Being in a hard water area the u-bend of the WC bowl gets a coating of chalk

Pumice Stone seems to scrape it off quite well without damaging the glaze of
the chinaware.

Is there a good way that anybody has found to attach pumice to something to
enable it to reach right into the bend?

Thats a hard way to get it off. Almost any dilute acid will take it
off. I use CLR, dilute muratic acid, or even a liter of cola poured in
and left over night will remove it. Using the pumice stone will
scratch the surface and make the next accumulation that much more
difficult to get off.
