I got a bottle of the Harpic Limescale Remover the other day (the hard water here is a killer). It worked beautifully--our toilet bowl looks new. I thought to myself, "wonder how it works... bet it's acid" (I know from experience that half a lemon and some salt will do a reasonable job on limescale--the citric acid in the lemon reacts with the alkali in the limescale, and the salt is an i-forget-the-name-but-irritatting-rubbing-cleaning-thing to help remove it). Rather nasty doing it to the inside of the toilet bowl, though.)
Looked on the label and sure enough--"contains hydrochloric acid". No touching the toilet bowl, boys and girls! I bet this means that the regular "lime and grime" remover (for the tiles, etc) won't work nearly as well... I'll be back to the lemon and salt! (Meh. It works, but it's fiddly. And don't go eco-warrior on me and tell me that it's better for the environment than powerful chemicals. Unless you're prepared to put your principles to the test and do it for us. :) )
See, I may have failed Honours Chemistry I, but I do know some things :)
