WHAT THIS IS FOR
Polishing cloth removes tarnish from sterling silver jewelry and flatware. The cloth is impregnated with jeweler's rouge (an extremely fine polishing compound). You can use the jewelry polishing cloth without fear of harming semi-precious or precious stones,shell beads,crystal, or whatever else might be a part of your jewelry besides the precious metals
HOW TO USE
Simply draw the chain gently through the folded cloth and repeat until the tarnish is removed. The jewelry polishing cloth will eventually look rather ratty and blackened, but it will continue to work until it is literally worn to threads, so it will last for a very long time.
