Hi,
Ney makes an ultrasonic of fairly large size that has dual
transducers that put out both low and hi frequency and
additionally it has a heater switch. They are good value for the
dollar. I have had one for the last 5 yrs. L&R makes a small
unit that dentists use chair side that costs about $100.00. I
have one of these too, no heater, but it works like a charm.
Spic and Span works great in the ultrasonics. It cuts tripoli,
sure-shine, white diamond, rouge et al very quickly without
ammonia.
