I resize,deprime,clean primer pockets then trim if needed.
I then put brass in tumbler corncob media for a hour or so then reload.

Today I took some brass out of tumbler and noticed some of the media was stuck to the inside of the case.
Never happen to me before I assumed just old media?
I took a small allen wrench and lightly scraped the inside of case to release stuck media that wouldn't come out by just shaking .
I noticed some black/powder type residue that came out with the media?
Never thought about cleaning the inside of case?
This brass has been shot 4-7 times already.

How does most people on here clean brass ?
If inside how?
Is it necessary to clean inside of brass?

Thanks
