My band headlined at a bigger show for the first time a couple weeks ago and we left our mics, guitars, etc up there. The bands that played before us used our mics, and i was really uncomftrable singing that night. i had to make sure my mouth wasn't touching the mic because i didn't wanna get germs or herpes. How would one clean the grill, and any suggestions for next time we're headlining so my mic won't be used? I'm kind of a germaphobe
