By request, at least one person asked ^-^ Here's a recipe I found that person said was from a 1957 NRA article. He said it works good for black powder also in the post I found so someone may want to try it for that.
**WARNING** If you don't like the smell of vinegar, this is NOT for you. ^-^
1 Pint water
1 cup white vinegar
1 tablespoon salt
1 teaspoon dish detergent
Also find a med size platic tub with a lid, at least thats what I use I'm sure there are many ways to do this, this is just what I do. My tub is 48 0z/3 lb tub that held cookie dough. Hey we had to make the cookies and eat em first for me to get the tub, who says dyi doesn't have benefits? Here are the things needed.
Here's the brass before washing.
Pour all ingredients in tub and give it a quick stir to mix, I just put the dish soap in last and stir with that spoon.
Then dump that dirty stuff in...
And seal it up..
Now the recipe said to wash for 10 mins, I just set kitchen timer and go. The reason I use a tub with lid is I just swish it in my hands tumble it end over end etc for the 10 mins. Here's the cleaner in full soapy mode, I take the lid off occasionally and stir with my hands too. Also lets you see how the cleaning is coming along.
When the timer goes off, its time to rinse for 10 mins also. Just set timer again and start rinsing. I use warmish water in all steps cause my hands are in there.
While rinsing I dump water and refill several times. I do the rinse like the wash agitate by hand tumble end over end etc.
When the rinse timer is up I dump as much water out as I can then dump brass onto waiting paper towel. I then gather towel around brass and give a little squeeze to get excess water off.
Then I transfer brass to the lid on a towel to air dry. One could also dry in sun,or a low 150 degree oven. I'm not in a time rush because I clean batches well before I'm going to load, usually when I collect 50. I clean 50 at a time just because thats what fits in the empty ammo trays I use for reloading and also that amount seems to fit and clean well in the tub I use.
Then as the final step which I do while checking case length I lock each case in the cutter stud with shell holder and give it a final buff with fine steel wool
Well thats all there is to it, wash and rinse process takes 20 mins. Dry time depends on method you decide to use. Try it especially if you don't have a tumbler which is why I hunted for something I could make instead of buying chemical liquid case cleaner.
