Hey all, has anyone heard of a product that can be added to the tumbler media to assist in polishing the shells. I remember Midway made some blue liquid stuff, but have not seen it for ages. If anyone knows of a similar product, please let me know.

Cheers Haemish

YES brasso or silvo works great but mix in before you add the shells as it can bog up inside the shells, any one else used anything as good or better ?

I got a liquid much like brasso from Sinclairs.
I think it was called Roosterbrite.
It has worked well at rejuvenating my old walnut media.

A few teaspoonsfull of brasso to a barrel of not too fine sawdust works OK in a tumbler. I am sure there are other options that may work better but its been our clubs standby for 15 years.

I have used Basso and a dash of car polish as an additive ( about 1/2 teaspoon of basso and 1/8 teaspoon of car polish ) in 1 kilo of corn media .. it works very well , clean .. VERY shiny inside and out and the polish seems to help seal the brass .. it feels smooth and tends not to get as dirty . I was told however that Basso has ammonia in it and can cause brass embitterment *** don,t know if this is true or not *** perhaps a metal polish without ammonia is the better option

I was a bit concerned about the ammonia in brasso, i do know it can corrode the metal after a while. If there was another mild abrasive in solution out there. I suppose even toothpate would work to an extent, nice minty shells! the misdway stuff was great. All suggestions are welcome!

I've had best results from using Brasso. I put it in with corn cob and let it tumble for a while until mixed through then let it sit for a few days for any ammonia to evaporate off before adding brass. I'm not sure if it makes any difference but it make me feel better.

I've also used Nu-Finish car polish. I believe it doesn't contain ammonia and can be diluted with white spirits if it's too thick to add to the media to get it to mix through.

Sometimes just a capfull of white spirits is enough to re-mobilise the abrasive in the media (not too much or the media will clump up). I find this also makes the carbon residue stick to the inside of the plastic tumbler bowl (Lyman) which I wipe out with paper towels and white spirits when it builds up. Keeps the media clean and the brass shiny

Thanks everyone. I did a little experiment over the last week with a number of different abrasives to see how they went.
Toothpaste - watered down to form a thin paste, a bit thinner than yoghurt. Did the job.... eventually. Too slow, you really shouldn't need to tumble for 3 days. It may just have been the media itself doing the polishing. However, cases di have a minty freshness!
Brasso/Silvo - Good, did the job. The ammonia smell didn't really go away though. Did leave a bit of a powdery residue on the cases.
Car Polish(kitten no2) - No 1!! i mixed some with water to make a yoghurt paste. Gave a great polish, little smell and quick!!

Something i found on the 6br forum was the use of a liquid solven to loosen up built up fouling inside the cases. It was 50/50 mix of white vinegar and water and a drop of dish washing liqid. It was designed to be used with an ultrasonic cleaner,but i left the caases to soak for an hour. Giving them a bit of a shake every now and then to loosen the crud more. I took them out let them stand to dry slightly, 20mins, then threw them in the tumbler. Removed more rubbish from the inside than tumbling alone, almost new looking, well new for a 7 times fired case!

Worth a try, it's amazing what happens when you try stuff that is not designed for shooting... works better!!!
