Eliminare il giallore dell'argento

I found this very interesting video that explains how we can remove the annoying change of color that has the silver. The color change is due to silver sulfide which is in contact with the sulfide d 'hydrogen, and reaction to form a thin layer of this material that makes losing shine to our jewelry.
The video is in English, but as you will see is very simple, you only need hot water, baking soda, salt and an aluminum pan. But where the yellowness
end ???.... she will take our aluminum pan!
