Cleaning cases

[perentie]

Well for those that read this thread.

I have the old girl shooting quite well now but at 79 its me thats getting to be a bit of a problem.
Anyway, what are the latest ideas on cleaning cases?
I have been trying several dishwashing fluids in my rotary tumbler with SS pins and the outsides come up shiny but I cant get the inside as clean.
, even though I use a drill and nylon brush before tumbling.
I know it does not make much (if any) difference to the way it shoots but its just me.
Thought there might be some new fluid on the market I have not tried yet.

Try adding some vinegar

I've noticed if l back off the charge of brass to a quarter of max you have a better nside clean. A teaspoon of white vinegar may help as well with the detergent.

I will try the vinegar next time. I have 10 cases in now I shot off yesterday and I put a tablespoon of citric acid powder in to try. I normally let them tumble for about 3 hours.

Ditto to that advice.

Its a gemstone tumbler. I dont know what the max charge of brass would be , but I only put about 25 to 30 in at one time.
