I actually started with exactly that setup. I found that it did a pretty good job until those spinny jars failed. I was using the L&R Fluids, plus a few other steps for drying at the time, which made a big difference (particularly the cleaning fluid).
As far as cleaning with the balance jewels in place: i do this 😁 I realize many say to remove them, but I had it damage the balance staff 2x, so now I don't. I find that the cleaning fluid gets into the jewels 'well enough' that the stems are cleaned, and when I pull the jewels to epilam them, they are typically super clean.
