I see some confusion betwixt Group A Strep and GBS in some posts... Both Gram Positive, but very different classes of bugs. Regardless, when it comes time for me to clean something possibly infectious with a typical Gram Positive like that - I'm going to the Lysol every time. Alcohol is great in a pinch, but Lysol, evap, wipe, alcohol dip is so close to 100% that it's not even worth thinkin' bout.
That said - I don't think you're going to effectively disinfect that batting without destroying it. Toss 'em. They're disposable. Disinfect your batteries with Lysol, but don't let it run into the battery guts.
(And I believe you're looking for "nosocomial", not "non-socomial" (NOT in a hospital) or "nonsocial". Not picking on you or anything [really!] - people will probably just find it easier to look up with the correction. I knew what you meant.
