muriatic acid and porcelain?
I'd like to have some smart advice, or a good pointer to some smart advice, about muriatic acid and porcelain.
I live in an area with high carbonate content in the water, and the toilets start to build up a tan-colored crust. A half cup of muriatic acid in the mostly drained bowl every few months does wonders for this. Cheap, easy, fast. But the question is whether this does long-term damage to the bowl porcelain.
The info on the web is concentrated in two strands. (1) muriatic acid is DANGEROUS!!!! Use with care!!!! (geez, I know ...), and (2) sure, it'll work. Neither addresses possible long-term damage to porcelain.
It may be that modern porcelain is more resistant than older porcelain.
