Cleaning coins with baking powder
« on: December 07, 2008, 11:57:19 AM »
This is a easy method. <-good_>

So here is how to:

take a container of some sort and fill it with water so it covers the coin/object, does not have to cover it by multiple inches though. Once inch of water is often enough.

Now put in your coin or object into the container and add baking powder. Little or much does not really matter.. Except for how thick the layer on the bottom will be. You want to be able to easily pick up the coin. (or object)

Let it sit there for a while, check it every so often. (I check every second hour or when I happen to pass by)

When it appears to be fairly clean clean off the layer of powder that is on the coin, you can do this under running water or a separate container. (if you rub the object/coin at this stage it can get scratched)

When the baking powder is off gently rub it with a paper cloth or similar.

Do this again and again until satisfied with results. <-good_>
Or combine this with other methods for better results.

This is a very gentle method and does very little damage to the coin if performed right! [-1st-]
I like to use this for Copper, silver, brass, Aluminum, copper and nickel alloy, Nickel...

On some coins I use a tumbler with saw dust and cerium oxide to get a finer shine to it when done.
(modern coins only)

Hope this helps someone. <-good_>

I use lime or lemon juice with a bit of salt,I leave it a 1/2 hr and it's usually good,also salsa or hot sause works,but takes longer and I think may damage the coin on a microscopic level
