Never thought about using Goo Off. Will have to give that a try in the future!

If not using 100% acetone. I am using Goof-Off which has some acetone in it, but not 100%. I tested it out on an area of the mic that wasn't visible before I started and it showed no signs that it was melting the plastic, so we're all good here. Thanks for the suggestions. I nice citrus scent would be way nicer than the goof-off smell!
