I de-prime all brass first. Some cartridges can get washed with others. Some, not so much. I will de-prime brass when I come home from the range and throw it in the wash container for storage.
When I have a decent amount of brass to wash, I fill the container with warm water, one drop of dawn, and no more than a table spoon of Lemi Shine.
I wash the brass 2-3 hours. This depends on the amount of brass to be washed.
Once complete, I drain most of the water. Next, I dump all the brass and pins into a rotating sifter/media separator. Once the pins are separated from the brass, I rinse in my kitchen sink with the dish sprayer very well. I'll shake the media separator very well to remove as much water as possible.
The last step is drying. Here, I use old toaster oven cookie sheets and align them like dominos sitting straight up on the head stamp. I then throw them into my electric smoker with no wood chips at 170 degrees for about an hour. I'll check the primer pockets after the hour. If they're still wet I let them dry more, otherwise they come out.
I used to have issues with water spots and I found the key was to use as little dawn and lemmi shine as possible and rinse the brass well.
