I pulled water-pik out of the closet today, which I hadn't used since
I moved a little over a year ago. I cleaned it first with bleach, then
with vinegar, according to instructions posted on this newsgroup. Both
times I ran about a gallon of water through it to get rid of the
cleaning agents.

Several hours later, I grabbed the hose to shake out any water inside,
and some drops came out. These water droplets had little black specks
in them! I don't know if this is gunk from inside the hoses or pieces
of dissolved rubber. Either way, I'm not sure I want to use this thing
again. I was never very good about cleaning it before. Has anyone else
had this experience? Should I throw it away?

It worked wonders for me in the past, even though I found it to be a
bit less convenient than the bottle irrigator I use regularly now.

Thanks,
Rob
