BPJ Foam Cleaner by Lavish can be used daily, or any time that your jewelry needs cleaned. The foam gets into the hard to reach places and breaks down the grime so it can be easily rinsed away. Say goodbye the lotion, body oils, and other gunk that gets in the way of your sparkle and shine. This product can remove mild to moderate tarnish from silver. For heavily tarnished jewelry, a polishing cloth and professional polishing is recommended. You can maintain your silver after the heavier tarnish is removed by using Lavish regularly to prevent further tarnish. Soak 10-30 seconds for the foam or pen then rinse. Soak no more than a few minutes in the jewelry bath before rinsing.
