Help. Getting into reloading.

[CINDERS]

Tried sonic its okay if you want sparkly brass inside and out but can be fiddly and I use demineralised water as suggested probably sonic every third firing, I agree with Bruce you have to wipe the dust off them I have gone away from pads and am now using Hornady one shot spray can job works well I coat up to 50-60 rounds at a time roll em around on the tin lid where I spray them and away you go the expander ball does not gall either just be judicious how much you get into the necks.
