Does chlorine effect Calcite Blue Extra Marble?

Yes, chlorine can potentially damage Calcite Blue Extra Marble. Calcite Marble is composed primarily of calcium carbonate, which is susceptible to chemical reactions with acidic or basic substances. Chlorine is a strong oxidizing agent and can cause etching, discoloration, or even degradation of the marble surface if it comes in contact with it. It is therefore important to avoid using chlorine-based cleaners or exposing Calcite Blue Extra Marble to chlorine-containing substances.
