We have perfectly fine old toilet, which works fine and has no

and when she uses the toilet during the night, more often than not, she
forgets to flush. This leaves her urine to sit and deposit/stain
until I wake next morning to make sure the commode is flushed. Over
time, this has caused heavy brown deposits (lime?) in the bottom of
our porcelain crapper. I've tried to keep up, but they jes keep
adding up and now even scrubbing with the new fangled hi-tech brushes
with disposable pads can't remove the most heavy stains. I tried some
Lime-Away, which cleaned up the lighter deposits, but the heavy darker
one's in the very bottom remain. Any suggestions on what might remove
these stains? Would muriatic acid be too much? Obviously, I don't
wanna destroy the smooth porcelain glaze.

If you can't wash it off without scrubbing with a Brillo pad or the like
the glaze is probably already deteriorated. I would just replace the
toilet if the stains bothered me that much.
