@Xelatsok , I love how one of these Nomands made it all the way out to Siberia... pretty cool age we live in! Great lookin' avatar! @Hogni , Not too sure about those glass fiber abrasive sticks... looks a bit...harsh.. but It might be worth a try! I think that one of those pencil-style erasers, that come with long re-fillable eraser sticks... would work really nicely. Pencil erasers seem to have a pretty good reputation for cleaning electrical contacts. @HerbieVonVapster , HAHA! What a hilarious image. glad you made it back home safe. Our mailbox is down a very steep hill... so I know your pain... we have a heat wave here as well... so... forget about checking the damn mail. Not to mention that our mailbox gets destroyed probably about three times a year for unknown reasons.... it's kinda hangin' on be a thread at the moment.
