Wood Pergolas
Untreated or unsealed wood pergolas gray and crack faster under Arizona's UV exposure than in milder climates. Gentle cleaning to remove dust and mildew, paired with periodic re-staining, extends the wood's life and appearance significantly.
Metal and Vinyl Structures
Metal pergolas need attention to rust-prone joints and connection points, similar to iron patio furniture, while vinyl structures are more resistant to UV damage but still accumulate dust film and occasional mineral spotting from irrigation overspray that benefits from periodic cleaning.
Cleaning Approach
Low-pressure soft washing removes dust and organic debris across all pergola materials without the risk of splintering wood, denting vinyl, or scratching painted metal that higher-pressure methods can cause.
