Is the pure&clean™ Surface Prep safe to use and not cause damage to to marble counters?

Yes, all pure@clean™ Vision products are safe for use on marble countertops. The HOCL in our pure@clean™ products is likely weaker than the cleaning products your’re already using and certainly weaker than vinegar which is documented as a disinfectant by the Marble Institute of America.  Also, the HOCL is fully effective in seconds, so you can spray and quickly wipe off to limit absorption in the marble.  For more natural stone care information, please visit ‘A Guide to Care and Cleaning of Natural Stone‘.
