Which ultrasonic cleaner is best for steeping e-liquid?

Steeping e-liquid cannot be done in one of our personal ultrasonic cleaners. We recommend using the iSonic P4810 or another larger, professional ultrasonic cleaner. The personal models do not include a cooling fan, and thus cannot run for long periods of time without overheating. The P4810 can run for 30 minutes continuously without overheating; however, be sure to allow your cleaner to cool for about 10 minutes between every 30 minute cycle. The larger, professional ultrasonic cleaners provided by iSonic are also made with stacked transducers, which are twice as powerful compared to the wafer transducers found in the small personal models.
