I unknowingly had a small screw or nut fall down into a corny keg that i was using to store star san. after a few weeks i emptied the star san and noticed the nut had rusted and left a bit of rust on the bottom of my corny. i soaked it in oxy clean for a while. my arms are too big to get in to the bottom but i had the wife scrub at it. most of it came out but there was still a small nut "imprint" and a few spots. i 'm sure this wont be the first case of a bit of rust coming into contact with some beer but i was just wondering if anyone knew if this could cause a problem? after i drink the nut brown i just kegged i'll have the wife take another crack at scrubbing it outta there. any suggestions on cleaning it?
Thanks in advance for the help.
