Removing Varnish Coating From Copper Pans: Effective Methods

If you've purchased a copper pan, you may notice it has a coating or lacquer, which keeps the copper from tarnishing. If you plan to use the pan for decoration only, you can leave the coating intact and simply dust it off from time to time using a soft cloth. However, if you intend to cook with your copper pan, you must remove the coating first. If you cook with the lacquer coating, it will burn and blacken your copper pot, which you will find difficult to remove.

There are several methods you can use to remove the varnish coating from your copper pan. One method is to mix 1 tablespoon of baking soda for each quart of water in a large stockpot or pot large enough to contain your copper pan. Bring the baking soda-water solution to a boil, then place your copper pan in the boiling water for 15 minutes. If your copper pan cannot fit into the pot, dip half of the pan into the pot and allow it to boil for 15 minutes, then rotate the other half of the pan into the boiling water for an additional 15 minutes. Remove the pan from the boiling water and wash it with hot water. If you notice any lacquer coating still stuck on the pan, you can use acetone nail polish remover to remove the remaining coating.

Another method is to use a commercial lacquer thinner on your copper pan with a soft cloth to remove particularly stubborn coatings. Lacquer thinner can be found in paint and hardware stores. You can also try using oven cleaner, acetone mixed with ammonia, or nail polish remover to remove the varnish coating from your copper pan.

How to Remove Varnish Coating Off Copper Pan

Use a solution of baking soda and water

To remove varnish from a copper pan using a solution of baking soda and water, begin by filling a large stockpot or canning kettle with water and placing it on the stove. For each quart of water, add one tablespoon of baking soda. Bring this solution to a boil.

Next, carefully place your copper pan into the large pot of boiling water. Ensure the pan is fully immersed, or, if it's too large, use tongs to dip half of the pan into the boiling water and baking soda solution. Allow the pan to boil in the solution for around 15 minutes. If the coating hasn't peeled off, rotate the pan and let the other half boil for another 15 minutes.

Once the pan has spent sufficient time in the boiling solution, remove it and scrub it with a soft cloth or sponge, using a copper cleaner or polish of your choice. You may need to repeat this process several times to remove stubborn spots.

If this method doesn't work, you can try using a commercial lacquer thinner, available at hardware stores. Be sure to test these products on an inconspicuous area of your pan first, to ensure they don't cause corrosion.

Boil the pan in water

Boiling your copper pan in water is an effective way to remove the varnish coating. This method is best if you don't have access to commercial products like oven cleaner, acetone, or lacquer thinner.

To begin, fill a large stockpot or canning kettle with enough water to completely immerse your copper pan. If your copper pan is too large to fit inside another pot, you can use tongs to dip half of the pan into the boiling water at a time. For every quart of water, add one tablespoon of baking soda. Bring this solution to a boil.

Once the solution is boiling, place your copper pan inside the pot and allow it to boil for 15 to 30 minutes. You should begin to see the varnish coating soften and peel off. If your pan is too large to be submerged completely, you can use tongs to rotate the pan so that the other half is immersed in the boiling solution.

After boiling, remove the pan from the solution. You can then wash the pan in warm, soapy water, scrubbing with a nylon scrubber or soft cloth to remove any remaining softened coating. Avoid using steel wool or abrasive products, as these can scratch the copper. If there is any stubborn coating still stuck to the pan, you can use acetone nail polish remover to remove it. Saturate a cotton ball with the nail polish remover and wipe away the remaining coating.

Finally, clean your copper pan with a copper cleaner and a soft sponge. This process will effectively remove the varnish coating from your copper pan and prepare it for cooking.

Use acetone nail polish remover

To remove varnish from a copper pan using acetone nail polish remover, you can follow these steps:

Firstly, it is important to note that acetone is flammable, so this process should be done outside or in a well-ventilated area. Ensure you are wearing protective gear, such as safety goggles and rubber gloves, to shield yourself from any potential harm.

Next, saturate a cloth or cotton balls with the acetone nail polish remover. Then, rub the cloth/cotton balls on the coated areas of the copper pan. You may need to apply a bit of "elbow grease" and scrub vigorously to remove the varnish. This process may take some time, so be prepared for that.

After removing the varnish, wash the pan with warm, soapy water and a soft cloth or sponge. Avoid using abrasive products like steel wool, as these can scratch the copper.

If there is any remaining lacquer coating stuck on the pan, you can repeat the process by saturating more cotton balls with the acetone nail polish remover and gently wiping the affected areas.

Finally, dry the pan thoroughly with a clean, soft cloth or towel.

This method is a straightforward way to remove varnish from a copper pan using acetone nail polish remover.

Try a commercial lacquer thinner

If the above methods do not work for you, you may have to resort to using a commercial lacquer thinner. This is a more potent option than nail polish remover.

Firstly, make sure you are wearing gloves to protect your hands. Then, read and follow the instructions on the commercial lacquer thinner box. You will likely need to rinse the item thoroughly with hot water and soap, and then wipe off any excess water with a soft cloth.

Buff the item with a dry cloth, using circular motions, and then clean and polish the copper piece as required.

It is important to note that once you have removed the lacquer, your copper article will start to tarnish. Over time, it will start to turn different shades of brown, from light to dark. However, with proper care, you can maintain the original colour of the copper.

Use oven cleaner

Using Oven Cleaner to Remove Varnish from a Copper Pan

If you've purchased a copper pan, you may notice that it has a coating or lacquer to prevent tarnishing. If you plan to use the pan for cooking, it's important to remove this coating first, as the lacquer will burn and blacken the pan when heated, which will be difficult to remove.

Oven cleaner is an effective method to remove the varnish coating from a copper pan. Here is a step-by-step guide:

Step 1: Prepare the Workspace

Before you begin, ensure you have adequate ventilation by working in a well-ventilated area or outdoors. Oven cleaners can release strong fumes, so it's important to work in a safe environment. Put on protective gear, including gloves and safety goggles, to shield your skin and eyes from the chemicals.

Step 2: Apply the Oven Cleaner

Place your copper pan on a flat surface or in a sink, ensuring it is stable and secure. Generously spray the oven cleaner onto the coated areas of the pan. Make sure to follow the instructions on the oven cleaner product you are using, as application methods may vary.

Step 3: Allow the Cleaner to Work

Let the oven cleaner sit on the pan for the amount of time specified in the product instructions. This typically ranges from a few minutes to around 30 minutes, depending on the strength of the cleaner and the type of coating. You should see the coating start to dissolve or soften during this time.

Step 4: Wipe Away the Coating

Using a soft sponge or cloth, gently wipe away the dissolved coating. Rinse the pan with warm water to remove any remaining residue. You may need to repeat the process if there is still some coating left on the pan.

Step 5: Neutralise the Cleaner and Rinse

After removing the coating, neutralise any remaining oven cleaner residue by applying a small amount of mild dish soap to the pan and rinsing it thoroughly with warm water. Ensure that you thoroughly dry the pan with a soft cloth after rinsing.

Step 6: Final Cleaning (Optional)

If desired, you can finish by polishing the pan with a commercial copper cleaner and a soft sponge to restore its shine.

By following these steps, you can effectively remove the varnish coating from your copper pan using oven cleaner. Remember to always work in a well-ventilated area and wear protective gear when handling oven cleaners and other chemicals.
