If you’ve got some dull, handed-down pieces of jewelry in your jewelry box, you can spiff them up to look like new by soaking them in a bowl of 5 oz of club soda to a few drops of dish liquid soap. Let sit at least 10 minutes then rinse off with warm water and dry with a soft cloth. The soap will have cleansed your pieces while the club soda’s carbonation loosed up built-up dirt and oils. Now they are ready to wear!
