Cutting off the water supply, draining the tank and spraying the seat with vinegar or CLR does the same thing -dissolving the calcium carbonate. You can prevent calcium carbonate buildup by putting a piece of magnesium in the tank.

You may use a calcium remover for toilets. If you have patience and willingness, you can make a DIY toilet cleaner composed of vinegar, lemon, other acidic liquids, and baking soda. Thick calcium deposits in the toilet require muriatic acid and deep scrubbing with scour paper.
