Oh for heaven's sake - you guys! When was the last time you heard of someone dying a painful death due to - shock horror- a dirty mouthpiece?
The best advice is to run fast flowing cold water through it and then dry with a fresh piece of kitchen roll.
Antibacterial wipes/solutions will simply remove the weaker bacteria and leave the super strong bugs still clinging to the plastic.
I've had loads of second hand mouthpieces for years, have never done more than swab them and never had a problem!

Turned several shades lighter, but amazingly still worked, as far as i know...
The boy or the mouthpiece?
