How about non-stick tiles and grout?  EnduroShield’s revolutionary Tile & Grout Sealer makes grime, dirt and mineral deposits easier to clean.  Tile and grout are porous and as a result absorb mineral deposits, soap scum, body fats and grime making the surface very difficult to clean.  Overtime it can discolor and look unsightly.  The repellent nature of EnduroShield provides the protection of a general grout sealer but will also repel water and oil-based stains.  No longer is scrubbing with harsh toxic cleaners needed, EnduroShield makes cleaning a breeze.
