For a while now I've been using abrasive paste on my pieces I can spin (hollow forms, traditional bowls, plates and platters) and really like the outcome. There are lots of discussions here about using sanding sealer, not using, types of pastes, DIY, etc. I don't use sanding sealer. All I see here and online say to spin with a clean towel until it stays clean. A while back I started using the grey scotchbrite pads to do a final cleanup after the towel was coming up clean and I get a LOT of thick residue that still comes off. I keep going until the scotchbrite pad comes up mostly clean as well. The look and feel seem better to me and I feel better about getting as much of the residue off as I can before I apply a finish. Usually walnut oil or danish oil. Not sure if doing this final cleanup is warranted or really makes a difference but makes me feel better to not have that much of the abrasive paste residue under whatever finish I choose.
