Why Cleaning Your Pergola Matters?

Your pergola isn’t just a structure, it’s part of your lifestyle. It creates shade, adds beauty, and makes your outdoor space enjoyable. But over time, dust, rain, and pollution can make it look dull.

Regular cleaning and care can:

  • Make your pergola last longer

  • Keep it safe from rust, mould, and stains

  • Protect the colour and finish

  • Save you money on future repairs

So, spending a little time on maintenance keeps your pergola looking like new — and keeps your garden looking stunning.

7 Expert Pergola Maintenance Tips

Here are seven practical and easy ways to keep your pergola clean, safe, and beautiful all year long.

1. Start with a Gentle Wash

Use warm water and mild soap. A soft cloth or sponge works best.
Avoid strong chemicals, as they can damage the paint or coating, especially on aluminium garden pergolas.

If your pergola has a roof, start cleaning from the top and move downwards to avoid streaks.

2. Rinse Regularly

In the UK, the weather can be unpredictable. After rainfall or windy days, rinse your pergola with a hose to remove dirt or pollen.
This prevents build-up that can lead to stains or discolouration.

3. Remove Dust from Corners and Joints

Dust and leaves often collect in hidden spots, especially around screws, joints, or louvre gaps.
Use a soft brush or vacuum cleaner to remove them gently.
For modern garden pergolas UK, keeping joints clean also helps moving parts last longer.

4. Check for Damage or Rust

Inspect your pergola once a month. Look for signs like chipped paint, rust spots, or loose bolts.
If you find anything unusual, fix it right away. For metal frames, a small rust mark can grow quickly if ignored.

You can touch up paint with a small brush or spray to stop rust from spreading.

5. Clean the Roof and Sides Properly

If your pergola has glass sides or a retractable roof, clean them using a soft glass cleaner or a vinegar solution.
Avoid abrasive sponges; they can leave scratches.
For bespoke aluminium pergola UK designs, the roof panels often have protective coatings that need gentle cleaning.

6. Protect Against Mould and Mildew

The damp UK weather can cause mould, especially on wooden or fabric parts.
Mix equal parts of vinegar and water, spray on the area, and wipe it clean.
Let it dry completely before using again.

If your pergola includes lighting or blinds (like an aluminium pergola with blinds UK), make sure all areas stay dry to prevent electrical damage.

7. Add a Protective Coating

After cleaning, use a clear protective spray suitable for your pergola’s material, metal, or aluminium.
It helps repel water and gives a polished look.

This final touch can make even luxury pergolas UK look fresh and new throughout the year.
