Remove urine stone
I've really tried everything before to remove the brown urine stone from our toilet: citric acid with and without baking soda, cola with and without baking soda, vinegar cleaner, special cleaners from the drugstore, etc.
But my friend has it by chance when cleaning - yes, he once cleaned the toilet by himself - get away easily, with mold remover! He probably only allowed to act for an hour and everything was again sparkling!
I can only recommend this to anyone! Ours was from Sagrotan, but will certainly work with other brands as well.
