What is the best time of year to power wash?

Spring and early fall are widely considered the best times to power wash most exterior surfaces. Spring cleaning removes winter grime, pollen, and any mold or mildew that developed during cold, damp months, giving surfaces a fresh start for the season. Fall cleaning clears summer dirt, algae, and organic buildup before it has a chance to sit under snow or ice through winter, which can make stains harder to remove later. Avoid power washing in freezing temperatures, since water can freeze in cracks or on surfaces before it has a chance to dry, potentially causing damage. Extremely hot, direct sunlight can also cause cleaning solutions to dry too quickly, reducing their effectiveness, so early morning or overcast days are generally preferable within either season.
