I bought this after reading the fave reviews from many others. Out of sheer curiosity, I decided to buy one to try. I managed to try it on my silvers just recently and found it to be effective. There are two layers to the cloth, the exterior being the blue one and the interior being the white. The white piece is the one that is treated with chemicals. The blue for polishing. The design of the cloth is good because of the arrangement of the cloths: it keeps your hands far less dirty than you would to use just the white cloth itself. You need only to gently rub the pieces to see the stains on the cloth. I think with technique, this cloth could do better. Very good value for money and definitely clever.
