This answer depends on the purpose for which copper is being used. In the case of cookware, you can clean the pots and pans as soon as they tarnish or leave them to tarnish on purpose to achieve an aged look. However, when copper gets in touch with your water, like in copper vessels, or your skin, like in jewelry, you should make copper cleaning a more regular practice.
There are quite a few ways you can clean copper, from using conventional store-bought products to using home-made cleaning solutions. These substances usually contain a mild acid, which reacts with the copper surface to create soluble copper salts which can be washed off.
If the copper has a lacquered finish, all you need is some water and dish soap to remove dust and grime. You will recognize lacquered finish on copper which is glossy and shiny and does not tarnish over time. If, however, this finish has been damaged, you will notice tarnished spots.
Cleaning lacquered finish is very difficult, so your best bet would be to remove it entirely and follow the steps below. However, you should never clean your copper utensils in a dishwasher, as the harsh chemicals used in some dishwashers can shorten their lifespan. Also, you should never use cleaners which contain bleach, as it can cause the copper to corrode and pit. Instead, you can try out some of the following copper-friendly ways to clean your copper items:.
There are many different products which are specially made for cleaning copper. They usually come as creams or pastes, allowing for a thorough cleaning which does not damage the copper. However, such products can be expensive and filled with chemicals.

From ketchup to vinegar, these items have two things in common: they are acidic, and they do not scrub or scratch the surface of the copper. In fact, you should avoid scrubbing the surface, because this will damage the copper finish, giving the item a scratched and damaged look.
Here are some ways you can clean copper using natural ingredients:. The acidity of ketchup is useful for a quick clean of lightly tarnished copper. All you need to do is cover the copper item in ketchup, let it sit for a while, and then rub until the tarnish has vanished.
Finally, clean the copper with warm water and some dish soap and polish it with a clean, soft, dry cloth. Like ketchup, Worcestershire sauce has acidic properties which can take away the tarnish from copper. Apply it on the copper surface, let it sit for a while, and then gently rub the tarnish off.

The paste from the tamarind fruit is acidic, reacting with the copper to remove any tarnish and restore luster.
Rinse the copper surface and scrub it with the tamarind pulp until the luster returns. You can put this mixture in a spray bottle or apply the mixture with a soft cloth. Once applied, leave it to take effect for around 30 minutes and rinse and dry. If there is more tarnish present, repeat the process, and if there are dents holding any grime, use a soft toothbrush to gently scrub the copper. This is a mildly aggressive method, where you need to mix several teaspoons of lemon juice with 1 or 2 tablespoons of baking soda.
Use a soft cloth to apply the mixture on the copper surface and rub it gently. Finally, rinse with water and polish the copper with a soft cloth. If you are dealing with more stubborn tarnish, you can try to polish the copper with this mixture. Mix 3 tablespoons of flour, 3 tablespoons of salt, and enough vinegar to form a loose paste. Spread the mixture thickly onto the copper surface with a soft cloth, giving it a bit of buffing as you spread it. Place the item in a plastic bag or cover it with plastic wrap and let it sit for a few hours or even overnight.
