Do not use rough sponges for cleaning silver to avoid scratching the surface of products and not to damage small parts.

Casinogamenow apply this paste on the surface of the product. Wait until the mortar hardens. After rinse the silver with plain water and wipe dry with a rag.
Take a container of such size that it can be placed any silverware. Prepare an aqueous solution of ammonia at a ratio of 1:10 (for example, 1 tablespoon of alcohol for 10 tablespoons of water). Immerse in the resulting solution of silver ammonia for 15-30 minutes (depending on the degree of contamination of the surface of the product).
Use ammonia when cleaning silverware. Mix 5 parts water with 2 parts ammonia and 1 part of a tooth powder (if you can find it in modern shops).
