Howdy,
I have had stains in the bottom of a toilet bowl in my property from pervious tenants and nothing seems to lift them..
In a foolish attempt to remove the stains I used caustic soda to attack the aforementioned stains.. this has now resulted in a hardened product in the bottom of the bowl.
2 questions, is this hardened substance dangerous and how do I go about removing it..Cheers
Age of property? (There is a good reason for asking).
Brick acid and a cold chisel
cold chisel, then a new bog?
Flush the bog a few times to get rid of any caustic soda residue, then put in a slosh of brick acid. Wait for an hour. Repeat if need be.
I would be very liberal with the brick acid. Just not necessarily in an older property with traditional drains.
The thing is that by the time its stopped fizzing there is no hydrochloric acid left - just calcium chloride. I did this with a bog once - the actual limescale was over an inch tick and the thing would barely flush.
Itr took half a dozen applications and breaking up te scale mechanically as well - I used a chisel, but no hammer :-)
Guess why when I rebuilt the house a water softener was considered essential
It sounds to me like the glaze is crazed and you are suffering grottyness in the cracks. Not a lot you can do except change the pan, or live with it. Brian
