Calima Stains on Your Walls? Here’s What To Do Before It Gets Worse

If you’ve looked at your walls recently and noticed a sandy, streaky film — you’re not alone.

After the recent calima and rain across Almería, many homes are left with visible dust stains on exterior walls, terraces, and outdoor areas.

So what’s actually happening — and what should you do about it?

🌬️ What causes calima stains?

Calima is a weather phenomenon where fine desert dust from the Sahara is carried across to Spain.

When it rains, that dust mixes with water and settles on surfaces — leaving behind the muddy, sandy residue you’re now seeing on walls and outdoor spaces.

🧽 Can you clean it yourself?

In some cases, yes — especially if the staining is light.

You can try:

• Rinsing walls with clean water
• Using a hose or light pressure wash
• Gently brushing affected areas

⚠️ Be careful with strong pressure or harsh chemicals, as these can damage paint or leave uneven patches.

🎨 When cleaning isn’t enough

If the stains have:

• Soaked into the paint
• Left patchy or uneven marks
• Made the property look dull or tired

…then cleaning alone won’t fully fix the issue.

In these cases, repainting is often the best way to restore your home’s appearance properly.

⏳ Why it’s best not to leave it

Calima residue can sit on surfaces longer than you think.

Leaving it untreated can:

• Make stains harder to remove
• Affect the look of your property over time
• Lead to uneven colouring or fading
