As you already know, I already have!
What I thought was a small pile of dead leaves, turned out to be a mummified mouse. I used a carboy brush, flushed it with water, rinsed with a jet sprayer, then cleaned with A one cleanser (like oxyclean). I didn't sanitize because, at the time, I thought the A one was a sanitizer, and my beer still came out OK with no contamination. I have since found Star San and love the stuff. I've had a batch of Ed Wort's Apfelwein in it now for about a month since the beer and it's showing no signs of contamination.
Go for it.:rockin:
