Plastic, Picnic Style, Liquid Dispenser Tap

Q: Clean or replace a picnic tap? A: Replace!

Q: How can you thoroughly clean and sterilize old picnic taps? A: You can't. New picnic taps are inexpensive. Don't be stupid and use an old picnic tap that risks contaminating the homebrew that you've spent hours and $$s to make and, perhaps, even bottle for a competition.
