I sell a lot of stuff on Ebay. I use white toothpaste (not gel) and a damp toothbrush. For large items I use a damp cloth. Also works on copper, brass, gold, silver, porcelain, ceramics, plastics, etc. For my sales I needed one product for cleaning everything. A dab of toothpaste on a damp toothbrush and gently brush letting it foam up. Wipe off with a damp cloth. For larger items I use a damp cloth. Toothpaste has fine marble powder in it as an abrasive.

Try using soapy water and a microfiber cloth - like the kind that clean glasses. Rub that real good on the jewelry and that will help clean them up!

Lemon juice. Mix one part water and one part lemon juice to create a soak for your jewelry. Place item in the bowl for 10-15 minutes. The magic element in this household hack is the acid from the lemon juice, however, if you find it hasn’t eaten all of the dirt and grime away, give your jewelry a quick rinse and place it back in the mixture for a few additional minutes. Once the shine has returned, rinse again with cool water (don’t douse it, use just enough) and buff dry with a clean cloth.

Baking soda, salt and aluminum foil. Line a plate or found pan with a sheet of aluminum foil, shiny side up. Lay all of your darkened costume jewelry on the foil. Mix one tablespoon salt and one tablespoon of baking soda and mix with one cup warm water. Pour into the dish. The mixture will create a chemical reaction with the foil and bubble as it cleans the jewelry. Rinse with cool water and buff dry with a clean cloth.

Toothpaste and an old toothbrush or Q-tip. Squeeze a small amount of toothpaste on to your tarnished piece of jewelry and smudge it with your finger. Once the jewelry has a thin coating, brush clean — working into the crevices — with the toothbrush. This is a great option because the slightly gritty texture of the toothpaste works hard to remove even the toughest dirt. Rinse with cool water and buff dry with a clean cloth.

Use a mild toothpaste or a bit of Borax diluted in water to soak. Then rub on a microfiber cloth.

I would use Oxi clean

Hi Mary, make a paste by mixing two parts baking soda or cornstarch with one part water to make and gently rub the paste on. Wait for it to dry and then rinse and dry.

Non-gel toothpaste and an old toothbrush or cloth should do the trick.

Make sure whatever you try, you do a small test in a hidden spot first in case there’s a bad reaction. That way you don’t ruin your piece.

You can make use of soapy water together with microfiber cloth. Or also a non-gel toothpaste and an old tooth brush.
