Thread: Newbie question - cleaning brass with tumblers / ultrasonic?

To only clean small amount, say, up to 30 223 cases I use an Aldi ultrasonic cleaner. Sold as a jewellery cleaner. Cheap and cheerful.
Hot water + about 25% of Vinegar along with a squirt of dish washing liquid.
I deprime first to save cleaning the primer pockets. About 4 minutes will do the trick. Rinse well afterwards. If you like add a little bicarb to the rinse water.
I just dry them outside in the sun/breeze.
