I don't think I have seen anyone mention this, but one time I did add too much solvent, on accident, and it cut down on the dust (to almost nothing airborne) and thinned the Brasso a bit when tumbling with just cob.
My lady is allergic to walnuts, pecans, peanuts, but you get the picture... so walnut is a no-go, so I have to just use cob.
I have been doing this on purpose ever since, I just add enough to where the whole bowl is nice and moist, not wet-wet where it clumps and my brass has been turning out very nice, for just cob.
The solvent (most decently denatured alcohol), mixed with a bit of Brasso wets and buffs carbon off, and sort of polishes cases. Not mirror, but much better than just a bit...
I just thought I'd mention this, as my brass was not so clean initially, with minimal Brasso and solvent until I moistened it up more than I thought I needed... and no dust!
(Don't knock Brasso, some have been tumbling with it for over 30 years w/no ill effects.)
I need to try Nu polish, but haven't gotten to it... yet, and I am not going to go to wet-tumbling, so this is for the vibratory users, and no chance of stainless pins going down my barrels.
