It depends on how you use it. As a cleaning product, the
carbonate would stay in solution.

Until you dispose of it.

It either stays in solution or precipitates out as a solid.
There is not a direct path back to CO2 without some outside process.


The Chemical formula is

CO2 + Ca(OH)2 - -> CaCO3 + H2O

It is not a reversible Process. But adding lime to water containing carbon
dioxide will precipitate Calcium Carbonate as a solid, leaving pure water
behind. The amount of lime required to remove carbon dioxide is around
10-15 mg/liter.

Better living through chemistry, as they say. I bet there is some nut
somewhere that has discovered "true chemistry", though.
