I should mention that for those who want a magnetic stirrer but aren't willing to pay up for one, they're incredibly easy to build DIY style with a computer fan and some rare earth magnets. Superglue is your friend. YouTube has several examples and walk troughs. Also, you can buy the "spinbars" that go in the liquid from eBay for only a few dollars. My home built contraption works like a charm for under 20 bucks. Cheers!
I would love a magnetic stirrer, but I just can't justify spending $100+ to skip shaking. For $15 this could be a win. Hopefully we can get a pro to chime in!

just attach to a drill
I use cotton buds ( cotton removed and split the plastic ) in my dremel. Works a treat.
Disclaimer: this is just used for personal mixing and no you don't get cotton bits in the juice if you removed the cotton properly.
These devices are going to aerate your juice, as there isn't a way to incrementally adjust.
I'd recommend using an ultrasonic cleaner if you don't want to buck up and buy a magnetic stirrer.
just buy something like this
These actually work really well. I cut the tip off of one so that it is just a bar and fits in all of my smaller bottles. It gets them cloudy and well mixed after about 10 seconds even with the frother part removed.
