How to Take Care of External Roller Blinds? Cleaning and Maintenance

External roller shutters are becoming increasingly popular in homes, offices, and shops. Once associated solely with burglary protection, external blinds now offer a range of practical and decorative benefits. What’s more, they can help you save money and energy!

High-quality external roller shutters can provide comfort and functionality for many years. That’s why it’s essential to invest in well-made, aesthetically pleasing products. With many models available, differing in appearance, materials, and features, there’s something suitable for every building. However, one crucial point must not be overlooked: even the best shutters will not serve their purpose unless they are properly installed and regularly cleaned and maintained.

In this article, we’ll explore how to care for your external roller shutters and share some helpful maintenance tips.

Why Is Regular Maintenance of External Roller Blinds Important?

As mentioned earlier, both internal and external roof window blinds offer numerous advantages - from improved security to energy efficiency and enhanced sound insulation.

However, the elements that protect you from sunlight, rain, and even hail are also exposed to daily wear and tear. Dirt can accumulate directly on the armouring and housing, especially if the roller shutters are not concealed. This makes regular cleaning essential.

Thankfully, maintenance doesn't have to be time-consuming, provided it's carried out regularly and damage is avoided. With proper care, your shutters can remain in excellent condition for many years.

What Tools and Cleaning Products Are Best for Roller Blinds?

Now that you know why cleaning is important, let’s talk about what to use.

The key is to use soft cloths or sponges. Avoid rough materials, which can scratch the surface, especially if there are sand particles present.

Use water with a small amount of mild, neutral washing-up liquid to clean the blinds. Avoid aggressive chemicals that can cause corrosion or discolour the lacquered finish. Steer clear of any solvents or products containing esters, alcohol, ketones, or strong fragrances.

If your blinds have greasy stains or soot, water alone might not be enough. In these cases, a stronger but gentle cleaner, free from aromatic petroleum hydrocarbons, can be used. There are specialist cleaners on the market designed for delicate surfaces.

Step-by-Step Guide to Cleaning Your External Roller Blinds

To keep your exterior (and interior) roller shutters working smoothly, follow these cleaning steps:

1. Switch off the power (if the blinds are motorised).

2. Fully extend the blinds to expose the armouring.

3. Inspect the surface for any loose particles that could scratch the surface. Remove them carefully.

4. Wipe the blinds with a damp, soft cloth.

5. Add a mild dishwashing liquid to your cloth or sponge and gently wipe again.

6. Avoid using harsh cleaners or rough sponges.

7. Use a pressure washer cautiously, with low pressure and at a safe distance to avoid damage.

8. Clean the seals periodically to prevent condensation build-up.

9. Apply a preservative product to protect the surface and prolong the blinds’ lifespan.

Best Practices for Maintaining the Blind Mechanism

Roller shutters consist of more than what’s visible, they also include internal mechanisms that may be hidden in built-in systems.

It’s advisable to have the roller shutter housing inspected annually. This ensures early detection of issues such as wear to the lifting cords. Regular servicing should also include checks of seals and guides, where dust and pollen often accumulate and can hinder performance.

How to Protect Your Roller Blinds from Weather Damage

External blinds are exposed to harsh weather conditions. Unlike internal blinds, external versions face direct sun, wind, rain, and temperature fluctuations. That’s why they require extra care.

We’ve already covered maintenance tips, but it’s especially important to focus on:

• The armouring

• The guides

• The lifting mechanism

• All moving parts

Wipe these components regularly with a damp cloth, oil any necessary parts, and apply protective treatments when needed. This will help extend the system’s lifespan and maintain both comfort and safety.

What to Avoid When Cleaning and Maintaining Roller Blinds

To protect your blinds during cleaning, avoid these common mistakes:

• Don’t wipe over sand or grit—it can scratch the surface.

• Avoid coarse or abrasive sponges.

• Never use harsh cleaners containing ketones, alcohol, or petroleum derivatives.

• If using a pressure washer, keep the pressure low to prevent damage.

When Should You Consider Professional Cleaning or Repair?

If your shutters are located in hard-to-reach areas, such as loft windows, professional cleaning may be the safer and more effective option.

Additionally, it’s a good idea to schedule an annual professional inspection and maintenance service. This can significantly extend the lifespan of your shutters and help you avoid costly repairs in the future.
