It's also possible that you've got some machine oil in there from somewhere. If the radiator wasn't properly flushed with solvent after its manufacture then after a few days running in the warm you probably managed to dislodge this gunge, which has then collected at the slowest running point of the system (res/header). Coating metal products in grease isn't uncommon, 'cos they then look shiny on the shelf whereas they might tarnish.
