Avoid power washing during the hottest part of the day or when it’s raining. High heat can make the water evaporate too fast, leaving your paint or sealant looking dull. Rain can also make the pressure washer less effective and could lead to water damage if the spray isn’t properly directed. Stick to a time when the weather is clear, and you’ll get the cleanest results without any extra stress.
