How to clean blackened silver, do-it-yourself remedies
Let's go straight to practice. Thisnatural remedyit is very useful and effective but it has a limit: it cannot be applied to clean necklaces with small links. The blackened silver, to be cleaned and polished, must come into contact with the aluminum sheet.
- Cover the entire pan with aluminum foil
- Fill the lined pan with water, you will need to put enough water to be able to completely cover the object in silver fromclean and polish
- Add a tablespoon of baking soda. Don't worry about the dosages ... basically you are cleaning a silver object, you are not preparing a high-quality pastry ... It will be enough for the baking soda to dissolve entirely in water.
- As soon as the water starts to boil, turn off the stove.
- Immerse the jewel to be cleaned in water.
- Make sure that the jewel comes into contact with the aluminum foil: move it to change and increase the contact surface. If it is a blackened ring, to clean the internal parts, you can put an extra piece of aluminum in water to insert into the hole of the same ring.
- As the silver is cleaned, you will see brownish-yellow spots appear in the water. When your silver object is clean, you can remove it from the water.
- Remove the silver object from the water and dry it with a soft, clean cloth. Also dry well in any cavities and inlets, this will allow you to remove any oxidation residues left on the object to be polished.
- When drying a necklace or a carved frame, it might be useful to take advantage of the jet of air delivered by a spray can.

Blackened silver, how to clean it
Not onlynatural remedies. To clean theblackened silveryou can take advantage of specific products that have the advantage ofclean, polish and protect silvermaking it less exposed to oxidation. The products, in fact, leave an imperceptible and invisible patina to the eye but which makes it more difficult for the silver surface to oxidize, making it shiny for longer.
To do shine silver you can undoubtedly use the natural remedy seen above but, as stated, in case of incisions or to make it shine longer, it is possible to use ad hoc products.
Among the various products on the market, we would like to point out an English polish created to clean, protect and polish silverware. It is very effective and, in the purchase package, there is a spongy applicator capable of pushing the product into any inlet, even in the case of engraved frames, designer silver plates and tight-meshed necklaces. The product in question can be bought on Amazon at a price of 10.36 euros with free shipping costs.
For all information you can visit the page:Silver Polish Foam.
The price refers to a 170 gr bottle. On Amazon there are several “polish per agento” (polishers for silver), both in paste and liquid, both forms are good and effective. Less effective are the soaked wipes which have a lower yield. Before purchasing any good product forpolish the silvermake your assessments.
Remedies for cleaning blackened silver, video
L'blackened silverit can be refurbished using the same chemical properties that opacified and then blackened the silver: the redox reactions.
For clean the blackened silveras shown in the video below, you can use common coarse salt and, if you want, add some baking soda to the hot water / salt solution. The chemical mechanism that allows clean the blackened silverit is a simple redox reaction where the protagonists (reagents) are aluminum and silver while table salt (sodium chloride), dissolved in water, function as a salt bridge.
What we see as a "black" layer is nothing but sulfur. L'blackened silver has beenoxidized by sulfurand with this trick we can solve the problem: the sulfur transfers from the silver to the aluminum layer of the silver paper which in these conditions (heat + salt bridge) is more "attractive". Knowing some chemical principles will make you more effective inpolish the silverware!
