm soapy water with a soft sponge to remove any dust or grease. Next, cut a fresh lemon in half and dip it in table salt. Then, gently scrub the copper surface with the lemon. For more stubborn stains, squeeze the lemon juice into a bowl, mix with the salt to form a paste, and apply this to the pan with a spoon. Leave the paste on the pan for up to half an hour, scrubbing periodically. Finally, rinse the pan with warm water and dry thoroughly.

This method is not recommended for lacquered copper. To identify lacquered copper, look for a shiny, glossy finish that does not change colour or brown with use.

Using a mild dish soap

To get scratches out of copper pans, one method is to use a mild dish soap. This is an effective way to remove tarnish from copper pans and restore their shine. It is important to note that copper is a delicate metal that is highly reactive, so using a soft sponge, soft brush, or washcloth is recommended to avoid scratching the surface.

First, fill your copper pan with hot water and add a mild liquid dish soap, such as Dawn's Original Dishwashing Liquid or Seventh Generation's Dish Soap. Let the pan soak for about 10 to 15 minutes to allow the soap to loosen any stuck-on food or tarnish. Then, use your soft sponge or washcloth to gently scrub the interior of the pan. Focus on any areas with stuck-on food or scratches, and scrub gently until the food or tarnish is removed. Rinse the pan with warm water to remove any soap residue.

Next, dry the pan thoroughly, especially the copper exterior. This is an important step because moisture speeds up the rate at which copper tarnishes. Use a clean cotton cloth to dry the pan, and avoid air-drying to prevent water spots.

If your copper pan is lacquered, you can simply wipe down the exterior with a soft cloth and mild dish soap. Rinse off the soap thoroughly and dry the pan well before putting it away or displaying it.

In addition to using mild dish soap, there are other methods you can try to remove scratches from your copper pans. One popular method is to create a paste or slurry using an acid (such as lemon juice or vinegar) and salt. Apply this paste to the scratches and let it sit for a few minutes before rinsing and drying your pan. You can also try using commercial copper cleaners, such as Bar Keepers Friend or Wright's Copper Cream, which are designed to remove tarnish and restore shine. However, always spot-test these products first and follow the directions carefully to avoid damaging your copper pans.

Using a cellulose sponge

Cellulose sponges are made from plant-based fibres, usually wood pulp, and are an effective, gentle tool for cleaning and polishing copper pans. They are soft, non-abrasive, and won't scratch copper. They are also highly absorbent, making them ideal for washing and polishing.

To clean and polish copper pans with a cellulose sponge, start by filling your pan with warm water and adding a mild dish soap. Avoid using harsh or abrasive sponges, as these can damage the pan's surface. Instead, opt for a non-abrasive cellulose sponge, which is gentle yet effective in removing stuck-on food and stains. Wash the pan with the sponge, applying gentle pressure to avoid scratching the surface. Once the pan is clean, dry it thoroughly with a clean cotton cloth to prevent water spots.

For a more intensive polish, you can create a paste by combining two parts ketchup with one part fine sea salt. Apply the paste evenly to the pan using the cellulose sponge and let it sit for several minutes. Then, wash the pan with cold water and dry it completely with a clean cotton cloth. Avoid using paper towels, as certain kinds can scratch the copper.

If you prefer a more natural solution, you can make a slurry by combining one tablespoon of fine sea salt with half a cup of distilled white vinegar. Add just enough all-purpose flour to create a thin paste, similar to the consistency of glue. Dip the cellulose sponge into the slurry and wipe it over the copper surface for about 30 seconds. Wash the pan with warm, soapy water and dry it thoroughly with a clean cloth to maintain its shine and prevent tarnishing.

While cellulose sponges are effective for removing light scratches and maintaining the shine of copper pans, they may not be suitable for removing deep scratches. For more severe scratches, you may need to use a commercial copper polish or a fine-grit sandpaper for a more intensive polish.

Using commercial polishes

If your copper pan is badly tarnished, commercial polishes are the way to go. They are typically more abrasive and will get the job done faster and with less effort.

For removing severe tarnish, the experts recommend a few different products. These include Matfer Bourgeat Bistro Copper Cleaning Paste, Mauviel Copperbrill, Bar Keepers Friend Soft Cleanser, Wright’s Copper Cream, Flitz Paste Polish, Red Bear Copper and Brass Polish, and Coppersmith's Polish.

Bar Keepers Friend Soft Cleanser is more abrasive, so it is perfect for removing a lot of buildup. However, it should be used sparingly as it can introduce tiny scratches to the surface of the copper. Wright's Copper Cream, on the other hand, has the fewest caustic compounds and no abrasives, so it polishes well without scratching. Flitz Paste Polish is another good option that has been recommended by multiple people.

If you are looking for a high bright shine, Bistro copper polish is a great option. It was developed by the well-known Danish silversmiths, the Jensens, and is known for giving copper a high, bright sheen. It also has a tarnish retardant chemical that will postpone the next cleaning session.

When using commercial polishes, it is important to remember to avoid getting these polishes on tin linings as they can cause damage. Additionally, always wear protective gloves when handling these products and make sure to remove any excess polish from the nooks and crannies of your pan to avoid verdigris build-up.
