I have even tried emptying the bowl and soaking the bowl with an entire container of CLR overnight. It didn't work. But, gently rubbing a wet pumice stone on the bowl surface will remove the calcium build up in a few minutes. If you are afraid of scratching the bowl, then don't use it, but it works for me.
