This may seem silly to you...but it works HONEST!!
Buy a large can or jar of PAPRIKA (Sweet!) not the hot one...
Get a soft cloth...and a little water...
Wet the copper surface
Sprinkle a good amount of paprika on your copper...rub with the soft cloth and a little water...it should form a red paste....keep rubbing until it starts to shine. This should burnish your copper...Then rinse off well and buff dry.
(You'd better wear rubber gloves...otherwise it will take days to get it out from under your fingernails!

You can clean it by putting it in a bowl of vinegar and the next day rubbing the rest off.
OR
Vinegar and Salt. If copper is tarnished, boil article in a pot of water with 1 tablespoon salt and 1 cup white vinegar for several hours. Wash with soap in hot water. Rinse and dry.
Salt, Vinegar, and Flour. Dissolve 1 teaspoon salt in 1 cup white vinegar. Add enough flour to make a paste. Apply the paste to copper and let sit for 15 minutes to 1 hour. Rinse with clean warm water, and polish dry.
Lemon and Salt or Baking Soda. Make a paste of lemon juice and salt, and rub with a soft cloth, rinse with water, and dry. Or use a slice of lemon sprinkled with baking soda. Rub copper with the lemon slice and rinse with water and dry. Vinegar and Salt. Pour vinegar over the surface Sprinkle salt over the acid and rub in the mixture. Rinse with warm water and polish dry.
Lemon Juice and Cream of Tartar. Make a paste of lemon juice and cream of tartar. Apply, leave on for 5 minutes, and then wash in warm water. Dry with a soft cloth.
Tarnished Copper: Polish with a commercial polish for copper following directions on the container. Polish can be made at home by moistening salt with vinegar or lemon juice to make a paste for a bright finish or a paste of rotten-stone and olive oil for a dull finish. After polishing decorative items, spray with lacquer to preserve color if desired.

In the lab, I've used medium strength hydrochloric HCl acid. It attacks and dissolves the dirt and oxide layer without attacking the pure copper itself.

Apply tamarind water over the article and clean it with water next day. It will be glossy

Toothpaste works pretty good. If its an expensive item, I wouldnt clean it without talking to an appraiser/expert first

Depends on why you are cleaning it, if it is a coin, don't.
If you are soldering pipes, emery cloth and flux.
Ketchup... it is the vinigar thing, but it sticks to surfaces that you can not submerge.
