Wood vs Composite Different Washing Approaches
Wood Deck Washing
- PSI: 1,200–1,500 max (higher damages grain)
- Tip: 40-degree fan (never zero-degree)
- Direction: with the grain, 12–18 inches from surface
- Follow with wood brightener (oxalic acid)
- Dry 48–72 hours before staining
- Frequency: annually (spring before stain)
Composite Deck Washing
- Preferred: soft wash (low pressure + cleaner)
- Max PSI if needed: 1,500 with 40-degree tip
- Never use zero-degree or turbo nozzle
- Use brand-recommended cleaner (Corte Clean, etc.)
- No brightener needed (composite doesn't gray)
- Frequency: 1–2x yearly (pollen + mold removal)
What We Remove
- Green mold/algae: Common on shaded sections Virginia humidity breeds it fast
- Black mildew spots: From organic debris (leaves, pollen) sitting on the surface
- Gray oxidation (wood only): UV damage turns wood silver/gray brightener restores natural color
- Pollen buildup: Virginia spring pollen coats everything yellow film needs removal
- Ground-in dirt: Foot traffic, pet paws, mud tracked from yard
- Stain/sealer residue: Old failing stain needs removal before re-staining
