Cleaning a header

[MM99lude]

Hey guys i just bought a used header for my lude and its a 4-2-1 2 piece... and i want to clean it up a little before i install it so i can hopefully get some smoother flow. Is there a special way that i need to clean it? i dont really wanna use water on the inside cuz i'm affraid of promoting rust. so any suggestions?

thanks

brake cleaner is good stuff for cleanin metal. or if you could find one, an acid tank, 20 minutes in there would make is brand spankin new.:thumbsup:

so maybe pour some brake cleaner in there then take an old rag or t-shirt put it on a stretched out wire hanger and run it through?

alright anything else i could do?
