So I was gonna pick up some walnut hull at a local store tomorrow, 9lbs for $15 was all they had.
But before I did I thought I'd try something I'd heard which was throwing the brass in my rotary tumbler, some hot water, some tumbling shot and some liquid soap.
Took about 10 minutes and the brass looks fantastic... Seems almost too simple..
I know you can't use any liquid products with ammonia in them as that damages the brass, making it brittle, but is there anything I should look out for doing the above??
No ammonia in the soap ingredients.
I'm sold on the above unless someone would like to advise me to do otherwise
