Hi Bill,
You still lurk here? Anyway, the thing I've found works after the fact is beer line cleaner. It's designed to clean the tap lines of beer stone and slime between kegs. It does remove the slime and stuff, but you'll still have to flush the system to get the bits out. It doesn't dissolve the slime, but I'm not sure I'd want that stuff circulating in my water system anyway. It is safe for metal and hoses.

Cheers,

Bob
