I need a way to clean silver jewelry to remove the black oxidation.

Plain white toothpaste without whitening or anything in it and a tooth brush.

You have a lot of acid in your system, happens to a lot of people. Toothpaste, not gel, works well.

Use a silver polishing cloth.

A piece of wool cloth will work too

Hello. I use a polishing cloth made for jewelry. It will take all of the tarnish right off.

I am so glad it worked for you. I found that works much better than silver polish as you can get it off with no residual left in cracks and crevices. It definitely looks much better!

I make my own cleaner. I mix one tablespoon of each: salt, baking soda and dish detergent. You will also need a cup of water and a small piece of aluminum foil. Heat the water in the microwave for 1 - 2 minutes. Place the foil in the bottom of a cereal bowl. Put the salt, b soda and dish soap in the bowl on top of foil. Then pour the hot water in and mix. Put the jewelry in and let it set for 5 or 10 mins. Then rinse in cool water and dry with a soft cloth. Discard the solution and the job is done.

I put foil in a shallow dish put jewelry in and cover with plane white vinegar for about five minutes, rince ,dry, done.

Glad the toothpaste worked. I had no doubt it would.

I sell a lot of silver on Ebay. Jewelry, silverware, serving sets. Silver polish and dips tend to remove some of the metal. The foil method doesn't work that great and still leaves a grey film that still needs to be removed AND it also removes some of the metal. I use white toothpaste (not gel)and a damp toothbrush. For large items I use a damp cloth. Also works on copper, brass, gold, porcelain, ceramics, sneakers, plastics, etc. For my sales I needed one product for cleaning everything.

Very good advice. Is it difficult to find “plain” toothpaste tho?

When your shine returns, put a piece of chalk in your jewelry box, it will retain its beauty. I agree with cleaning with toothpaste, my birthstone is opal, a delicate stone, and a soft bristle toothbrush are my best tested.

James Avery sells a cleaning cloth that cleaned my jewelry so nice taking all the black stains.

and guess what? It was only $3.50

Are you sure they are sterling? I would take it to a good named jeweler and see if perhaps it is not pure sterling. I have never heard of sterling turning pink. Could it be silver plate and it is wearing off? Perhaps the pink tint is the underlying metal coming through.

silver si cleaned with "bicarbonato " and water . A glass of water and two spoons of bicarbonato . put jewerly it half an hour . After celan with a towel

I agree the jewelry cloth is the best. I have also used Tarn X. You can also buy ultra sonic cleaner which works well too.

Buy a cloth made for silver. Works for me.

I had a jeweler tell me to use fluoride toothpaste and a tooth brush. Thats all I have used for 30 years it works great. I have the same problem even with sterling silver.

These are many ways to clean your silver, try one of these:

No more tarnishing with aluminum

Boil 4 cups of water, a tablespoon of baking soda, and some aluminum foil. Place silverware in for 10 seconds then remove with kitchen tongs.

Ketchup isn’t just for eating

Tarnished silver can be polished with ketchup using a paper towel – for silver that has crevices, use a toothbrush.

Kill two birds with one stone

When using Windex to clean your windows, spray some on a rag and use it to scrub your silver.

Brush your silver with toothpaste

Use circular motions to brush non-gel and non-abrasive toothpaste onto silver. Leave on for five minutes before washing off with water.

Use soda for tarnished silver

Fill a plastic bowl with lemon-lime soda and place slightly tarnished silver in it for one hour. Rinse and dry with a paper towel.
