If you do re-use polish, take precautions not to allow any contaminates(ie coarser grit) to get into the Polish slurry. Keep my polish slurry in a closed container. I always run the load to be polished in soap for 2 to 3 hours just before they go to polish to help remove any grit particles. For me I use Ivory Soap as it has no added chemicals that can be bad for the rubber lining in the barrels(or so I have been told)
Good luck

Most common polish used on this forum is Rock shed's aluminum oxide 14,000 polish. cheap and effective. jamesp, I have only ever gone up to 1,500 polish. I know this has been discussed, so I'm sorry for re-asking, but do you jump from 500 to 14,000, or are there other intermediate steps? I know in practice, you tend to let the grit break down over a longer period, so in essence it becomes those finer grits, but I would be interested in trying some 14,000, and I would like to do it right. Thanks! -Eric AO 500 to AO 14,000 was the way in the rotary and the vibe at one time Eric. If the AO 500 was run long enough in the vibe I got a fine polish and could almost skip the 14,000 run. For some odd reason I am having luck using AO 80(even AO 22 go figure) in the rotary or the vibe. And then doing AO 14,000 in the vibe for final polish. Have done about 10 runs using only AO 80 and AO 14,000. Been reliable. AO 22(extreme case) and AO 14,000 in the vibe: AO 22 in rotary, then 14,000: AO 22 in vibe, then 14,000:

Until a few months ago, I would go from 500 SiC (48 hours or so) straight to 14k AO. Once I added a 1000 AO step in between, the difference was quite noticeable. Enough to make me want to re-tumble everything that I had completed prior to that change. I am intrigued by the 80 AO method and will plan on trying that once i need to reorder grit. I think the SiC 500 step is a backward move. SiC is just not known for it's ability to smooth. It cuts. if you substitute AO 500 you would be pleasantly surprised.
