Blackening of silverware: immerse silverware in 78℃ aluminum foil or salt water or soda water 1 ~ 3 minutes. Automatic tank washing can keep constant temperature and control time, and circulating water pump can make salt water rise and fall. This electrolytic method is effective only when the silverware is free of grease.
Polishing silverware: dry-clean with sponge or cotton fabric with polishing agent, and then polish with clean and soft towel or absorbent cotton. A good brightener leaves only an invisible protective film.
Maintenance of silverware: the preservation of silverware is as important as cleaning to protect its beauty. Silverware should not be stacked. Dry silverware should be kept in a room free of sulfur and smoke (away from heat sources) and stored in plastic containers free of sulfur and wood, with one silverware in each container. If you put it in plastic bowls and baskets after daily use, please avoid touching hard objects to prevent surface wear.
Daily cleaning of silverware: wash with warm water and common detergent, and rinse with clear water. All gold and silver products should not be rinsed with chemicals such as bleach and strong acid washing powder.
Because of the active chemical properties of silver, silver will react with sulfur dioxide in the air to produce black silver sulfide, which will make the surface of silver ornaments oxidized black. Friends who have used silverware or worn silverware have had such an experience that silverware or silverware is easy to oxidize and discolor after a period of non-use. When this happens, you don't have to worry. The following silverware maintenance methods can help your friends to relieve their troubles. Let your silverware (ornaments) restore the beautiful luster of silver.
1. You can add baking soda powder to clean water, then clean and wipe it, and then dry the water on silverware (ornaments).
2. Wipe with silver cloth and silver paste [it should be available in general jewelry stores. It is particularly important to point out that silver cloth contains special potions and cannot be washed with water].
3. Wipe the ornaments with a soft cloth dipped in some toothpaste, then wash them with clear water and wipe them with cotton cloth. (recommended)
4. Boil strong tea water (preferably green tea), dip the tea with a soft cloth and wipe the silver ornaments repeatedly. This method is suitable for jewelry with flat surface such as bracelets.
5. Soak the silverware or silverware in silver washing water, then wash it with clear water, and finally wipe it with cotton cloth and keep it dry. However, it is suggested that silver washing water should be used as little as possible, because silver washing water is a chemical product. Using the corrosiveness of silver washing water to clean silver ornaments will cause harm to silver ornaments for a long time.
6. When the silverware is not used, it is recommended to seal it with a sealed plastic bag to reduce contact with air and slow down blackening.
Finally, it is best to avoid contact with seawater and hot springs. If you don't wear it, you can put it in a container that is isolated from the air, such as flannel bags and jewelry boxes, which can make your silver ornaments look new.
