Re-setting up 1960s McIntosh system to 1980s Heresy II speakers. Q1: Removed Heresy grills & speakers are covered with dust/dirt. What should be used to ever-so-gently clean them? Used a micro vacuum gently, but they are still needing actual cleaning. Q2: How to get behind the speakers to clean it all out (the back of the speakers I mean as well)? Q3: Have a crackle sound (almost like a loose wire but not) so maybe the cleaning will help. ANY helpful ideas are truly appreciated. Can't wait to get back up and running! Thanks for your help!
