What causes hard water stains in Nairobi bathrooms and how do I remove them?

Hard water stains — white, chalky, or rust-coloured deposits on taps, showerheads, tiles, and glass — are one of the most common bathroom problems in Nairobi homes.

Why Nairobi Water Causes Scale

Nairobi’s municipal supply is hard water, containing elevated dissolved calcium and magnesium. When it evaporates from surfaces, it leaves calcium carbonate (limescale). Borehole areas like Karen, Runda, and Gigiri often have even harder water.

Removal by Severity

Mild Scaling

• White vinegar (50:50 with water) — apply, leave 15–30 minutes, scrub with soft brush
• Lemon juice — natural citric acid; effective on chrome taps and showerheads

Moderate Scaling

• Citric acid powder in warm water — more concentrated than vinegar; leave 30–60 minutes
• Descaling products (Harpic, Viakal) — available in Nairobi supermarkets

Heavy Calcification

• Soak showerheads in undiluted white vinegar overnight
• Professional steam cleaning — heat + pressure loosens calcified deposits without abrasion

Prevention

• Squeegee shower screens after each use
• Wipe taps dry with microfibre cloth
• Consider a water softener for very hard water areas
