Tarnish - General Information

Tarnish is created by warm air, dust, and sunlight. Heated air contains a small amount of carbon and sulfide (a mixture similar to smog), which chemically react with the surface of silver and cause tarnish to develop. In air, a silver object can tarnish owing to the reaction of silver with hydrogen sulfide naturally present in the air.

Silver and silver-plated objects naturally react with sulfur and sulfur compounds to produce silver sulfide (Ag2S), or tarnish. Contact of silver and silver-plated items with materials which contain sulfur compounds, such as hardboiled eggs, mayonnaise, mustard, and rubber bands will also cause tarnish.

The chemical reaction of silver with hydrogen sulfide to form tarnish is shown below:


Care tips

    • Silver left unused and uncared for will tarnish. However silver that is daily used will shine. Therefore, the more frequent you use your silverware, the less chance it will tarnish at all.


    • Acids and salts contained in food cause silver to oxidize. The prolonged contact of acidic substances with silver can damage the silver product. Get into the habit of washing your silverware after use with soft sponge and hot soapy water. Rinse it afterwards in clean, hot water and dry it with a soft flannel towel.


    • When your silver needs brightening, use a silver cleaning polish and follow its instruction. Today’s tarnish silver polishes make silver cleaning easy and infrequent task.


  • Silver is a very soft metal. It is normal that it gets scratched with use. When cleaning your silver, rub each piece lengthwise, NEVER crosswise or in circular motion to avoid heavily scratching the silver surface.

How often do you need to clean the silverware

    • Cleaning the silverware depends mostly on the conditions of their storage. The less heat and humidity of the storage, the less is the frequency of cleaning.


    • It is highly advisable that the silver is cleaned as soon as the silver starts tarnishing (starts to become yellowish).


    • If tarnish cleaning is NOT performed occasionally, heavy tarnishing will build up which might lead the tarnish color to change from yellow to black. Cleaning will then become difficult and it will cause heavy scratching of the silver, and even might need to be polished on specialized machine to be able to remove the heavy tarnish.


  • If silver is not being used, it is advisable that it is stored in specially impregnated anti tarnish pouch.


  • It is imperative to occasional visually inspect the silverware stock for its appearance and tarnish situation.

Handling and storage

    • Display or store silver away from heat or sunlight. The ideal temperature to display or store silver is 18°C (65°F). Store all silverware at a room temperature between 15˚C & 25˚C. The higher the temperature, the more humidity, and the more the silverware will tarnish.


    • For large storage room, It is highly recommended to use a dehumidifier to reduce the humidity in the storage area to about 40%. The less humid the better the silver is protected.


    • All silverware must be handled with utmost care. Do not put silverware items into each other as they will be scratch beyond repair. Even heavy polishing will not remove the scratches if this occurs.


    • USE HAND WASHING and CLEANING whenever possible.


    • ONLY Professional silver cleaning compound must be used.


Do not under any circumstances

    • Clean your silver Except with Soapy Soft Sponge. No scouring pads, Jiffy compounds, or bleaching compounds are allowed. The use of these items will IRREVOCABLY damage the silver.


    • Use unknown Polishing and Anti Tarnish Compound. ONLY Professional silver cleaning compound must be used.


    • Leave food, sauce, acids and salts overnight in your silver.


    • Store your silverware in Humid places


    • Wash silver on a rubber mat. Rubber contains sulfur that darkens the surface of silver and leaves black marks only a silversmith can remove.



SIOM’s silverware are dishwasher safe.

Please follow the guidelines below before using the dishwasher.


    • Clean your silver with Soapy Soft Sponge to remove all food residues before placing it into the dishwasher.


    • Follow the dishwasher instructions concerning the soft water required. Water with high hardness and mineral content can be corrosive.


    • Segregate your flatware and place them according to their type together (i.e. Knives / Forks / Spoons). Place the segregated items in similar directions. (ex: blades down for knives, prongs down for forks). This helps to avoid items scratching each other.


    • The alkaline content in some detergents (high phosphate dishwasher soap) is harmful to Silver, a mild detergent without bleach is recommended.


    • NEVER wash silver and stainless steel together. Always wash silver plated articles separately. An electrolytic reaction occurs when silver and stainless steel are washed together. Ions of silver disassociate, transfer to stainless steel, and leave silver articles pitted.
