Can I use an ultrasonic cleaner to clean silverware? Should I use a heater for this purpose?
Yes, you can definitely clean silverware in an ultrasonic cleaner. We recommend using one of our Commercial models such as the P4820 or larger. You may use the heater function as well, to achieve better results. If you need to remove silver tarnish from silverware, you must use iSonic Ultrasonic Silver Tarnish Remover to do so. We also recommend using a beaker or a plastic cup when using iSonic Ultrasonic Silver Tarnish Remover in any of our ultrasonic cleaners, as this particular solution will create a dull coating on the cleaner's stainless steel tank.
