You can clean tarnished coins by putting them in Coke. It takes about 12-15 hours for the tarnish to be cleaned. This does take some of surface off and could a coin grade lower. Some of the finer features may disappear.
It takes around 1 to 2 weeks Yes, Coke will dissolve a penny, although I don't know how long it would take. The phospheric acid in Coke will connect to the copper in the penny and create copper or zinc phosphate (e.g. dissolve it). Here is an article about it: http://www.finishing.com/336/08.shtml
Soaking a penny in soda can take anywhere from a few minutes to a few hours to get it clean, depending on the level of tarnish. It's best to check the penny periodically while soaking to see if it has reached the desired level of cleanliness.
acid
Most sodas have a chemical that corrodes very reactive objects. A penny is now made from zinc which is highly reactive to soda... try this, put a tooth in coke can overnight andsee what happens
There is no real way to clean a penny. Believe me i just done this experiment and the myths about vinegar and baking soda and vinegar and salt and ketchup and hot sauce and lemon juice and salt DO NOT WORK. When i done the experiment i left them sitting over night nothing changed. The one thing that cleaned the penny the most was the lemon juice and salt and this is how that experiment goes.Step #1: Get a cup of lemon juice and add salt.Step #2: Spin the cup slowly to blend in the salt.Step #3: Add the penny and for three minutes spin the cup around.Step #4:Take the penny out and scrub it with a towel then wash it with cool water.Step #5:Enjoy a clean penny.Yes BUTTTTT ....NEVER, EVER try to clean RARE coins to make them "look better". Dumping a modern penny in Coke to see what happens is a good chemistry experiment, but don't try it with an Indian penny from your grandfather's coin collection because it'll go from being worth possibly several dollars as a collectible, down to only a cent or two as a damaged coin.

Bleach can clean a penny in a few seconds to a few minutes, depending on the concentration of the bleach and the level of oxidation on the penny's surface. It is important to monitor the cleaning process closely to avoid overexposure, which can damage the penny.
Cleaning pennies with Coke can take anywhere from a few minutes to overnight, depending on how tarnished the pennies are and how shiny you want them to be. The acid in the Coke breaks down the copper oxide on the pennies, leaving them looking shiny and new. Shake the pennies in a container with Coke, rinse them with water, and pat dry with a towel to reveal the results.
Cleaning a penny can take just a few seconds to a few minutes depending on the method used. Using a combination of vinegar and salt can quickly remove tarnish and dirt from the surface of the penny. Rubbing the penny with a cloth or soft-bristled brush can help speed up the cleaning process.
