This might sound bad. I have 4 kegs and just use one picnic tap that I pull on and off. I clean it every once in a while =)
The first time I disassembled the tap and QD I was amazed (and grossed out!) by what was in there.
I've been known to switch them right to the new keg. But Denny and Martin are correct, there's some nasty stuff what can grow in a picnic tap. I did not realize it until I served a pint with a floating chunk of nasty in it.
I try to be good and change the lines with every keg. Mostly, I will rinse them out and sanitize them regularly and give them a good soak in oxy clean once in a while. I have a large handful of picnic taps, so I can change the plunger/stopper part pretty regularly. IME, that's where the nasty grows.
If you disassemble your QDs, be careful. There are o-rings and other parts that can go right down the drain.
