Re: HELP! My hookah is sick!!!
Brass doesn't rust, it corrodes. Go buy some Wrights brass polish and go to town. Just a warning though, it will come out black as night.
It would be best to also purchase a shotgun cleaning rod. Apply the Wrights to a folded piece of paper towel (attached to the cleaning rod).
Wrights is water soluble, so it will clean out really easy.
I use this occasionally to polish my brass trombone slide.
