How do I remove etching on limestone from cat urine?

Q: How can I remove etching that has formed on my Lagos Azul floor from cat urine? I cleaned it up pretty quickly but I see etching.

A: Etching is the result of any acid coming into contact with the stone. Unfortunately the only way to repair it is to repolish it. If it is etched too deeply it may need to be refinished. This will require the services of a professional. However, you may want to try a simple polishing cream for removing the etch first. These products can be found at available at Stone Care Central.
