How to Clean Copper – The 11 Best Methods for Cleaning Copper
1. Wash and Dry Your Copper Pots and Pans as Usual
In most cases, hot water and a little dish soap will quickly get them clean. It is important to dry copper completely after washing, however. Water remaining on the pot encourages tarnish to form.
2. Use a Commercial Copper Cleaner
If you do find tarnish, black spots or a green-blue patina, a mildly abrasive copper cleaner such as Brasso or Wright’s Copper Cleaner quickly cleans it away. Sprinkle copper cleaner on the spot and scrub with a damp sponge. Rinse thoroughly and dry.
Perhaps you don’t have any copper cleaner, or you want to use natural cleaners. These methods are the best way to clean copper naturally:
3. Use Lemon and Salt
The acidity of the lemon, combined with the abrasiveness of the salt make quick work of mild tarnish. Cut a lemon in half and sprinkle the surface with table salt. Rub the tarnished spots with the salted lemon and rinse. Dry thoroughly.
4. Coarse Salt and Cornstarch
Two simple home remedies, coarse salt and cornstarch, make a very powerful tarnish cleaner and polish recipe:
Make a loose paste of the salt and cornstarch. Rub on copper with a soft cloth and allow to sit on tough spots and rub again. Rinse with warm water and dry with a soft cloth.
5. Use Lemon and Baking soda
Mix equal parts lemon and baking soda and rub on tarnished spots with a soft cloth. The baking soda is mildly abrasive while the acid in lemon juice dissolves the tarnish. Rinse thoroughly and dry.
6. Clean Pots with Vinegar
Soak a cloth or rag in white vinegar and apply a little elbow grease to remove tarnish from the surface of pots and pans. When the cloth becomes soiled with tarnish, move to a new section of the cloth and keep rubbing. This method takes a little work but results in a beautiful shine. Rinse the item thoroughly and dry.
You can also use this method to take care of cleaning aluminum pots and pans, as well.
7. Clean with Tomato paste
Like vinegar and lemons, tomatoes are acidic and provide the cleaning action. The thickness of the tomato paste helps hold it in position for longer cleaning time and a better shine.
You can use tomato paste, tomato sauce, or ketchup for this quick cleaning tip. Rub the tomato paste over the pot with a clean rag. Rinse and dry.
8. DIY Copper and Brass Pots Cleaner
This quick DIY brass cleaner recipe cleans copper or brass without harsh chemicals or too much work.
A quick mix and rub are all it takes:
Make a paste of the ingredients and rub on copper or brass with a soft cloth. Rinse and dry. For more on homemade copper cleaner recipes, check out our copper cleaner tips.
9. Use Lemon Juice and Cream of Tartar
Cream of tartar is a mild acid and slightly abrasive. Combine two tablespoons of cream of tartar with enough lemon juice to moisten and form a paste.
Rub the mixture on the copper with a soft cloth. Rinse and dry completely.
10. Cleaning Tough Stains and Tarnish on Copper Pans
Use a mildly abrasive sponge with any of the above methods to give extra scrubbing power for tough stains and tarnish. Use as needed and avoid scratching your copper.
It is best to avoid abrasives completely whenever possible, so use this method only if all else fails.
11. How to Clean Badly Tarnished Copper
When your copper item is badly tarnished, your first inclination might be to grab a Brillo pad or some abrasive cleanser and start scrubbing. This is a huge mistake.
Abrasives like steel wool or common cleansers can scratch the copper and leave it damaged beyond repair. The safest way to clean badly tarnished copper is to use a homemade copper cleaning paste, time, and a little elbow grease.
Mix the ingredients together to form a loose paste. Slather a thick layer of the mixture onto the copper with your hands, covering the entire item with a layer of paste.
Wrap the item and paste in plastic wrap or place it in a plastic bag and seal. Allow the copper to soak in the paste for four hours or more. Wipe away the paste from a small area with your finger.
If the copper needs more time, replace the paste, put it back in the plastic wrap, and allow it to sit overnight. Wipe off the paste and wash the copper item in hot soapy water, rinse, and dry.
Repeat the process as needed until all tarnish is removed. If only a few spots of tarnish remain, rub them with the paste and a soft cloth. Polish the copper dry with a soft cloth. Apply a thin layer of oil to prevent future tarnishing.
How to Polish Copper Bottom Pans
Copper bottom pans and pots are excellent for cooking. The copper conducts heat extremely well and heats the pan quickly and evenly.
Many people avoid them, thinking that they are hard to clean. However, cleaning copper bottom pans does not need to be a chore. Try these tips:
For everyday use, clean copper bottom pans like any other pan. Use hot soapy water and a soft cloth. Rinse thoroughly and dry the pan completely with a towel. Drying copper is necessary because water encourages the copper to tarnish.
If black spots or tarnish develop on your copper bottom pans, clean them easily following these steps:
How to Clean a Copper Sink
Your copper sink has a natural patina that protects the surface and keeps it from tarnishing. However, some foods can damage the patina or even damage the copper sink.
Follow these tips for everyday use to protect your copper sink:
How to Wax a Copper Sink
Over time, the patina on a copper kitchen or bathroom sink will begin to degrade. If this continues, the copper may tarnish. Clean and protect the copper sink by applying a high-grade plumbing wax whenever you notice that water no longer beads up on the surface.
How to Clean Copper Jewelry
When cleaning jewelry, you often have a mixture of copper and other materials including gemstones or other metals. A good DIY jewelry cleaner will clean and protect all materials.
Be sure that any method you use is safe for the other materials as well as the copper. These methods are recommended for pure copper jewelry and may not be safe for other materials. Use with care.
Cleaning Lacquered Copper Jewelry
Lacquered copper jewelry that needs cleaning, but is not tarnished, cleans easily with soapy water. Rinse it completely and dry. Then buff the dry jewelry with a jewelry polishing cloth.
Soak Copper Jewelry in a Cleaning Solution
Stir the ingredients and place the jewelry in the solution and soak for a few minutes. Remove from the solution when clean, rinse thoroughly and dry completely.
Deep Clean Copper Jewelry
When your jewelry has many crevices that need cleaning, this method is the easiest.
Place the jewelry in the solution and bring to a boil over medium-low heat. Allow the solution to boil for a few minutes.
Now remove the jewelry using tongs and allow to cool completely and rinse thoroughly and buff completely dry.
How to Clean Copper Mugs
Copper mugs clean up nicely with the use of lemon, salt, and a little elbow grease. Best of all, this method is environmentally friendly and uses only natural ingredients. There is no chemical residue to cause problems later.
If you do not have a lemon, you can accomplish the same results with vinegar and baking soda following these directions: Dip a soft cloth in vinegar and sprinkle the mug with baking soda.
Rub the mug and baking soda with the vinegar soaked cloth until the surface is shiny. Now rinse completely and dry with a towel.
How to Clean Copper Pennies
Until mid-1982, pennies were made of 95% copper. Since 1982, pennies are mostly zinc. To clean copper pennies made in 1982 or earlier, use this method:
Put the vinegar and salt in the container and add the pennies. Let them soak for 5 to 10 minutes. Remove the pennies and rub the surface with a soft cloth. Finally, rinse well and towel dry.
Is Copper Cookware Safe?
You may have read or heard that copper is poisonous and should not be used for cookware. I want to assure you that modern copper cookware is completely safe and easy to use.
Modern copper pans are lined with an alternate metal on the inside. The copper never comes into contact with your food and poses no danger.
There are a few special use copper utensils that are not lined, such as a copper bowl for beating egg whites. These utensils, when used for their intended purpose are completely safe. You have nothing to fear from modern copper cookware and utensils.
Why is Copper Best for Pots and Pans?
Copper conducts heat extremely well and spreads the heat evenly across the bottom and up the sides of the pot. Copper pots and pans have no hot spots, so you don’t have to worry about burning and sauces separating because of uneven heat.
Copper is a better conductor than aluminum or stainless steel. Many pot makers will brag about the thickness of the aluminum core designed to spread the heat.
Don’t be fooled; a good-quality copper pot is better than the thickest aluminum core, only silver conducts heat better. (And silver is a poor choice for pots and pans for many reasons.)
How to Prevent Copper from Tarnishing
Copper naturally tarnishes over time with exposure to the air and water. There are several ways to prevent tarnishing, the right method for you depends on the item and how you use it. Consider these methods to prevent tarnish on your copper items:
How to Clean Green Off Copper Pipes
The green tarnish that forms on copper pipes is no different from the tarnish that forms on your copper cookware; it is just in a more advanced stage. As copper tarnishes, it first forms brown or black spots which turn green over time.
The green tarnish is not harmful to your pipes, but it does look unsightly. If you want to clean the pipes back to their shiny copper finish, you can use any of the copper cleaning recipes we have given you above.
Probably the most used method is to rub the pipe with a salted lemon and allow it to sit for a few minutes before cleaning the lemon juice and salt off. You may need to repeat the process a few times to return the copper to its shiny surface, but it will work.
