• Self cleaning effect is needed two properties that decomposed effect and hydrophilic effect.
  • Self cleaning effect is mixed decomposed effect and hydrophilic properties. Some mold and bacterial are cleared away by decomposed effect. However put on some blot, air pollutant-formation or bird dropping are keep down to adhesion condition by decomposed, then hydrophilic property is cleared way with rain water.
  • Only either property is not able to do self cleaning effect.
  • Photocatalysis self cleaning effect  is the only ticket.
