Ghana's combination of harmattan dust, heavy rainfall, and humidity means exterior surfaces get dirty fast. Driveways turn grey with grime, walls develop algae streaks, and roofs collect moss within months of being cleaned. Pressure washing restores all of these surfaces without harsh chemicals.
Hard Wash vs Soft Wash
Hard washing uses high-pressure water alone and is ideal for concrete, interlock pavers, and driveways that can take the force. Soft washing combines lower pressure with a gentle cleaning solution, and is the safer choice for roofing sheets, painted render, and delicate facades — it removes algae and lichen without damaging the surface.
| Surface | Recommended Method |
|---|---|
| Concrete driveway / interlock | Hard wash |
| Painted exterior walls | Soft wash |
| Roofing sheets / aluminium roofs | Soft wash |
| Pool decks & patios | Hard wash (non-slip finish) |
Why Harmattan Makes This Worse
Between November and March, fine Sahara dust settles on every outdoor surface in Accra. Combined with rain showers, this dust mixes into a film that's difficult to remove with a hose alone. A pressure wash before and after harmattan season keeps walls and driveways looking fresh year-round.
