Hi Everyone - Here's a simple question... :-) What methods do you guys use to clean 1/4" jacks? They're not really too crusty or anything, but I want to do some preventitive on them. I'm going the "insert the plug 50 times" route, but what else should I do? Should I use some type of cleaner? Is there a brush or tool I should use, or is that a bad idea? Thanks, Tim
