I'm with Kitsie! (In fact, I believe I may be the one who told her about it!) When we used to visit my father-in-law in Tucson his shower head was all but unusable. My husband wanted to replace it for him but I remembered an HGTV ad that said 'the same thing you clean your dentures with will clean your shower head'. It worked so well that we laughed, laughed about it at the time.
