Don't soak the pennies for too long. After a few minutes, the same reaction that dissolves stuck-on grime can begin to eat away at the copper.
Yes, vinegar can react with certain metals and cause them to turn black. This is often due to the formation of metal oxides or other compounds on the metal's surface.
Acid based cleaners will eat away at a coin's surface diminishing its value. According to research professor Vinod Patel, washing common coins with natural white vinegar and iodized salt in distilled water is a non destructive way of cleaning them.
The only risk of going to long is you lose the flavor you wanted. I had some wine vinegar sitting in a basement for over a year exposed to air and that actually went bad, as in it tasted really bad and seemed to lose some acidity it previously had. But that was a really long time.
To tackle items with significant corrosion, submerge your rusty tools or knives in a bowl of white vinegar and let them sit overnight or as long as 24 hours. Once they have had a good soak, remove them from the vinegar and scrub the rust off with steel wool, a scouring pad, or a wire brush.
Consuming more than 1-2 tablespoons in a day can cause irritation of the esophagus, erode tooth enamel and most dangerously, decrease potassium levels. Those taking diuretics and/or insulin should consult their doctor before changing any dietary practices.
Pour a few ounces of vinegar into a shallow, non-metal dish. Add a pinch of salt and allow it to dissolve. Soak coins in the solution for 20-30 seconds. Remove pennies one by one, gently rubbing them with your fingers to polish them.
The 1982 penny is valuable because it was a transitional year when the U.S. Mint switched from copper to zinc, leading to a mix of compositions and errors.
When copper oxidizes, it turns a blue-green color, forming a compound called malachite. In Bowl 2, the vinegar and salt create a chemical reaction. This reaction dissolves the copper oxide (the dirty looking spots) and some of the copper on the outside of the penny. The result is a shiny looking penny!
Some of the most valuable pennies include the 1943 copper Lincoln cent, 1955 double die Lincoln cent, 1909-S VDB Lincoln cent, and the 1873 Indian Head penny with a doubled "LIBERTY". How can I tell if my penny is valuable? Check for key dates, mint marks, and errors. Research its history for rarity and demand.
Slowly add vinegar or lemon juice to the mixture and stir until a thick, smooth paste forms. Apply paste to the heavily tarnished areas of the copper item. Let the paste sit for approximately 30 minutes to one hour.
Vinegar can dull brass if left on the surface for too long or if the brass is scrubbed too hard with vinegar. Use vinegar sparingly when cleaning brass, and always use it mixed with water or other products to minimize the abrasiveness.
Why does metal change colour after being drenched in vinegar? It is because vinegar is an acid and it reacts with metal like all other acids do.

Can you clean coins with hydrogen peroxide? Yes, you can use hydrogen peroxide to clean coins. It can remove stains and tarnish and won't damage your coins' surface.
The 1944 Wheat Penny is one of the coins with the highest mintages ever- over 2 billion. Therefore, they are not quite valuable, and they are practically worthless in lower grades. Generally, the price range for these coins in fine and extra condition ranges from $0.20 to $0.50, regardless of the mint mark.
How it Works: The vinegar, which is an acid, will dissolve the copper oxide layer of the pennies. This will allow the copper to easily mix with oxygen in the air. The copper and oxygen, along with chlorine from the salt, will combine to create the blueish-green compound malachite.
Some species produce pigments on solid growth medium and can produce different types of polysaccharides. These bacteria are found in substrates containing sugar and/or ethanol, such as fruit juices, wine, cider, beer, and vinegar.
White vinegar, also known as distilled vinegar or spirit vinegar, is made by fermenting grain alcohol (ethanol) which then turns into acetic acid. Water is then added to the vinegar, so white vinegar is made of five to ten percent acetic acid and ninety to ninety-five percent water.
