General maintenance and cleaning of porcelain tile will vary depending on the surface and soil load. General cleaning should be performed first by sweeping or vacuuming to remove loose soil or other surface contaminants, and then lightly damp mopping with clean water.
Depending on the soil load, a more aggressive cleaning process may be required. This would include the use of a neutral cleaner or a general household cleaner, followed by a through rinsing.
