Brasso!!!???
Brasso contains Ammonia!!!
Ammonia will break down brass making it weaker. I saw a site advocating using brasso on bmg rounds and they said it had an immeterial effect on brass so I decided to test it myself.
They were wrong, and even with with 50 cal brass, the effects were a significent decrease in the strength of the necks.
I've been shooting bmg for years, and shinny brass in no way improves accuracy. Clean brass on the otherhand does. Tarnish marks on brass are just that, tarnish. Use your fingernails to determine if the brass is clean.
When I first started reloading my brass I wanted it to look new and shinny. I tumble my brass before priming and after all the milling processes to make match loads.. that means two sets of media.. one with polishing compund and one without. Easier just to tumble and use something like 'Goo-Gone' (petrolium based) and then wipe it off.
Polishing compounds also require another step: you have to clean that crap off before sizing. IMO, not worth the effort.
Flame as you will. I know there are two camps on this. Use polishing compund made from Dillons made for bullet brass, but NEVER anything that contains ammonia like brasso.
If you want to test this yourself, buy some brass from your local hardware store, cut into 1/2 inch strips and tumble it in your brasso mix. Clamp to a vice and see how many 90 degree bends it will take to break compared to the virgin strips... I guarantee you, you'll be with me after this test.
