What kind of liquid cleans pennies the best?

Answer 1

Cleaning PenniesUse copper polish if you want them shiny. Be gentle on pennies minted after 1983, though; they're copper-plated zinc, so rough polishing could remove the copper plating entirely.

You should know that you should never clean coins that may have collectible value. Even though the cleaning makes them look "shinier," such cleaning removes most or all collectible value. As strange as it may seem to those who aren't numismatists, brown or "toned" coins can be more valuable, because cleaning removes some of the original material, and can leave marks that look bad under standard 10x magnification.

I have seen coins cleaned with many household items and experimented with some myself. In one collection I purchased, the collector had even made notes of what he had cleaned various coins with and when. Although several different products will produce a bright coin, in almost every case within a few months or years the coin will look worse than it did before the cleaning.

Don't clean a penny unless your a expert at cleaning pennies. I did it when I was 10 and they still look awful. So take my advice. They will look better if you don't do it. Good luck on everything.

Answer 2

The type of liquid that cleans pennies the most is acid from pop. If you get a glass of pop and put the pennies or penny in it for three days it will come clean

Answer 3

Using a liquid with a mild acid will clean copper pennies the best. It may take time, but it does work better than nearly everything. Vinegar and lemon juice are examples of cleaners, and seem to be the best and most easily accessed mild acids. Ketchup (because of the vinegar in it) is also known as a good penny cleaner.

Answer 4

Better than what? Lemon juice is a weak acid, and the acid removes the outer layer of corrosion/oxidation revealing 'cleaner' (unoxidized) metal. But what is your other alternative for cleaning? A stronger acid would be better than lemon juice, but most people don't have stronger acids to use for cleaning pennies.

Answer 5

Lemon Juice will clean pennies better. Old pennies look dirty because, over time, the outer layer of metal( usually copper) starts to oxidize, this oxide is called a patina, it is of a greenish grey colour and is actually a form of rust. Laundry detergent is an alkaline substance and will not react with the layer of patina on the pennies, it will however clean of any fatty dirt on the pennies. The acid in the lemon juice will immediately dissolve the thin patina, leaving you with a very shiny penny.

Answer 6

The better method would be not to clean the coin at all. Except under certain very specific circumstances by professionals who know what they're doing, cleaning almost always significantly reduces the value of a coin.

Answer 7

Coca Cola is great for cleaning coins, soak and then polish.
