Some folk remedies for cleaning copper include scrubbing with buttermilk, using an ammonia/soapsud mixture, or (believe it or not) Toni permanent-wave solution without the neutralizer. Other folk remedies use catsup, olive oil, or baking soda with ammonia.
Mineral Cleaning By John Betts John Betts - Fine Minerals. Originally Published in Four Installments by the New York Mineralogical Club As promised this article is first in a series on how to clean mineral specimens. Many specimens collected in the field do not look like the ones that dealers are selling. Most collectors become discouraged or ...
2018-2-21 Lacquering silver and copper specimens after cleaning will keep them bright for a long time. Most copper cleaned with cyanide will have a rosy hue for a day or so after cleaning but on exposure to air will return to a nice copper color, so it is well to wait a day or two before lacquering the copper.
2020-11-19 The Statue of Liberty is a good example of what happens to copper after it has been exposed to many of these elements over a long period of time. In general,
Once clean, the mineral should be rinsed under running water, and is best soak in frequently changed water for an equal amount of time that soaked in the SIO. Conclusion I stayed clear of the more hazardous hydrofluoric, sulfuric, nitric acids and treatments for specialized uses such as
2015-6-17 Lemon juice and salt are useful for removing tarnish from copper in three easy steps: Squeeze the juice of the lemon in a bowl and then sprinkle the salt into the
2021-8-3 Protect copper with lemon juice and salt. Fill a small container with 2 parts lemon juice and 1 part salt. Stir this mixture lightly with a spoon until the salt dissolves.

As a general advice, this should be taken care of in every cleaning process. For most applications (i.e. native copper, chalcocite, bornite, fahlore, enargite), a 2% (20 g/l) solution of EDTA tetrasodium salt can be used.
The recovery of these copper minerals by flotation or hydrometallurgy from ores, typically containing 0.5%TCu (open pit mines) and 1-2%TCu (underground mines) is of great
2018-11-6 How to Clean Mineral Deposits on a Copper Pipe. Pipes for plumbing, especially copper pipe, is prone to an accumulation of mineral deposits. If you live in an area that has water that is heavily treated with chemicals you will notice more mineral deposits. This hard water carries heavy amounts of calcium and magnesium.
2020-11-19 The Statue of Liberty is a good example of what happens to copper after it has been exposed to many of these elements over a long period of time. In general, this blue-green patina actually increases the value of copper metalwork by protecting it from the elements. Though, as highly-prized as copper coins and statues might be because of their age and patina, this coloration and residue is not ...
2021-1-7 Here's how to clean copper with an old standby: vinegar. Mix 1/4 cup salt, 1/4 cup flour and enough vinegar to make a thick paste. Use a soft cloth to rub the paste on the surface of the copper. Buff the copper item until it shines. Rinse with warm water
2005-6-1 The copper only needs to remain a short time in the reagent and when you take it out you should immediately wash it off in large quantities of cold water. If you want to clean copper half breeds from Michigan I can give you another reagent to clean this
2010-7-11 Acetic Acid. Perhaps the most widely used chemical to clean copper is acetic acid. Many people may not know it, but this chemical is commonly found in homes, but called by another name: vinegar. Vinegar is actually acetic acid.

2019-12-11 Rinse the pipe thoroughly with a sponge. If you’ve used vinegar and you don’t wash it off completely, the pipe will turn green. Buff and dry the pipe with a clean cloth. Sometimes, after a polish, copper pipe can still look a bit tarnished or uneven. If so, you can use fine wire wool to scrub away remaining tarnish and to even out the surface.
The recovery of these copper minerals by flotation or hydrometallurgy from ores, typically containing 0.5%TCu (open pit mines) and 1-2%TCu (underground mines) is of great commercial importance ...
2019-11-24 availability of these little cleaning "guns" has been revolutionary for those who want to clean specimens. Its impact on cleaning minerals is like the difference between copying a book by hand using a quill and ink compared to printing it with a laser printer. These little "guns" have a short barrel.

After 10 minutes of rubbing, leave the material in the bowl for 15 minutes to rest and dissolve the mineral deposits. Brush the remains of the deposits afterward, and if necessary, pour some lemon juice to finish off the remains. Turn the water back on and repeat this process each time you get minerals
