Years of working in restaurants teach you a few things. This one has been worth its weight in gold by saving time and huge amounts of dollars not spent doing this by hand or buying name brand chemicals that do the same thing.
Line a bowl with tin foil.
Add kosher salt and baking soda.
Pour boiling water into the bowl.
Place tarnished silverware (this is silver-plated) in bowl making sure each piece is in contact with the foil.
Watch the magic happen!!
After a few minutes, remove the silver from the water, rinse with cold water and dry with a cotton towel.
