hey all

i have this huge brass piece (or at least i think its brass) that has a bunch of fingerprints and smudges on it. i tried cleaning it with a wet towel but that doesn't do much. any suggestions on products or techniques? i know ATOT is a diverse crowd... someone's bound to know the secrets of life

thanks

I think you can buy cleaning solution for that.

More info on what exactly this is? Does it have a natural patina, or what?

If it's just general dirt and fingerprints, an alcohol soaked terrycloth should work well.....

Brasso is your friend

it's an ammo shell... a really really big one.

Brasso works wonders. We went through the stuff like it was water when I was in the Army. Used it for cleaning belt buckles, insignia, doorknobs, plumbing fixtures, etc.

You could try vinegar too.

I used a dremel and a polishing head and polishing compound to polish an old 50mm shell casing... might want to laquer it, because it tarnished in like a month.

Just never use bleach, it's highly corrossive.

Ummm - brass polish. You can buy it at lowes and stuff.

I think ketchup would work, since it is high in acids. It works on copper, atleast.

Mix HCl and HNO3 in 4M solutions, works great on gold as well.

all great suggestions

nevrdull, vinegar, ketchup, dremel, even what biostud said... i'll have to look up those mixes... not sure what they are.

thanks all... i think i'll try each and every one of those techniques... maybe i'll make a "results" post to see which one worked the best.

thanks again
