How to clean outdoor tiles
Sweep the tiles daily.
Try to sweep your porcelain tiles every day or so. Use a soft, natural bristle broom or take a vacuum attachment and suck up the dirt.
Regular sweeping will prevent your tiles from becoming caked with dirt and stained. If your porcelain tiles lead up to an entryway for your house, you'll want to sweep them more often.
