I don't do
When bio hazards are involved I usually tell people to go clean their guitars and then bring it back for repair.
Still not as disgusting as this.
One time a guy came into the shop wanting his bass setup.
He attempted to pull it from a very nasty an filthy gig bag. He got the bass half way out of the bag. When 3 cockroaches jumped off the head stock and onto the floor.
Even they didn't want to be on that bass. LOL.
Nope. Take that thing out of the store fella.
A good rule of a guitar tech/luthier.
NEVER/EVER turn an acoustic guitar upside down over your head and try and shake out something that is in it.
The worst things fall out of acoustic guitars.
