When cleaning polished tiles it is recommended to sweep or vacuum the floor of all loose dirt, sand and other foreign materials prior to cleaning.
Mop the floor with a mild cleaning solution and water, using 50% less detergent concentrate than you would use on an unpolished floor.
Use a damp mop with clean water to remove any cleaning solution, then dry the floor thoroughly with a soft cloth or buffing pad to increase the shine and prevent water spots.
