Go to Pattersons in Bristol, or your local wholesale supplier of
cleaning stuff to hotels etc. They have stuff far pokier than the
domestic retail grade.

Basically you want sulphamic acid to dissolve the scale. Hydrochloric
(brick acid, muriatic). will do this too, but is likely to develop
black crazing if the glaze was already invisibly less than perfect.
Sulphuric drain cleaner isn't much use on scale, but is useful on
blockages.

You shouldn't have any problem with heat, gas or explosions, but don't
mix cleaners or you can do.
