Hey guys I have a price of brass that's been through alot and means alot to me however its really dirty. I washed it in soap and water then I rubbed it A TON with a green side of a sponge and that took alot odirt off however there was some parts the might of been crooded? I loomed it up online and they said to rub katchup on it and believe it or not it worked.but there's still some there.also any help in telling me how to get the brass to really shine. Rember that its only one casing so I don't wanna buy a big machine.
