What is this? Combine vinegar and ketchup in bowl. Soak the jewelry in the mixture for five to ten minutes. Remove the silver pieces, dip the toothbrush into the cleaning mixture and gently scrub the silver pieces until the tarnish is gone.
Clean silver with vinegar and foil. Aluminum foil and vinegar can be used to clean tarnished silver due to a chemical process called ion exchange. A solution of vinegar and salt transfers some of the silver molecules onto the foil, removing the tarnished surface and revealing the shiny silver underneath.
Like lemon juice, vinegar is acidic, causing a chemical reaction when it comes in contact with tarnished silver.
Place silver in a freezer bag with the yolk of a hard-boiled egg to achieve a rich patina. Soak copper in a solution of water and quick fix to age the metal b>. Or soak in a mixture of water, vinegar and salt for a blue-green patina.
If you want to speed up the tarnish process but not blacken your product, spray your metal with ammonia with Windex. The ammonia turns the silver black and the small amount of ammonia in this product makes the process very slow.
Avoid hydrogen peroxide.
Although hydrogen peroxide is an excellent cleaner for toothbrushes or dentures, never use it to clean your silverware. The reaction between hydrogen peroxide and silver can cause your silverware to appear black and tarnished.
Small appliances. The plastic and glass surfaces of most small kitchen appliances, like blenders, coffee makers, and toasters, are safe to clean with vinegar, but you should avoid rubber or metal parts, which vinegar can attack. This includes stainless steel.
Do not use harsh chemicals such as bleach, acetone, etc. to clean your silver as they can dull silver and ruin the finish.
High sulfur content makes eggs an effective natural option for oxidizing sterling silver. For a chain jewelry piece, like a bracelet or necklace, use the yolks of 1 to 3 fresh eggs. For a teapot or items with larger surfaces, use about six yolks.
The patina process is very simple. You start by mixing the liver of sulfur with water, then dip, soak or simply brush the solution onto your metal. The solution reacts with the metal, resulting in either a colored or dark patina over the entire surface of the metal.
Silver turns black from hydrogen sulfide (sulphur), a substance found in air. When silver comes into contact with it, a chemical reaction takes place and a black layer forms. Silver oxidizes faster in places with a lot of light and high humidity.
Some people try to save money by using vinegar instead of acid, but vinegar will not give you accurate results. For this test, simply place a drop of acid on your silver item. If the acid turns the wrong color, then it’s a fake. If it turns the right color, the silver is real.
When silver is exposed to sulphurous gases in the air, it discolours and then darkens as it reacts with the gas and forms a surface layer of tarnish. This process is called tarnishing, as explained below in The Science of Silver Tarnishing and Its Cause.
