Using brass polish in my tumbler?

Post by dustin » 08 Jul 2013, 4:13 pm

Hi All,

Someone told me that I should use a little brasso polish or something similar in my tumbler.

Does that sound like the way to go?

Thanks.

Not sure why you would? Standard tumbler medium does a fine job.

There is softer and harder medium, if you've got particularly dirty brass just make sure you use a hard medium in your tumbler and it will be fine.

If anything brass polish would probably weaken your cases over time and just gunk up your tumbler a little?

Some polishes will weaken the cases. Ammonia for examples will dissolve the copper portion of brass alloy.

Normally this wouldn't matter if you're polishing candle holders or whatever your household stuff is, but when you're doing it to cases which have to withstand 50-60,000 psi upon firing... I'm certainly not keen on the idea of contributing any potential weakness to the process.

Standard medium works fine, as mention above, maybe just try some harder medium if you're doing really dirty cases. Outside of that, if it aint broke don't fix it.

I've put what must be thousands of rounds down range with regular old tumbling.

I wouldn't bother mucking around with anything else in the tumbler as the usual method works perfect for me.

Thanks all.

Won't be using polish in the tumbler. Put through a hundred brass earlier without it and it came out brilliant as is :D

Yep, absolutely no need for anything more than standard tumbler medium IMO.

I use the hard "Turbo Tufnut" media from Lyman, and all my brass comes out as sparkling as it was when it was new.

I've tumbled a few loads of brass since and got the same result - all clean!
