depending on where you are is the measure for lemishine. I get my water from a drilled well (almost pristine water), there is just a dash of maganise in the water so, I only use 1/4 of a teaspoon of lemishine with 1/2 teaspoon of dawn. Any more lemishine and my brass develops a pink sheen, if you notice that pink sheen back off a little lemishine.
I run it a full 3 hours then I have a "Frankfort arsenal media separator", witch can be got from Amazon. I dump the tumbler into the bottom then pour out the water and rinse ,,, now I put the basket in the notch in the top and pour the works into the basket, let it drain. The basket goes over to the bottom I then using a magnet to trasfere the pins to the tumbler. Back to the basket, it goes over to the bottom,, fill the bottom with water, cover and rotate back and forth for a minite or 2 this will let the water inside the brass knocking out the pins and they sink . Put the basket over to the top again and transfere the pins from the water in the bottom back to the tumbler. To dry, in the summer I spread the brass out on the picnic table and let the sun do it,, in the heating season after towelling I stand them up in groups of 4 on the wood stove ( 10 groups on then remove them in the order of first on first off )
