House exteriors in Nairobi accumulate red dust, algae, and mold from rainy seasons and pollution, dulling curb appeal and risking structural damage. Bestcare Cleaning shares proven tips and tools for safe, effective cleaning that boosts property value without harm.
Preparation Essentials
Start with safety: wear goggles, gloves, and non-slip shoes. Cover plants with tarps and wet them first to protect from runoff. Test cleaners on small areas—brick takes mild soap, while paint demands pH-neutral formulas. Clear debris like leaves from gutters to prevent water backups.
Key Cleaning Tips by Surface
Tailor methods to materials for best results.
Brick and Stone Walls: Mix dish soap with warm water; scrub gently with a soft brush to lift soot without eroding mortar. For moss, apply vinegar solution (1:1 water) and let sit 15 minutes before rinsing. Avoid pressure over 1,500 PSI to prevent cracks.
Painted Siding: Use a soft wash—diluted bleach or biocide spray kills algae roots without stripping paint. Work top-down in shaded areas to avoid streaking. Rinse within 10 minutes.
uPVC Cladding and Windows: Warm soapy water with a microfiber cloth removes grime safely. For oxidation, add baking soda paste; never use abrasives that scratch.
Roof Tiles and Gutters: Manually scrape moss, then soft-spray biocide. Check for loose tiles first—Nairobi winds demand caution.
Driveways and Patios: Pressure wash concrete at low angle to dislodge dirt; follow with eco-sealer for dust resistance.
Clean in early morning or late afternoon to evade direct sun, which bakes residues.
