I was wondering what kind of media is suggested for cleaning your brass should it be sand or walnut or what is recommended

I think you can use walnut or corn cob. Never heard of using sand.

To get dirty brass clean I use walnut media.  Then, to put a nice polish on it I use corn cob media.  It comes out looking like new brass.

Walnut and Corn will both work. A lot of folks will add nu finish or other polishing compounds to make it look pretty.  They also make wet tumblers which work awesome and use steel media...but only in wet tumblers.

You can add liquid Brass O to the media. Add a couple tablespoons to it while it's running and let it dry then add your cases.

I only use Walnut media as it holds up better then anything else I have used.  It's the only thing I buy from Harbor Freight (made in usa), you can smell the communism when you walk in that place!  I have added stuff to it in the past, Dillon's polish, but I don't anymore.  I really don't care how shiny the brass is and I would be hesitant adding some polishes as there is some evidence that it can change the structure of the brass (weaken it).  For pistol rounds if you really have to have shiny you won't have a problem but for higher pressure rounds where you bumped the shoulder back a bit far, who knows?

There are a lot of youtube videos on tumbling media and methods.

I am fairly new to tumbling brass. Got a tumbler for Christmas in 2021. One of my presents was Lyman walnut media, to go along with the tumbler. It sure does a great job. If memory serves me well, the media already has polishing agents in it. It truly comes out with a shine better than new. Have a toothpick handy to get media out of the primer pocket, as some gets stuck in there. I highly recommend the Lyman product.

I used to use a mix of walnut and corn media but I now use small grain rice and have had better results.

For really clean brass go with a wet rotary tumbler.

Dry tumbling leaves a lot of contaminates on the brass.

Rice huh? Interesting!
I have a number of different ones, but untreated walnut would be my preferred.
One of my pre-treated ones has a reddish color and it clings to the cases. I dislike the reddish powder sticking to things.
My brass does not have to look new, just has to be clean.

I find that the rice actually absorbs most of the dust and residue that's normally left on the brass. I heard it from a few Pro F-class shooters and decided to give it a shot.

Unless you have old range brass skip the wet tumbler.  The pins remove carbon from inside necks and peen the case necks.  Both are bad.
