Oh, and Pinky, the one drawback to a pumice stone is that the first time you use it, you're going to notice a big difference between the areas you've scrubbed and those you haven't, especially if you have hard water. It becomes readily apparent that the hard water even dulls the surface of the parts that are always underwater, so you're going to go nuts with the thing on the first go 'round! You may spend more than hour on the toilet, but the end result will be incredible! A tip. Pour a bucket of water into the toilet bowl before starting. This will drain the bowl without it refilling, so you won't be trying to clean it all inside the water. But, make sure you keep the pumice stone wet as you're using it, for best results.
