Ultrasonic Steeping? (confused)

[therealameno]

Merry Christmas all!!!

I recently purchased an ultrasonic cleaner to test on my recently mixed juices.
After researching and watching many videos, you would usually see lots of bubbles go crazy inside the bottle.
I don't see any bubbles ^^. I am currently using this model.

None of my juices have changed in color after 1 hour of use.

Am i doing something wrong or do I really have to get a professional ultrasonic? I am using 15ml glass bottles with the dropper lids and have 3 in at the moment.

Any tips?

Ultrasonic sound waves make the air/bubbles go around in a crazy way, it might help to produce some bubbles to start with by shaking the bottle up OR using a milk frother to get it nice and frothy with air particles before sticking it into the cleaner.

I would also say that the quality of the ultrasonic cleaner has a role in this.

In my experience the bottles should be sitting in the supplied tray, not touching the bottom. If you rest the bottles on the bottom it stops the vibrations moving through the water properly and kills the whole effect.
I got a little industrial one that's really loud, I wouldn't say there were a lot of bubbles though. Half an hour in warm water and the juice changes several shades.

Heat and agitation are what speed up 'steeping', lots of different ways to get there
