Wood, composite and what each one needs
Pressure-treated pine and cedar are the most common woods in backyards here. Both soften under high pressure, and aggressive washing raises splinters and leaves fuzzy, uneven patches. Composite boards are tougher, though they can trap mildew in the grooves and embossed grain.
We start with a cleaner that lifts the growth, scrub where needed and rinse at a pressure appropriate for the material. A brightener may follow to restore color. Fasteners, railings and lattice are checked, because loose or rusted parts are easier to deal with before sealing. Salt air near the water and leaf litter from trees add their own staining, so we look at the way each yard collects debris.
