I've finally got enough odds and ends to fill a canister, but as you'd expect most of them are butt ends and weird bits that have a lot of scale and odd folds and stuff like that. I've ground them as clean as I can, but there are still pockets of scale on pretty much every piece. Is there any good way (short of something like sandblasting) to clean these? Is it super important that I do? I was thinking I'd put a piece of HC monosteel in the center of the can for edge-holding purposes.
