If you own some of our silver pieces, they can tarnish with humidity, oils, sweat or body lotions.  We recommend the following solutions: Purchase a sterling silver polishing cloth (they are inexpensive and will last you a long time) and gently wipe your pieces with it. Place a square piece of aluminum foil in a bowl, place your sterling silver Magal pieces on it and pour hot (but not boiling) water in the bowl. Add a spoon or two of baking soda in the bowl and mix around. You can leave the jewelery in for about 30 minutes, then rinse off and dry with a towel.
