Just curiou... How much did you save buying the Lizzard Litter, wax and mineral spirits vs. just buying a box of Lyman red or green polishing media? Seems to me if would just be a heck of a lot easier to use one product instead of three.

Lizard Litter was about 7 bucks for a 10lb bag and Nufinish was 4 bucks and Mineral spirits were like another 4 bucks. So was like 15 bucks total

I would just get the lyman red stuff for 8-9 bucks for a 7lb tub, I get about a years worth per jug and my tumbler runs about 30 hours a week

I use walnut and put a cap or two of the blue stuff Dillon sells in. I do not think you want to wax the brass, just clean them. I would guess the mineral spirits would evaporate and leave a petroleum residue behind. That might contaminant the powder or primers.

Brass nice and shiny not greasy at all. I let the Nufinish and mineral spirits mix for like 30 mins till it was basically dry came out real nice

I just use the pre-mixed media. When it starts doing a shitty job or takes forever I will pour a cap of nu-finish or Flitz in the tumbler.

I always throw a used dryer sheet that has been cut up in to strips or small pieces in with the media as well. It traps all the fine particles and keeps the media working longer and catches a lot of the nasties from going in to the air.

I don't even bother tumbling.

Shiny brass gives away your location; therefore shiny brass is not tactical brass :wink:

I just tumble enough to clean the brass. Not polish.

Nufinish is a common trick, just toss a capful in every couple batches. No need to let it run for 20 minutes before adding the brass, it will work in just fine if you add the nufinish in at the same time as the brass. Never heard of the mineral spirits though.

Honestly, I just wash all of my decapped cases in a plastic tray filled with soapy water. Lay all the cases down (orient them so they are all facing the direction the water will flow), and tilt the tray back & forth. Pulls an amazing amount of crud from 2x/3x fired cases, and gets all the crap off of them.

Then do two rinses (first one gets most of it out, second one takes care of it all) & voila, now you can lay it out on a paper towel for a couple hours. I prep my primer pockets at this stage while it's still drying, and the crud is still soft.

I know some people that swear by something like that to preclean before polishing. They put the brass in a big rubbermaid bowl with a lid. Then the add hot tap water, a squirt of dish soap, and a spoonful of this stuff called "lemi-shine" which appears to be some sort of citrus based dishwasher additive. Anyway, put the lid on, and shake the crap out of the mixture. Let soak for like 8-10hrs shaking every few hours if you can. Then rinse the bras well and lay out to dry. After the brass is dry, then add it to the polisher. Seems like a lot of extra work to me, but I guess the polishing media lasts longer.
