I have one and I only handle it when I am cleaning my shower. Coincidentally, I cleaned my shower head last month as more than a few ports had clogged up. I soaked it in vinegar for an hour, pushed a pin through the calcium encrusted ports and scrubbed it with an old, HARD bristled toothbrush. No crustaceans were observed. One note: Hard bristled toothbrushes(stiffer than 'Firm') are THE BEST for cleaning small parts. Not so good for brushing your teeth unless you don't like enamel.
