This time, I would like to talk about the precautions to take when caring for antique cutlery (forks, knives, etc.). After using antique cutlery for a meal or other occasion, wash it with a mild detergent and a soft sponge, and then wipe off any moisture thoroughly with a cloth.
When doing so, do not use a dishwasher, dryer, or boiling water.

Silver products may become discolored when used for a long time.
The main cause of blackening is sulfide, which reacts with sulfur .
It gradually turns black by reacting with the trace amount of sulfur contained in the air, sweat, water, etc.
However, the blackening caused by sulfurization can be easily removed.
