Deck Cleaning in Arizona

What Arizona weather and trees do to a deck

Strong sun and dry air across Arizona gray and dry out wood quickly, leaving exposed boards weak and brittle. Keep air moving under the wood by sweeping away debris from corners and gaps. Wind carries fine dust and grit that settles deep into the grooves of the boards. Rinse away loose dirt regularly so the abrasive grit does not grind into the grain under foot traffic. Trees drop pine needles, cones, and cottonwood fluff that gather between deck boards and trap moisture. Clear these deposits out of board seams promptly so damp pockets do not form. In areas with wet spring and fall seasons, spring pollen settles as a sticky film while falling fall leaves leave dark tannin stains. Sweep pollen and fallen foliage off the surface before rain sets the marks into the wood fibers. In warm, shaded spots where dew and frequent rain keep boards damp, green algae and dark mildew spots can grow almost all year. Treat algae growth early so the surface stays safe to walk on.
